A complex question :
I've got this code (not the complete code, but the essentials for the question, I think) :
var $pmm:String;
var $pms:String;
var $bmm:String;
var $bms:String;
function get haute1():String { return $pmm; };
function get haute2():String { return $pms; }
function get basse1():String { return $bmm; };
function get basse2():String { return $bms; };
accueil.todayHaute_txt.htmlText = haute1;
accueil.todayBasse_txt.htmlText = basse1;
accueil.todayHauteSecond_txt.htmlText = haute2;
accueil.todayBasseSecond_txt.htmlText = basse2;
"haute1" is an hour (in 24h format). Something like "13h25".
It changes everyday.
Question : How can put them in ascending order in AS3 ?
Example : If haute1 = 15h20, haute2= 6h00, basse1= 11h and basse2 = 17h, the function would put them in this order :
"haute2", then "basse1", then "haute1" and finally "basse2".
Thx
EDIT
I add this code that I have. is it helping you ?
/ Assigns hours and tidal heights
$pmm = convdateheure($tpbs[1 + $deltapm]);
$pms = convdateheure($tpbs[3 + $deltapm]);
$bmm = convdateheure($tpbs[2 - $deltapm]);
$bms = convdateheure($tpbs[4 - $deltapm]);
function convdateheure($valeur:Number):String
{
var $heure:Number = Math.floor($valeur);
var $minute:Number = Math.floor(Math.floor(($valeur - Math.floor($valeur)) * 100) * 0.6);
var hoursLabel:String = "", minsLabel:String = "";
if ($heure == 24) $heure = 0; // Check if at the 24 hour mark, change to 0
if ($heure < 10) hoursLabel += "0" + $heure.toString(); else hoursLabel = $heure.toString();
if ($minute < 10) minsLabel += "0" + $minute.toString(); else minsLabel = $minute.toString();
return hoursLabel + ":" + minsLabel;
}
If you want to order some dates written in some String format:
One way would be, depending on you date string format, just to push them into array and sort them as strings, then read them all.
Another way would be to first parse those strings into Date instances, and push their Date.time property to array, sort it, then do reverse: parse all time values from sorted array into new Date instances then use Date.toString or similar.
Assuming that $valuer is a numerical value:
var timesArray:Array = new Array();
var convertedTimesArray:Array = new Array();
function sortTimes():void{
timesArray.push($valuer);
timesArray.sort(Array.NUMERIC);
}
function convertTimes():void{
convertedTimesArray = []; // clear the array
for (var i:int = 0; i < timesArray.length; i++){
var s:String = convdateheure(timesArray[i]);
convertedTimesArray.push(s);
}
}
That should give you one array of actual times, sorted in numerical order, and one array sorted in the same numerical order, but converted to String values using your function.
I have just recentely used AngularJS to "convert" a data structure I had in pure SVG format into JSON format.
Now, I want to store such a structure in a MongoDB database to start finally connecting some components of the MEAN stack together and start seeing some things working! Basically, I have the following code inside a Webstorm AngularJS project:
JS:
var app = angular.module('app', []);
var RectangleDim=30;
app.controller('MainCtrl', function($scope) {
$scope.graph = {'width': 5000, 'height': 5000};

];
$scope.draw=function(val)
{
// val = document.getElementById("NumQuest").value;
return JSON.parse('{\"cx\":'+val+', "cy": 20, "r":30}');
// $scope.circles.push(JSON.parse('{\"x\":'+val+', "y": 220, "r":30}'));
};

The relevant part of the code is the $scope.rectangles array which contains the JSON.parse of the strings representing my data structure on the html side and that structure in JSON (or JSON parsed or whatever) is what I want to save in the MongoDB database...How can I do that? The HTML relevant part is just like this:
HTML:
<p><button ng-click="DrawMatrixEvenProgression(NumQuest)">Draw</button></p>
<svg ng-attr-height="{{graph.height}}" ng-attr-width="{{graph.width}}">
<rect ng-repeat="rect in rectangles"
ng-attr-x="{{rect.x}}"
ng-attr-y="{{rect.y}}"
ng-attr-width="{{rect.width}}"
ng-attr-height="{{rect.height}}">
</rect>
</svg>
Any help will be appreciated... Can I start by adding more files to that project to handle the database and then things will be linked together?
