I am trying to fill my FullCalendar with events using json. But I get an error when trying to load such events. Since I am new to all of this I was trying to load just a single event and I am not even getting the info from a database for now.
$('#calendar').fullCalendar({
defaultView: 'agendaWeek',
theme:true,
allDaySlot: false,
allDayText: false,
minTime: 7,
maxTime: 19,
events: {
url: 'JornadasDeportivas.php',
type: 'POST',
data: {
opcion: 'eventos',
},
error: function() {
alert('Error al cargar los eventos');
}
}
});
My php code is just calling this method
function json(){
echo '
[
{
"title" : "event1",
"allDay" : false,
"start" : "2011-09-09 12:30:00",
"end" : "2011-09-09 15:30:00"
}
]
';
}
and the output is
[ { "title" : "event1", "allDay" : false, "start" : "2011-09-09 12:30:00", "end" : "2011-09-09 15:30:00" } ]
and I always get the error alert. I don't know what I'm doing wrong.Pleeeeaseee help!!! :( Thanks in advance!
as it was said there should be no comma after " opcion: 'eventos' ", last objects attribute (and that also goes for fields in array) should not be followed comma. Most of browsers dont really care about it (for me Chrome/FF are just ignoring it), but IE (at least version 7 I use for some checks) shows an error.
Another problem you can be facing is that your headers are not set correctly. For proper json reading some browser require response with strict "application/json" header, but for IE7 (dont have 8+ so cant say for those for sure) you need to return "text/plain".
There also could be some problem with timeFormat you use, at least in documentation in timeFormat section they show an event time in "2010-01-01T14:30:00" format, so try putting "T" instead of space.
In your case, I would build an event object as normaly php array, set proper header and display it with json_encode function.
I'm not sure but is it the comma after opcion: 'eventos',

So I have the jQuery datatable using AJAX to call for the JSON in this format.
$(document).ready(function () {
$('#test').DataTable({
ajax:{
url:"players.json",
dataSrc:""
},
columns: [
{data: "id"},
{ data: "player" },
{ data: "points" },
{ data: "steals" },
{ data: "blocks" },
{ data: "assists" },
{ data: "MPG" },
{ data: "shot %" },
{ data: "3 %" }
]
});
});
My aspx.cs file has a method to create the JSON file which works.
[System.Web.Services.WebMethod]
public static void loadTable()
{
NBAPlayerRepository players = new NBAPlayerRepository();
DataTable dt = players.GetAll();
var json = dt.ToJson();
System.IO.File.WriteAllText(#"C:\Users\wheres\Downloads\nbaStats\nbaStats\nbaStats\players.json", json);
}
And the JSON looks like this:
[{"id" : "67926aa7-46b7-4418-96db-fc7e5216aac4","playername" : "Wilson Heres","points" : "34534","steals" : "34","blocks" : "34","assists" : "343","mpg" : "343","shootingpercentage" : "33.3429985046387","threepointpercentage" : "33.3429985046387"}
,{"id" : "6dc42e0b-8750-463d-a9ef-5a025a27154b","playername" : "Wilson Heres","points" : "34534","steals" : "34","blocks" : "34","assists" : "343","mpg" : "343","shootingpercentage" : "33.3429985046387","threepointpercentage" : "343.334014892578"}
,{"id" : "f727130c-5b94-4730-a653-cfb603c73b8a","playername" : "Wilson Heres","points" : "34534","steals" : "34","blocks" : "34","assists" : "343","mpg" : "343","shootingpercentage" : "33.3429985046387","threepointpercentage" : "343.334014892578"}
]
But now I am getting this error "jquery.dataTables.min.js:48 Uncaught TypeError: Cannot read property 'length' of undefined"
Edit: This all works now. Just had to add dataSrc:""
Cleaned-up version of your DataTables initialization
$(document).ready(function () {
$('#test').DataTable({
ajax: {
url: "players.aspx/loadTable"
},
columns: [
{ data: "id" },
{ data: "player" },
{ data: "points" },
{ data: "steals" },
{ data: "blocks" },
{ data: "assists" },
{ data: "MPG" },
{ data: "Shot %" },
{ data: "3 %" },
]
});
});
This may seem like a lot of stuff was removed from your code, so let me make some explanations/assumptions about what was changed.
