So I'm trying to add top 10 for my leaderboard this is the code that I'm using for the leveling system and leaderboard but I dont know how to add the top 10 and I need it because when you type the command it just spams because a lot of people have talked so please help.
client.on("message", async (message) => {
if (message.author.bot) return;
if (message.channel.type === "dm") {
return;
}
const dm = client.users.cache.get(message.author.id);
if (!db[message.author.id])
db[message.author.id] = {
userid: message.author.id,
xp: 0,
level: 0,
};
db[message.author.id].xp++;
let userInfo = db[message.author.id];
if (userInfo.xp > 99) {
userInfo.level++;
userInfo.xp = 0;
dm.send(
new Discord.MessageEmbed()
.setTitle(
`${levelup}Level up${levelup}\n${levelup}Level: ${userInfo.level} ${levelup}`
)
.setColor("#E2DF09")
.setTimestamp()
);
}
if (
message.content.toLowerCase().startsWith(prefix + "rank") ||
message.content.toLowerCase().startsWith(prefix + "level")
) {
let userInfo = db[message.author.id];
let member = message.mentions.members.first();
let embed = new Discord.MessageEmbed()
.setColor("#E2DF09")
.addField("Level", `${info}` + userInfo.level + `${info}`)
.addField("XP", `${info}` + userInfo.xp + "/100" + `${info}`)
.setFooter(
`${message.author.tag}`,
`${message.author.avatarURL({ dynamic: true })}`
);
if (!member) return message.channel.send(embed);
let memberInfo = db[member.id];
let embed2 = new Discord.MessageEmbed()
.setColor("#E2DF09")
.addField("Level", `${info}` + memberInfo.level + `${info}`)
.addField("XP", `${info}` + memberInfo.xp + "/100" + `${info}`);
message.channel.send(embed2);
} else if (
message.content.toLowerCase().startsWith(prefix + "leaderboard") ||
message.content.toLowerCase().startsWith(prefix + "lb")
) {
const embed = new Discord.MessageEmbed()
.setTitle("Leaderboard")
.setColor("#E2DF09");
const c = Object.entries(db).sort((a, b, d) => b[1].level - a[1].level);
for (const [key, value] of c) {
embed.addField(
`\u200B`,
`<#${value.userid}>\nLevel: ${value.level} | XP: ${value.xp}`
);
}
message.channel.send(embed);
}
fs.writeFile("./db/database.json", JSON.stringify(db), (error) => {
console.error();
});
});
and also this is how the json file looks like
I use the userid for the leaderboard tag
{"630812692659044352":{"userid":"630812692659044352","xp":31,"level":32}
This is how the leaderboard looks like but I want to add the numbers next to the username and for the 1st, 2nd, 3rd i want to add like a trophy or something but its not working out on my side .
Here is something I think would work (I tested it on an online site)
var ranks = {
'SOMEUSERID': {
userid: 'SOMEUSERID',
rank: 0,
xp: 45
},
'ANOTHERUSERID': {
userid: 'THEUSERID',
rank: 0,
xp: 70
}
}
//^^EXAMPLE RANKS, DONT ADD THESE^^
var leaderboard = []
for(const i in ranks) {
var person = ranks[i];
leaderboard.push(person)
}
//^^LOOP THROUGH ALL USERS^^
leaderboard.sort((b, a) => ((a.rank+1)*(a.xp)) - ((b.rank+1)*(b.xp)))
//^^SORT BY (RANK+1)*XP, in descending order^^
var ranksSorted = leaderboard.map(u => u.rank);
var xpSorted = leaderboard.map(u => u.xp)
var usersSorted = leaderboard.map(u => u.userid)
//ranksSorted, xpSorted, and usersSorted are synced
//...