Like adding stuff to handle the mongoose and the connections?
Thanks in advance!
Because Angular is a front-end framework. So to communicate with database (in this case MongoDB) you need to have application on the server-side to handle this and I suggest you to use Node.js and Mongoose as a MongoDB driver.
Node.js
Mongoose
Come back to Angular, you can create Angular service or factory and let the them talk to your server with service like $http or $resource.
Angular service documentation
Example for angular service
angular.module('app')
.factory('RectangleService', function($http){
return {
create: create
}
function create(rectangle){
// make http request to the server
return $http({
url: 'API_URL',
method: 'GET',
params: rectangle
});
}
});
After you create your service you have to inject it to your controller and
you may create some function to your $scope to talk with service like this
app.controller('MainCtrl', function($scope, RectangleService) { // <-- Inject service to controller
// your controller code
$scope.createRectangle = function(rectangle){
RectangleService.create(rectangle);
}
});
You can map createRectangle function to directive like ng-click and pass your json data as a parameter
Because I don't know what server-side language you can use, so I don't come with an example for Node.js & Mongoose
Hope this can help :)
I want to bind my ng-model with JSON object nested key where my key is in a variable.
var data = {"course":{"sections":{"chapter_index":5}}};
var key = "course['sections']['chapter_index']"
Here I want to get value 5 from data JSON object.
I found the solution to convert "course.sections.chapter_index" to array notation like course['sections']['chapter_index'] this. but don't know how to extract value from data now
<script type="text/javascript">
var BRACKET_REGEXP = /^(.*)((?:\s*\[\s*\d+\s*\]\s*)|(?:\s*\[\s*"(?:[^"\\]|\\.)*"\s*\]\s*)|(?:\s*\[\s*'(?:[^'\\]|\\.)*'\s*\]\s*))(.*)$/;
var APOS_REGEXP = /'/g;
var DOT_REGEXP = /\./g;
var FUNC_REGEXP = /(\([^)]*\))?$/;
var preEval = function (path) {
var m = BRACKET_REGEXP.exec(path);
if (m) {
return (m[1] ? preEval(m[1]) : m[1]) + m[2] + (m[3] ? preEval(m[3]) : m[3]);
} else {
path = path.replace(APOS_REGEXP, '\\\'');
var parts = path.split(DOT_REGEXP);
var preparsed = [parts.shift()]; // first item must be var notation, thus skip
angular.forEach(parts, function (part) {
preparsed.push(part.replace(FUNC_REGEXP, '\']$1'));
});
return preparsed.join('[\'');
}
};
var data = {"course":{"sections":{"chapter_index":5}}};
var obj = preEval('course.sections.chapter_index');
console.log(obj);
</script>
Hope this also help others. I am near to close the solution,but don't know how can I get nested value from JSON.
This may be a good solution too
getDeepnestedValue(object: any, keys: string[]) {
keys.forEach((key: string) => {
object = object[key];
});
return object;
}
var jsonObject = {"address": {"line": {"line1": "","line2": ""}}};
var modelName = "address.line.line1";
var result = getDescendantPropValue(jsonObject, modelName);
function getDescendantPropValue(obj, modelName) {
console.log("modelName " + modelName);
var arr = modelName.split(".");
var val = obj;
for (var i = 0; i < arr.length; i++) {
val = val[arr[i]];
}
console.log("Val values final : " + JSON.stringify(val));
return val;
}
You are trying to combine 'dot notation' and 'bracket notation' to access properties in an object, which is generally not a good idea.
Source: "The Secret Life of Objects"
Here is an alternative.
var stringInput = 'course.sections.chapter_index'
var splitInput = stringInput.split(".")
data[splitInput[1]]][splitInput[2]][splitInput[3]] //5
//OR: Note that if you can construct the right string, you can also do this:
eval("data[splitInput[1]]][splitInput[2]][splitInput[3]]")
Essentially, if you use eval on a string, it'll evaluate a statement.