Assumptions
First, an assumption: DataTables will always try to use a GET request, not a POST when first getting the data from the table, so make sure that your data processing code expects that.
I also am assuming that you have no strong desire to have your Ajax separate from your initialization and that was just how you decided to do it as a first attempt. If that is the case, let me know and I'll update the code to match that.
Explanation
Your formatting is incorrect in some areas and against DataTables standard in others, so this version should do most of what you were trying to do in a much simpler form. A lot of your Ajax options are unnecessary because they are already the default (JSON for the data type, for example), which is why they have been removed.
One nice thing about DataTables is that you can have the Ajax options in the initialization, which is what I have done here. You do lose the success and failure callbacks but I think that for debugging purposes they aren't really necessary and having any extra code increases the amount of stuff to debug (I don't even use those callbacks in most of my final code).
Most of the other changes were mainly incorrect nomenclature (e.g. data instead of title in the column definitions.
Disclaimer
While I would recommend these changes in general just to improve your code, I would make sure to take a look at the format of the JSON that is being sent to and from the server. If you don't know how to do that I'd recommend downloading Fiddler to 'listen in' on the JSON data being sent.
If your JSON is wrong, no amount of changes to the page are going to make the table appear.
Finally, make sure you have no JS errors on the page. Use your browser's developer console (F12) to check that.
If you do find any JS errors, post them in your question. I'd also recommend posting the JSON data being sent to the question as well so that we can ensure the format is correct.
I have a use case where I would like to have jqGrid display some raw JSON for a particular column. I have the following JSON being sent from the server:
{"items":[
{
"code":"ABC123",
"description":"",
"custom_data":{"items":[
{"prop1":"val1","prop2":"val2"},
{"prop1":"val3","prop2":"val4"}
]}
},
{"code":"ABC124","description":"","custom_data":[]},
...,
]}
and a jqGrid configuration like so:
{
url:'/api/somewhere',
datatype: "json",
jsonReader : {
root:"items",
repeatitems: false,
id: "code"
},
colNames:['Code',
'Description',
'Data',],
colModel:[
{
name:'code', index:'code', width:100, hidden:false,
edittype:'text',
editable: true,
editrules:{required:true, edithidden:true},
editoptions: {readonly:false}
},
{
name:'description',
index:'description',
width:250,
editable:true,
edittype:'text',
editrules:{required:true}
},
{
name:'custom_data',
index:'custom_data',
width:100,
hidden:true,
sortable:false,
editable:true,
edittype:'text',
editrules:{required:false, edithidden:true}
},
],
...,
The grid displays OK, but the custom_data column is displayed as [object Object]. What I need is for it to display the raw JSON string I have tried calling JSON.stringify on the custom_data object for each row object using the loadComplete event, but that didn't work. I need to do some data manipulation after the GET anyway, as I want to delete null values from the custom_data object.
My users are comfortable reading and editing raw JSON, so I also need the add/edit form to accept raw JSON which will then get POSTed.
I'm not sure if I'm simply using the wrong event to convert the object back to a string, or if there is something else going on.
What you can do is usage of custom formatter for "custom_data" column
formatter: function (cellValue, options, rawData) {
return cellValue.items ? JSON.stringify(cellValue.items) : "";
}
I changed in the demo hidden property for "custom_data" column to true to see the data
Additionally you can consider to use userdata instead of hidden column to save additional custom data. I recommend you to read the answer additionally which shows not only how to use userdata, but additionally how to show additional data in form subgrid.
I just working with JSON data and am playing around with jQuery and Ajax requests. Pretty basic stuff, but here's my problem.
I have a basic data set which I was using for time tracking. I know how to parse the simple JSON data like this:
{
"end" : "1/18/2011",
"start" : "1/18/2011",
"task" : "Code Review",
},
It's the more complicated stuff I'm trying to parse like this where I'm trying to pull the "time" data out.