//top 10 leaderboard within one string
var str = '';
for(let i = 0; i<=10 && i<leaderboard.length;i++) {
str += usersSorted[i] + '\n' + ranksSorted[i] + ' | ' + xpSorted[i] + '\n'
//YOU CAN ALSO ACCESS WHICH PLACE THEY ARE WITH i+1
}
So you don’t have to save it on string, instead of adding it to the string, you can do add embed field, like this:
for(let i = 0; i<=10 && i<leaderboard.length;i++) {
someEmbed.addField(client.users.cache.get(usersSorted[i]).tag, ranksSorted[i] + ' | ' + xpSorted[i])
}
EDIT: rank*xp wouldn’t work well. 1*28 for example is more than 2*13. Do Math.pow().
leaderboard.sort((b, a) => ((a.rank+1)*(a.xp)) - (Math.pow((b.rank+1), 10)*(b.xp)))
//instead of the previous leaderboard.sort
This way, rank 1 xp 99 is less than rank 2 xp 1

Tanaike helped me with this amazing script using Cheerio. The original was for Letterboxd, but this one is to pull in a watchlist from Trakt.tv (sample watchlist).
As it is right now it pulls in the watched date and the title, but I'd also like to pull in the content from the meta tag for each item.
<meta content="8 Million Ways to Die (1986)" itemprop="name">
I tried using $('[itemprop="name"]').attr('content'); but it doesn't accept the .attr piece.
Here is the full script as it is now, returning the watched date in the Col1 and the title in Col2.
/**
* Returns Trakt watchlist by username
* #param pages enter the number of pages in the list. Default is 10
* #customfunction
*/
function TRAKT(pages=10) {
const username = `jerrylaslow`
const maxPage = pages;
const reqs = [...Array(maxPage)].map((_, i) => ({ url: `https://trakt.tv/users/`+ username +`/history/all/added?page=${i + 1}`, muteHttpExceptions: true }));
return UrlFetchApp.fetchAll(reqs).flatMap((r, i) => {
if (r.getResponseCode() != 200) {
return [["Values couldn't be retrieved.", reqs[i].url]];
}
const $ = Cheerio.load(r.getContentText());
const ar = $(`a.titles-link > h3.ellipsify, h4 > span.format-date`).toArray();
return [...Array(Math.ceil(ar.length / 2))].map((_) => {
const temp = ar.splice(0, 2);
const watchDate = Utilities.formatDate(new Date($(temp[1]).text().trim().replace(/T|Z/g, " ")),"GMT","yyyy-MM-dd");
const title = $(temp[0]).text().trim();
return [watchDate,title];
});
});
}
The values can be pulled with this, so I know there isn't any sort of blocking in play.
=IMPORTXML(
"https://trakt.tv/users/jerrylaslow/history",
"//meta[#itemprop='name']/#content")
Any help is appreciated.
In order to achieve your goal, in your script, how about the following modification?
Modified script:
function TRAKT(pages = 10) {
const username = `jerrylaslow`
const maxPage = pages;
const reqs = [...Array(maxPage)].map((_, i) => ({ url: `https://trakt.tv/users/` + username + `/history/all/added?page=${i + 1}`, muteHttpExceptions: true }));
return UrlFetchApp.fetchAll(reqs).flatMap((r, i) => {
if (r.getResponseCode() != 200) {
return [["Values couldn't be retrieved.", reqs[i].url]];
}
const $ = Cheerio.load(r.getContentText());
const ar = $(`a.titles-link > h3.ellipsify, h4 > span.format-date`).toArray();
return [...Array(Math.ceil(ar.length / 2))].map((_) => {
const temp = ar.splice(0, 2);
const c = $(temp[0]).parent('a').parent('div').parent('div').find('meta').toArray().find(ff => $(ff).attr("itemprop") == "name"); // Added
const watchDate = Utilities.formatDate(new Date($(temp[1]).text().trim().replace(/T|Z/g, " ")), "GMT", "yyyy-MM-dd");
const title = $(temp[0]).text().trim();
return [watchDate, title, c ? $(c).attr("content") : ""]; // Modified
});
});
}
When this modified script is run, the value of content is put to 3rd column. If you want to put it to other column, please modify return [watchDate, title, c ? $(c).attr("content") : ""];.
Hello everyone I am a junior web dev. and I've been stuck on this task for weeks now :[]. I need an input field that will show default text coming from the backend. Restrictions I need for this input field are: The input line should break after reaching 30 characters and some parts of default text should be noneditable.