Now you just need to create the right string! You could use the above method, or tweak your current implementation and simply go
eval("data.course.sections.chapter_index") //5
Source MDN Eval docs.
var data = {
"course": {
"sections": {
"chapter_index": 5
}
}
};
var key = "course['sections']['chapter_index']";
var keys = key.replace(/'|]/g, '').split('[');
for (var i = 0; i < keys.length; i++) {
data = data[keys[i]];
}
console.log(data);
The simplest possible solution that will do what you want:
var data = {"course":{"sections":{"chapter_index":5}}};
var key = "course['sections']['chapter_index']";
with (data) {
var value = eval(key);
}
console.log(value);
//=> 5
Note that you should make sure key comes from a trusted source since it is eval'd.
Using with or eval is considered dangerous, and for a good reason, but this may be one of a few its legitimate use cases.
If you don't want to use eval you can do a one liner reduce:
var data = {"course":{"sections":{"chapter_index":5}}};
var key = "course['sections']['chapter_index']"
key.split(/"|'|\]|\.|\[/).reduce((s,c)=>c===""?s:s&&s[c], data)
Hopefully this is easy but that sometimes means its impossible in flex and I have searched quite a bit to no avail.
Say I have a list (LIST#1) of artists:
2Pac
Adele
Amerie
Beyonce
Jason Aldean
Shakira
The Trews
I also have a list (LIST#2) that has the values #,A-Z - how would I create an alphabet jump?
So If a user clicked on "A" in LIST#2 that would automatically scroll to "Adele" at the top of LIST#1 - not filter so he/she could scroll up to view 2Pac or down to view The Tews if they were not in the view yet.
Its a standard Flex Spark List with an ArrayCollection as the dataProvider - the artist field is called: "title" along with a unique id field that is not visible to the user.
Thanks!
Please see comments on marker answer for discussion on Dictionary that may be faster in some cases. See below for code (HAVE NOT CONFIRMED ITS FASTER! PLEASE TEST):
private function alphabet_listChange(evt:IndexChangeEvent) : void {
var letter:String;
letter = evt.currentTarget.selectedItems[0].toString();
trace(currentDictionary[letter]);
ui_lstLibraryList.ensureIndexIsVisible(currentDictionary[letter]);
}
public function createAlphabetJumpDictionary() : Dictionary {
//alphabetArray is a class level array containing, A-Z;
//alphabetDictionary is a class level dictionary that indexes A-z so alphabetDictionary["A"] = 0 and ["X"] = 25
var currentIndexDict:Dictionary = new Dictionary; //Dictionary is like an array - just indexed for quick searches - limited to key & element
var searchArray:Array = new Array;
searchArray = currentArrayCollection.source; //currentArrayCollection is the main array of objects that contains the titles.
var currentIndex:Number; //Current index of interation
var currentAlphabetIndex:Number = 0; //Current index of alphabet
for (currentIndex = 0; currentIndex < searchArray.length; currentIndex++) {
var titleFirstLetter:String = searchArray[currentIndex].title.toString().toUpperCase().charAt(0);
if (titleFirstLetter == alphabetArray[currentAlphabetIndex]) {
currentIndexDict[titleFirstLetter] = currentIndex;
trace(titleFirstLetter + " - " + currentIndex);
currentAlphabetIndex++;
} else if (alphabetDictionary[titleFirstLetter] > alphabetDictionary[alphabetArray[currentAlphabetIndex]]) {
trace(titleFirstLetter + " - " + currentIndex);
currentIndexDict[titleFirstLetter] = currentIndex;
currentAlphabetIndex = Number(alphabetDictionary[titleFirstLetter] + 1);
}
}
return currentIndexDict;
}
private function build_alphabeticalArray() : Array {
var alphabetList:String;
alphabetList = "A.B.C.D.E.F.G.H.I.J.K.L.M.N.O.P.Q.R.S.T.U.V.W.X.Y.Z";
alphabetArray = new Array;
alphabetArray = alphabetList.split(".");
return alphabetArray;
}
private function build_alphabetDictionary() : Dictionary {
var tmpAlphabetDictionary:Dictionary = new Dictionary;
for (var i:int=0; i < alphabetArray.length; i++) {
tmpAlphabetDictionary[alphabetArray[i]] = i;
trace(alphabetArray[i] + " - " + i);
}
return tmpAlphabetDictionary;
}
private function buildCurrentDictionary() : void {
trace("Collection Changed");
currentDictionary = new Dictionary;
currentDictionary = createAlphabetJumpDictionary();
}
The Flex Spark list has a very convenient method called ensureIndexIsVisible(index). Check the Flex reference documentation. All you have to do is to find the index of the first artist for the corresponding selected alphabet letter:
public function findAlphabetJumpIndex():Number
{
var jumpToIndex:Number;
var selectedLetter:String = alphabethList.selectedItem;
for (var i:int=0; i < artists.length; i++)
{
var artistName:String = artists.getItemAt(i);
var artistFirstLetter:String = artistName.toUpperCase().charAt(0);
if (artistFirstLetter == selectedLetter)
{
jumpToIndex = i;
break;
}
}
return jumpToIndex;
}
You can iterate your artist list data provider and check if artist name starts with selected alphabet from list two. When corresponding artist is found, set artist list selected index a value what you get from iterating data.