{
"end" : "1/17/2011",
"start" : "1/17/2011",
"task" : "Exclusive Brands",
"time" : {
"analysis" : 4,
"documentation" : 3,
"meetings" : 2
}
This is the code for the script I've been using to parse the simple data:
$(function() {
$('.load').click(function(){
$.getJSON("data.js",function(data){
$.each(data.timesheet, function(i,data){
var div_data ="<div class='box'>"+data.start+" "+data.task+"</div>";
$(div_data).appendTo("#time-tracking");
});
}
);
return false;
});
});
My question is what's the format to parse the time data, or what's the best way to parse the information nested inside the time element?
Any help will be greatly appreciated.
A JSON string will be parsed into an object. When parsed, the time is the key of one object. You could retrieve the value of this object through the dot operator (.).
data = JSON.parse('{"end":"1/17/2011", "start":"1/17/2011", "task":"Exclusive Brands", "time": {"analysis":4, "documentation":3, "meetings":2 } }')
// => obj
data.time.analysis
// => 4
In your case similarly you could use the data.time.meetings to access your data from remote server.
Unless I am terribly mistaken, since jquery already converted data into a javascript for you, you should be able to access time as if it was a javascript object like so:
var analysis = data.time.analysis;
var documentation = data.time.documentation;
var meetings = data.time.meetings;
etc...
I found the very nice demo by Oleg (http://www.ok-soft-gmbh.com/jqGrid/FillToolbarSearchFilter.htm) which shows a "jqGrid toolbar search with autocomplete using local data" but have trouble to get this to work for json via ajax. Is there a good reason why the autocomplete feature won't work - even if I force the grid to be local after loading?
$(document).ready(function() {
var mygrid = $("#mylist"),
mygetUniqueNames = function(columnName) {
var texts = mygrid.jqGrid('getCol',columnName), uniqueTexts = [],
textsLength = texts.length, text, textsMap = {}, i;
for (i=0;i<textsLength;i++) {
text = texts[i];
if (text !== undefined && textsMap[text] === undefined) {
// to test whether the texts is unique we place it in the map.
textsMap[text] = true;
uniqueTexts.push(text);
}
}
return uniqueTexts;
};
mygrid.jqGrid({
url:'autocompleteTest.php',
datatype: "json",
colNames:['name', 'City','stateCd'],
colModel:[
{name:'name',index:'name',width:225, search: true},
{name:'City',index:'City',width:125},
{name:'stateCd',index:'stateCd',width:75},
],
rowNum: 100,
loadonce : true,
sortname: 'name',
sortorder: 'desc',
sortable: true,
viewrecords: true,
rownumbers: true,
sortorder: "desc",
ignoreCase: true,
pager: '#mypager',
height: "auto",
caption: "How to use filterToolbar better with data from server"
}).jqGrid('navGrid','#mypager',
{edit:false, add:false, del:false, search:false, refresh:false});
mygrid.jqGrid('setColProp', 'name',
{
searchoptions: {
sopt:['bw'],
dataInit: function(elem) {
$(elem).autocomplete({
source:mygetUniqueNames('name'),
delay:0,
minLength:0
});
}
}
});
mygrid.jqGrid('filterToolbar',
{stringResult:true, searchOnEnter:true, defaultSearch:"bw"});
});
It is difficult to provide an example in case of the usage of remote source parameter of jQuery UI Autocomplete. The main problem is that your question is about jqGrid which is pure JavaScript solution. If we would discuss the server part of tha solution we would have too options. Many users uses different languages: Java, C#, VB, PHP and so on. For example I personally prefer C#. Then we would have to choose the technology which we use: ASP.NET MVC, WCF, ASPX web service and so on. For example I would choose WCF. Then we should define the database access technology, for example, Entity Framework, LINQ to SQL, SqlDataReader, SqlDataAdapter and so on. Let us I would choose Entity Framework and would provide you the corresponding code example, but it would help you not really if you use for example PHP and MySQL.