//Here's the closest solution that I came up
import React, { useEffect } from "react";
import styles from "./TextEditor.module.css";
const TextEditor = (props) => {
var limit = 80000; //height limit
let defaultvalueArr = props.data.variables.map((vari, index) => {
return vari.texts.map((p, index) => {
return p;
});
});
useEffect(() => {
const box = document.getElementById(props.title);
var charlimit = 30; // char limit per line
var space;
box.onkeyup = function () {
var lines = box.value.split("\n");
console.log(box.value, "box.value");
for (var i = 0; i < lines.length; i++) {
if (lines[i].length <= charlimit) continue;
var j = 0;
space = charlimit;
while (j++ <= charlimit) {
if (lines[i].charAt(j) === " ") space = j;
}
lines[i + 1] = lines[i].substring(space + 1) + (lines[i + 1] || "");
lines[i] = lines[i].substring(0, space);
}
box.value = lines.slice(0, 500).join("\n");
};
box.oninput = function() {
box.style.height = "";
box.style.height = Math.min(box.scrollHeight, limit) + "px";
};
box.value = defaultvalueArr.join("\n");
}, []);
return (
<div className={styles.TextEditor}>
<textarea
id={props.title}
className={styles.TextArea}
// rows={defaultvalueArr[0].length}
></textarea>
</div>
);
};
export default TextEditor;
output
the problem with this solution is that when the number of characters reaches 30 the cursor jumps at the end of text
When running our AngularJS app in IE11 everything looks great in the debugger, but when our app encodes the data as JSON to save to our database, we get bad results.
Our app obtains a record from our database, then some manipulation is done and then the data is saved back to the server from another model.
Here is the data I got back from the server in the setAttendanceGetSInfo() function below:
{"data":{"Start":"2014-10-16T19:36:00Z","End":"2014-10-16T19:37:00Z"},
This is the code used to "convert the data" to 3 properties in our model:
var setAttendanceGetSInfo = function (CourseId, PID) {
return setAttendanceInfo(CourseId, PID)
.then(function (result) {
return $q.all([
$http.get("../api/Axtra/getSInfo/" + model.event.Id),
$http.get("../api/Axtra/GetStartAndEndDateTime/" + aRow.Rid)
]);
}).then(function (result) {
var r = result.data;
var e = Date.fromISO(r.Start);
var f = Date.fromISO(r.End);
angular.extend(model.event, {
examDate: new Date(e).toLocaleDateString(),
examStartTime: (new Date(e)).toLocaleTimeString(),
examEndTime: (new Date(f)).toLocaleTimeString()
});
return result.sInfo;
});
};
fromISO is defined as:
(function(){
var D= new Date('2011-06-02T09:34:29+02:00');
if(!D || +D!== 1307000069000){
Date.fromISO= function(s){
var day, tz,
rx=/^(\d{4}\-\d\d\-\d\d([tT ][\d:\.]*)?)([zZ]|([+\-])(\d\d):(\d\d))?$/,
p= rx.exec(s) || [];
if(p[1]){
day= p[1].split(/\D/);
for(var i= 0, L= day.length; i<L; i++){
day[i]= parseInt(day[i], 10) || 0;
};
day[1]-= 1;
day= new Date(Date.UTC.apply(Date, day));
if(!day.getDate()) return NaN;
if(p[5]){
tz= (parseInt(p[5], 10)*60);
if(p[6]) tz+= parseInt(p[6], 10);
if(p[4]== '+') tz*= -1;
if(tz) day.setUTCMinutes(day.getUTCMinutes()+ tz);
}
return day;
}
return NaN;
}
}
else{
Date.fromISO= function(s){
return new Date(s);
}
}
})()
Take a look at the screenshot of the event model data:
But, if I eval the event model using JSON.stringify(model.event), I get this:
{\"examDate\":\"?10?/?16?/?2014\",\"examStartTime\":\"?2?:?44?:?00? ?PM\",\"examEndTime\":\"?2?:?44?:?00? ?PM\"}
And this is the JSON encoded data that actually got stored on the DB:
"examDate":"¿10¿/¿16¿/¿2014","examStartTime":"¿2¿:¿36¿:¿00¿ ¿PM","examEndTime":"¿2¿:¿37¿:¿00¿ ¿PM"
What is wrong here and how can I fix this? It works exactly as designed in Chrome and Firefox. I have not yet tested on Safari or earlier versions of IE.