I'm trying to submit a query using the postal code to my DB whenever the googlemaps viewport center changes. I know that this can be done with reverse geocoding with something like:
google.maps.event.addListener(map, 'center_changed', function(){
newCenter();
});
...
function newCenter(){
var newc = map.getCenter();
geocoder.geocode({'latLng': newc}, function(results, status){
if (status == google.maps.GeocoderStatus.OK) {
var newzip = results[0].address_components['postal_code'];
}
});
};
Of course, this code doesn't actually work. So I was wondering how I would need to change this in order to extract the postal code from the results array.
Thanks
What I've realized so far is that in most cases the ZIPCODE is always the last value inside each returned address, so, if you want to retrieve the very first zipcode (this is my case), you can use the following approach:
var address = results[0].address_components;
var zipcode = address[address.length - 1].long_name;
You can do this pretty easily using the underscore.js libraray: http://documentcloud.github.com/underscore/#find
_.find(results[0].address_components, function (ac) { return ac.types[0] == 'postal_code' }).short_name
Using JQuery?
var searchAddressComponents = results[0].address_components,
searchPostalCode="";
$.each(searchAddressComponents, function(){
if(this.types[0]=="postal_code"){
searchPostalCode=this.short_name;
}
});
short_name or long_name will work above
the "searchPostalCode" var will contain the postal (zip?) code IF
and only IF you get one from the Google Maps API.
Sometimes you DO NOT get a "postal_code" in return for your query.
Alright, so I got it. The solution is a little uglier than I'd like, and I probably don't need the last for loop, but here's the code for anyone else who needs to extract crap from address_components[]. This is inside the geocoder callback function
// make sure to initialize i
for(i=0; i < results.length; i++){
for(var j=0;j < results[i].address_components.length; j++){
for(var k=0; k < results[i].address_components[j].types.length; k++){
if(results[i].address_components[j].types[k] == "postal_code"){
zipcode = results[i].address_components[j].short_name;
}
}
}
}
$.each(results[0].address_components,function(index,value){
if(value.types[0] === "postal_code"){
$('#postal_code').val(value.long_name);
}
});
You can also use JavaScript .find method which is similar to underscore _.find method but it is native and require no extra dependency.
const zip_code = results[0].address_components.find(addr => addr.types[0] === "postal_code").short_name;
This takes only two for loops. The "results" array gets updated once we found the first "type" to be "postal_code".
It then updates the original array with the newly found array set and loops again.
var i, j,
result, types;
// Loop through the Geocoder result set. Note that the results
// array will change as this loop can self iterate.
for (i = 0; i < results.length; i++) {
result = results[i];
types = result.types;
for (j = 0; j < types.length; j++) {
if (types[j] === 'postal_code') {
// If we haven't found the "long_name" property,
// then we need to take this object and iterate through
// it again by setting it to our master loops array and
// setting the index to -1
if (result.long_name === undefined) {
results = result.address_components;
i = -1;
}
// We've found it!
else {
postcode = result.long_name;
}
break;
}
}
}
You can also use this code, this function will help to get zip on button click or onblur or keyup or keydown.