So I just describe which interface should have the server for the remote source parameter of jQuery UI Autocomplete without any code.
You should replace in my example the source parameter to your server url like following:
dataInit: function(elem) {
$(elem).autocomplete({
source:'yourSearchUrl.php',
minLength:2
});
}
If the user types two characters (the value can be changed by minLength option), for example 'ab' then the autocomplete will make HTTP GET request with the parameter term=ab:
yourSearchUrl.php?term=ab
your server should answer with the JSON data in the same format as for the local source. I used the string array format in my previous example. Another supported format is array of objects with label/value/both properties like
[
{
"id": "Dromas ardeola",
"label": "Crab-Plover",
"value": "Crab-Plover"
},
{
"id": "Larus sabini",
"label": "Sabine`s Gull",
"value": "Sabine`s Gull"
},
{
"id": "Vanellus gregarius",
"label": "Sociable Lapwing",
"value": "Sociable Lapwing"
},
{
"id": "Oenanthe isabellina",
"label": "Isabelline Wheatear",
"value": "Isabelline Wheatear"
}
]
read the documentation for more information.
If you need to implement more complex scenario and send some additional data to the server or convert the server response in any way you can use custom source callback function. In the case you should use source: function(request, response) {/*your implementation*/}, where the request would be an object having term property (request.term). Inside of your implementation your should make ajax request to the server manually. The response would be callback function which you should call after your custom ajax request will be finished (inside of success event handler). The response function should be called with the parameter which should be array in the same format as mygetUniqueNames returns. I recommend you to examine the source code from the jQuery Autocomplete demo.
To de able to provide unique data from one column of tabele you should just use SELECT DISTINCT SQL statement which are supported in the most databases.
I hope that my description would help you.
UPDATED: If you have the local source the solution you could find in my old answer which you already use. What you just need to do is to call the filterToolbar after the source array are filled. Because you load the data from the server your should move the call of filterToolbar inside of loadComplete. You use loadonce:true jqGrid option which switch the datatype from 'json' to 'local' after the first data loading. So you can include in the loadComplete event handler of your grid the code like the following:
var grid = $('#list');
grid({
url:'autocompleteTest.php',
datatype: 'json',
loadonce: true,
// ... other parameters
loadComplete: function(data) {
if (grid.getGridParam('datatype') === 'json') {
// build the set 'source' parameter of the autocomplete
grid.jqGrid('setColProp', 'name', {
searchoptions: {
sopt:['bw'],
dataInit: function(elem) {
$(elem).autocomplete({
source:mygetUniqueNames('name'),
delay:0,
minLength:0
});
}
}
});
mygrid.jqGrid('filterToolbar',
{stringResult:true,searchOnEnter:true,
defaultSearch:"bw"});
}
}
});
If you will need to reload the data from the server (change the datatype to 'json' and call grid.trigger('reloadGrid')) you will have to change the code above so that you first destroy the autocomplete widget with $('#gs_name').autocomplete('destroy') and then create it one more time with the same code like inside of dataInit.
Whats wrong in below JSON Object definition
I am trying to create a new JSON Object like below.
So that my idea is to access COMPANYSETUP.HourSetup.initiate();
Not sure the error ?
COMPANYSETUP = {
initiated : false,
companyId : "",
initiate : function() {
if(!initiated){
// TO DO
initiated = true;
} },
HourSetup = {
initiated : false,
hourId : "",
initiate : function() {
if(!initiated){
// TO DO
initiated = true;
}
}
}
};
Assuming you want a javascript object and not JSON, which disallows functions,
HourSetup =
Should be changed to:
HourSetup :
Also, as JonoW points out, your single line comments are including some of your code as the code is formatted in the post.
There's a "=" that shouldn't be there. Change it to ":"
JSON is a form of JavaScript deliberately restricted for safety. It cannot include dangerous code elements like function expressions.
It should work OK in plain eval()ed JavaScript, but it's not JSON.