The toJSON for the date class isn't defined perfectly the same for all browsers.
(You can see a related question here: Discrepancy in JSON.stringify of date values in different browsers
I would suspect that you have a custom toJSON added to the Date prototype since your date string doesn't match the standard and that is likely where your issue is. Alternatively, you can use the Date toJSON recommended in the above post to solve your issues.
First, I modified the fromISO prototype to this:
(function () {
var D = new Date('2011-06-02T09:34:29+02:00');
if (!D || +D !== 1307000069000) {
Date.fromISO = function (s) {
var D, M = [], hm, min = 0, d2,
Rx = /([\d:]+)(\.\d+)?(Z|(([+\-])(\d\d):(\d\d))?)?$/;
D = s.substring(0, 10).split('-');
if (s.length > 11) {
M = s.substring(11).match(Rx) || [];
if (M[1]) D = D.concat(M[1].split(':'));
if (M[2]) D.push(Math.round(M[2] * 1000));// msec
}
for (var i = 0, L = D.length; i < L; i++) {
D[i] = parseInt(D[i], 10);
}
D[1] -= 1;
while (D.length < 6) D.push(0);
if (M[4]) {
min = parseInt(M[6]) * 60 + parseInt(M[7], 10);// timezone not UTC
if (M[5] == '+') min *= -1;
}
try {
d2 = Date.fromUTCArray(D);
if (min) d2.setUTCMinutes(d2.getUTCMinutes() + min);
}
catch (er) {
// bad input
}
return d2;
}
}
else {
Date.fromISO = function (s) {
return new Date(s);
}
}
Date.fromUTCArray = function (A) {
var D = new Date;
while (A.length < 7) A.push(0);
var T = A.splice(3, A.length);
D.setUTCFullYear.apply(D, A);
D.setUTCHours.apply(D, T);
return D;
}
Date.toJSON = function (key) {
return isFinite(this.valueOf()) ?
this.getUTCFullYear() + '-' +
f(this.getUTCMonth() + 1) + '-' +
f(this.getUTCDate()) + 'T' +
f(this.getUTCHours()) + ':' +
f(this.getUTCMinutes()) + ':' +
f(this.getUTCSeconds()) + 'Z' : null;
};
})()
Then I added moment.js and formatted the dates when they get stored:
var SaveAffRow = function () {
// make sure dates on coursedate and event are correct.
var cd = model.a.courseDate;
var ed = model.event.examDate;
var est = model.event.examStartTime;
var eet = model.event.examEndTime;
model.a.courseDate = moment(cd).format("MM/DD/YYYY");
model.event.examDate = moment(ed).format("MM/DD/YYYY");
model.event.examStartTime = moment(est).format("MM/DD/YYYY hh:mm A");
model.event.examEndTime = moment(eet).format("MM/DD/YYYY hh:mm A");
affRow.DocumentsJson = angular.toJson({a: model.a, event: model.event});
var aff = {};
if (affRow.Id != 0)
aff = affRow.$update({ Id: affRow.Id });
else
aff = affRow.$save({ Id: affRow.Id });
return aff;
};
and when they get read (just in case they are messed up already):
var setAttendanceGetSInfo = function (CourseId, PID) {
return setAttendanceInfo(CourseId, PID)
.then(function (result) {
return $q.all([
$http.get("../api/Axtra/getSInfo/" + model.event.Id),
$http.get("../api/Axtra/GetStartAndEndDateTime/" + aRow.Rid)
]);
}).then(function (result) {
var r = result.data;
var e = Date.fromISO(r.Start);
var f = Date.fromISO(r.End);
angular.extend(model.event, {
examDate: moment(e).format("MM/DD/YYYY"),
examStartTime: moment(e).format("MM/DD/YYYY hh:mm A"),
examEndTime: moment(f).format("MM/DD/YYYY hh:mm A")
});
return result.sInfo;
});
};
I'm trying to build a JSON out of multiple requests on my mongodb.
since I'm not using DBRef, I have to build the "table joints" by myself, and that's how I ended up in this mess.