Just pass the address to this function.
use google api with valid key and sensor option removed as it doesn't required now.
function callZipAPI(addSearchZip)
{
var geocoder = new google.maps.Geocoder();
var zipCode = null;
geocoder.geocode({ 'address': addSearchZip }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
//var latitude = results[0].geometry.location.lat();
//var longitude = results[0].geometry.location.lng();
var addressComponent = results[0].address_components;
for (var x = 0 ; x < addressComponent.length; x++) {
var chk = addressComponent[x];
if (chk.types[0] == 'postal_code') {
zipCode = chk.long_name;
}
}
if (zipCode) {
alert(zipCode);
}
else {
alert('No result found!!');
}
} else {
alert('Enter proper address!!');
}
});
}
I use this code to get "Postal code" and "locality", but you can use it to get any other field just changing the value of type:
JAVASCRIPT
var address = results[0].address_components;
var zipcode = '';
var locality = '';
for (var i = 0; i < address.length; i++) {
if (address[i].types.includes("postal_code")){ zipcode = address[i].short_name; }
if (address[i].types.includes("locality")){ locality = address[i].short_name; }
}
I think rather than depending on the index it better checks address type key inside the component. I solved this issue by using a switch case.
var address = '';
var pin = '';
var country = '';
var state = '';
var city = '';
var streetNumber = '';
var route ='';
var place = autocomplete.getPlace();
for (var i = 0; i < place.address_components.length; i++) {
var component = place.address_components[i];
var addressType = component.types[0];
switch (addressType) {
case 'street_number':
streetNumber = component.long_name;
break;
case 'route':
route = component.short_name;
break;
case 'locality':
city = component.long_name;
break;
case 'administrative_area_level_1':
state = component.long_name;
break;
case 'postal_code':
pin = component.long_name;
break;
case 'country':
country = component.long_name;
break;
}
}
places.getDetails( request_details, function(results_details, status){
// Check if the Service is OK
if (status == google.maps.places.PlacesServiceStatus.OK) {
places_postal = results_details.address_components
places_phone = results_details.formatted_phone_number
places_phone_int = results_details.international_phone_number
places_format_address = results_details.formatted_address
places_google_url = results_details.url
places_website = results_details.website
places_rating = results_details.rating
for (var i = 0; i < places_postal.length; i++ ) {
if (places_postal[i].types == "postal_code"){
console.log(places_postal[i].long_name)
}
}
}
});
This seems to work very well for me, this is with the new Google Maps API V3. If this helps anyone, write a comment, i'm writing my script as we speak... so it might change.
Using JSONPath, it's easily done with one line of code:
var zip = $.results[0].address_components[?(#.types=="postal_code")].long_name;
In PHP I use this code. Almost in every conditions it works.
$zip = $data["results"][3]["address_components"];
$zip = $index[0]["short_name"];
Romaine M. — thanks! If you just need to find the postal code in the first returned result from Google, you can do just 2 loops:
for(var j=0;j < results[0].address_components.length; j++){
for(var k=0; k < results[0].address_components[j].types.length; k++){
if(results[0].address_components[j].types[k] == "postal_code"){
zipcode = results[0].address_components[j].long_name;
}
}
}
In a word, that's a lot of effort. At least with the v2 API, I could retrieve those details thusly:
var place = response.Placemark[0];
var point = new GLatLng(place.Point.coordinates[1], place.Point.coordinates[0]);
myAddress = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.Thoroughfare.ThoroughfareName
myCity = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.LocalityName
myState = place.AddressDetails.Country.AdministrativeArea.AdministrativeAreaName
myZipCode = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.PostalCode.PostalCodeNumber
There has got to be a more elegant way to retrieve individual address_components without going through the looping jujitsu you just went through.
This simple code works for me
for (var i = 0; i < address.length; i++) {
alert(address[i].types);
if (address[i].types == "postal_code")
$('#postalCode').val(address[i].long_name);
if (address[i].types == "")
$('#country').val(address[i].short_name);
}
Using Jquery
You cant be sure in which location in the address_components array the postal code is stored. Sometimes in address_components.length - 1 > pincode may not be there. This is true in "Address to latlng" geocoding.