This is the code that is giving me the headaches from a couple of days now.
(the mongo part is done with mongoskin)
var getUserFeed = function(thelimit, out) {
userfeed = db.collection("userfeed");
apparel = db.collection("apparel");
store = db.collection("stores");
if(thelimit)
args = {limit:thelimit, sort: [['date',-1]]};
userfeed.find({},args).toArray(function(e, feed) {
if (e) console.log("error: ", e);
// gather aparel infos
var i=0;
var ret_feeds = [];
feed.forEach(function(cur_feed) {
var outfits=[];
console.log("beginning with: " + cur_feed.url);
var resfeed = "";
resfeed = cur_feed;
resfeed.url = baseurl + snapurl + resfeed.url + "_small.jpg";
i=0;
cur_feed.apparel_ids.forEach(function(item) {
/*>>*/ apparel.find({"_id": item},{limit:1}).toArray(function(e, results) {
console.log(">>>>>>>>>>> APPAREL_FIND { i:" + i + "}");
if (e) console.log("error: ", e);
results = results[0];
if(results.apparel_cat == 1)
url_subcat = "pants/";
else if(results.apparel_cat == 2)
url_subcat = "shirts/";
else if(results.apparel_cat == 2)
url_subcat = "tshirts/";
results.thumb = baseurl + outfiturl + url_subcat + results.apparel_id + "/front.jpg";
results.size = "M"; ///// TOBE REAL VERY SOON
results.gallery = [
baseurl + outfiturl + url_subcat + results.apparel_id + "/model.jpg",
baseurl + outfiturl + url_subcat + results.apparel_id + "/front.jpg"
];
outfits.push(results); // quick and dirty, 2 b refined..
i++;
if(i>=cur_feed.apparel_ids.length)
{
// pack it up
// resfeed.url = resfeed.url;
resfeed.outfits = outfits;
resfeed.fav = false;
resfeed.bough = false;
// retrieve store infos
/*>>>*/ store.find({"_id":resfeed.store_id}, {limit: 1}).toArray(function(e, resstore) {
console.log("\t############# STORE_FIND { i:" + i + "}");
if (e) console.log("error: ", e);
resfeed.store = resstore[0];
resfeed.store.class = "hem";
ret_feeds.push(resfeed);
if(ret_feeds.length >= feed.length)
{
console.log("\t\t######################calling return [ ret_feeds.length = " + ret_feeds.length + " feed.length = " + feed.length);
out.send(ret_feeds);
}
});
}
});
});
});
});
}
This code fails, because returns the json before finishing its task, so the next time that it tries to return another json it crashes miserably due to the fact the the headers have already been sent.
Now as you can see, I have 3 collections: userfeed, apparel and stores.
the goal of this function is to retrieve all the items in the userfeed collection, extract the outfits (based on the outfit_id array that is part of the userfeed collection), and also extract the store infos related in the same way to each userfeed entry, like so:
I know that async.js or equivalent is the way to go: I've red like a gazillion of other posts here on SO, but I still can't get my head around it, probably because the whole mechanism behind the async.js or flow control in general it's still out of focus in my mind.
I'm still a noob at node :)
UPDATE
I think I found the right path for understanding here: http://www.sebastianseilund.com/nodejs-async-in-practice
this guy made a terrific job in describing use-case by use-case all the ways to apply async.js to your code.
I'll post the solution as soon as I get around it.
UPDATE 2
Thanks to the above dude I could work out a working solution, below is the answer.
After so much struggling I have finally managed to get a solution.
async.js was the answer as I was (obviously) suspecting.
FYI here's the working code.
If you like to point out improvements or anything else, you are more than welcome
var getUserFeed = function(thelimit, out) {

I am working on some CRM 2011 Online customisations and I need to get an entity using javascript.
The entity I need will be based on the ID value of another field (a Contact entity) - this Contact ID I can get fine.
The entity I want is a custom entity. There may be multiple matches based on the Contact ID so I just want to get the first one in the list (order not important)
So far I have looked into a few ways to do this...
OData - I couldn't find enough examples on this as to what query expressions I can create, also I don't know if/how to make this work for custom entities
FetchXML - I can create a nice FetchXML query using the built-in "advanced find" too and would be happy to call this from javascript if anyone can help? I found one promising answer here but I could not see how the "results" return data was being set (Service.Fetch function)
SOAP Request - First thing I tried is a similar method as I could have done in CRM 4 but this does not seem to work. Although the request executes, my result data just seems to be empty. This is all I have code for so if any one can spot a problem with the code below then that would be great.
EDIT: I have spotted some redundant query data (I had removed link opening tags but left closing tags) - since removing this I now get XML result data... however, the where clause does not seem to apply (just get list of all entities)

Sorry about the big code post but hopefully somebody who has a better understanding can help
Firstly, thanks to GlennFerrieLive for his answer post. The samples I found with the Dynamics CRM 2011 SDK (well just one in particular) really helped and the JSON parser included was perfect for the job!
I am posting this answer to give a full example of how I did it with some important comments to pay attention to which may not be so obvious from the SDK examples.
Get selected ID value from lookup field
The aim of my task was to use javascript to get set a lookup field, based on the selected data of another lookup entity. The entity to set is "new_vehicle" and the entity to query on is "customer".
First job is to get the ID value of the contact lookup field...
var customerItem = Xrm.Page.getAttribute("customerid").getValue();
var customerID = customerItem[0].id;
Querying an entity using an ID
Next is the part where I used the customerID value to find the vehicle that is currently assigned to them (the entity I want to use to set a lookup field).
First problem I found was that when querying with OData, the ID value does not seem to work with curly brackets {} - so these need to be removed...
customerID = customerID.replace('{', '').replace('}', '');
Next we get the oDataPath...
var oDataPath = Xrm.Page.context.getServerUrl() + "/xrmservices/2011/organizationdata.svc";
Then we can construct the OData query...
var filter = "/new_vehicleSet?" +
"$select=new_vehicleId,new_Registration" +
"&$filter=new_PrimaryDriver/Id eq (guid'" + customerID + "')" +
"&$orderby=new_LastAllocationDate desc" +
"&$top=1";
NOTE: There are a couple of important things to note here...
When using a guid value you must explicitly say it is a guid using (guid'xxx')
When filtering by a lookup entity (e.g. new_PrimaryDriver) you must append the value to query (e.g. Id) - this results in new_PrimaryDriver/Id
Once we have the query setup we can request the data as follows...
var retrieveRecordsReq = new XMLHttpRequest();
retrieveRecordsReq.open("GET", oDataPath + filter, true);
retrieveRecordsReq.setRequestHeader("Accept", "application/json");
retrieveRecordsReq.setRequestHeader("Content-Type", "application/json; charset=utf-8");
retrieveRecordsReq.onreadystatechange = function () {
if (this.readyState == 4) {
if (this.status == 200) {
var retrievedRecords = JSON.parse(retrieveRecordsReq.responseText).d;
if(retrievedRecords.results.length > 0)
{
var vehicle = retrievedRecords.results[0];
SetLookup("new_replacedvehicle", vehicle.new_vehicleId, vehicle.new_Registration, "new_vehicle");
}
}
}
};
retrieveRecordsReq.send();
Note that this is an asynchronous call and the onreadystatechange function will be processed upon completion, in this function we do a couple of checks to see if it was a success and the we parse the resulting JSON data - the JSON.Parse function has been included at the bottom of this post (but is available from the SDK)
Setting a lookup field using the entity queried above
The other function to make note of here is SetLookup which is just a simple helper function I added to set a lookup field. This is as follows...