You can be sure that Postal code will contain a "postal_code" string. So best way is to check for that.
var postalObject = $.grep(results[0].address_components, function(n, i) {
if (n.types[0] == "postal_code") {
return n;
} else {
return null;
}
});
$scope.query.Pincode = postalObject[0].long_name;
return $http.get('//maps.googleapis.com/maps/api/geocode/json', {
params: {
address: val,
sensor: false
}
}).then(function (response) {
var model= response.data.results.map(function (item) {
// return item.address_components[0].short_name;
var short_name;
var st= $.each(item.address_components, function (value, key) {
if (key.types[0] == "postal_code") {
short_name= key.short_name;
}
});
return short_name;
});
return model;
});
//autocomplete is the text box where u will get the suggestions for an address.
autocomplete.addListener('place_changed', function () {
//Place will get the selected place geocode and returns with the address
//and marker information.
var place = autocomplete.getPlace();
//To select just the zip code of complete address from marker, below loop //will help to find. Instead of y.long_name you can also use y.short_name.
var zipCode = null;
for (var x = 0 ; x < place.address_components.length; x++) {
var y = place.address_components[x];
if (y.types[0] == 'postal_code') {
zipCode = y.long_name;
}
}
});
It seems that nowadays it's better to get it from the restful API, simply try:
https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&key=YOUR_KEY_HERE
Using an AJAX GET call works perfect!
Something like:
var your_api_key = "***";
var f_center_lat = 40.714224;
var f_center_lon = -73.961452;
$.ajax({ url: "https://maps.googleapis.com/maps/api/geocode/json?latlng="+f_center_lat+","+f_center_lon+"&key="+your_api_key,
method: "GET"
})
.done(function( res ) { if (debug) console.log("Ajax result:"); console.log(res);
var zipCode = null;
var addressComponent = res.results[0].address_components;
for (var x = 0 ; x < addressComponent.length; x++) {
var chk = addressComponent[x];
if (chk.types[0] == 'postal_code') {
zipCode = chk.long_name;
}
}
if (zipCode) {
//alert(zipCode);
$(current_map_form + " #postalcode").val(zipCode);
}
else {
//alert('No result found!!');
if (debug) console.log("Zip/postal code not found for this map location.")
}
})
.fail(function( jqXHR, textStatus ) {
console.log( "Request failed (get postal code via geocoder rest api). Msg: " + textStatus );
});
As I got it zip is the last or the one that before last.
That why this is my solution
const getZip = function (arr) {
return (arr[arr.length - 1].types[0] === 'postal_code') ? arr[arr.length - 1].long_name : arr[arr.length - 2].long_name;
};
const zip = getZip(place.address_components);
i think this is the most accurate solution:
zipCode: result.address_components.find(item => item.types[0] === 'postal_code').long_name;
Just search for postal_code in all types, and return when found.
const address_components = [{"long_name": "2b","short_name": "2b","types": ["street_number"]}, { "long_name": "Louis Schuermanstraat","short_name": "Louis Schuermanstraat", "types": ["route"]},{"long_name": "Gent","short_name": "Gent","types": ["locality","political" ]},{"long_name": "Oost-Vlaanderen","short_name": "OV","types": ["administrative_area_level_2","political"]},{"long_name": "Vlaanderen","short_name": "Vlaanderen","types": ["administrative_area_level_1","political"]},{"long_name": "België","short_name": "BE","types": ["country","political"]},{"long_name": "9040","short_name": "9040","types": ["postal_code"]}];
// address_components = results[0]address_components
console.log({
'object': getByGeoType(address_components),
'short_name': getByGeoType(address_components).short_name,
'long_name': getByGeoType(address_components).long_name,
'route': getByGeoType(address_components, ['route']).long_name,
'place': getByGeoType(address_components, ['locality', 'political']).long_name
});
function getByGeoType(components, type = ['postal_code']) {
let result = null;
$.each(components,
function() {
if (this.types.some(r => type.indexOf(r) >= 0)) {
result = this;
return false;
}
});
return result;
}