function SetLookup(fieldName, idValue, textValue, typeValue)
{
var value = new Array();
value[0] = new Object();
value[0].id = idValue;
value[0].name = textValue;
value[0].typename = typeValue;
Xrm.Page.getAttribute(fieldName).setValue(value);
}
JSON parse function
This is the JSON helper function that was used in the above code (JSON.parse), pasted as it was found in the SDK...
if (!this.JSON) { this.JSON = {}; } (function () { function f(n) { return n < 10 ? '0' + n : n; } if (typeof Date.prototype.toJSON !== 'function') { Date.prototype.toJSON = function (key) { return isFinite(this.valueOf()) ? this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z' : null; }; String.prototype.toJSON = Number.prototype.toJSON = Boolean.prototype.toJSON = function (key) { return this.valueOf(); }; } var cx = /[\u0000\u00ad\u0600-\u0604\u070f\u17b4\u17b5\u200c-\u200f\u2028-\u202f\u2060-\u206f\ufeff\ufff0-\uffff]/g, escapable = /[\\\"\x00-\x1f\x7f-\x9f\u00ad\u0600-\u0604\u070f\u17b4\u17b5\u200c-\u200f\u2028-\u202f\u2060-\u206f\ufeff\ufff0-\uffff]/g, gap, indent, meta = { '\b': '\\b', '\t': '\\t', '\n': '\\n', '\f': '\\f', '\r': '\\r', '"': '\\"', '\\': '\\\\' }, rep; function quote(string) { escapable.lastIndex = 0; return escapable.test(string) ? '"' + string.replace(escapable, function (a) { var c = meta[a]; return typeof c === 'string' ? c : '\\u' + ('0000' + a.charCodeAt(0).toString(16)).slice(-4); }) + '"' : '"' + string + '"'; } function str(key, holder) { var i, k, v, length, mind = gap, partial, value = holder[key]; if (value && typeof value === 'object' && typeof value.toJSON === 'function') { value = value.toJSON(key); } if (typeof rep === 'function') { value = rep.call(holder, key, value); } switch (typeof value) { case 'string': return quote(value); case 'number': return isFinite(value) ?

'[]' : gap ?

': ' : ':') + v); } } } } else { for (k in value) { if (Object.hasOwnProperty.call(value, k)) { v = str(k, value); if (v) { partial.push(quote(k) + (gap ?

'{\n' + gap + partial.join(',\n' + gap) + '\n' + mind + '}' : '{' + partial.join(',') + '}'; gap = mind; return v; } } if (typeof JSON.stringify !== 'function') { JSON.stringify = function (value, replacer, space) { var i; gap = ''; indent = ''; if (typeof space === 'number') { for (i = 0; i < space; i += 1) { indent += ' '; } } else if (typeof space === 'string') { indent = space; } rep = replacer; if (replacer && typeof replacer !== 'function' && (typeof replacer !== 'object' || typeof replacer.length !== 'number')) { throw new Error('JSON.stringify'); } return str('', { '': value }); }; } if (typeof JSON.parse !== 'function') { JSON.parse = function (text, reviver) { var j; function walk(holder, key) { var k, v, value = holder[key]; if (value && typeof value === 'object') { for (k in value) { if (Object.hasOwnProperty.call(value, k)) { v = walk(value, k); if (v !== undefined) { value[k] = v; } else { delete value[k]; } } } } return reviver.call(holder, key, value); } text = String(text); cx.lastIndex = 0; if (cx.test(text)) { text = text.replace(cx, function (a) { return '\\u' + ('0000' + a.charCodeAt(0).toString(16)).slice(-4); }); } if (/^[\],:{}\s]*$/.test(text.replace(/\\(?:["\\\/bfnrt]|u[0-9a-fA-F]{4})/g, '#').replace(/"[^"\\\n\r]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g, ']').replace(/(?:^|:|,)(?:\s*\[)+/g, ''))) { j = eval('(' + text + ')'); return typeof reviver === 'function' ? walk({ '': j }, '') : j; } throw new SyntaxError('JSON.parse'); }; } } ());
