Jquery :: GetJSON() Assigning JSON Returned To An Array/var Outside Callback Function?
Oct 12, 2010
I'm trying to assign the values from the JSON data returned when I run this code into an array that's outside the callback function. The data is multidimensional, and I have been able to use this data within the callback function. However I want to use it outside that function. i.e. the jsdata returned in the code below is to be used outside the function
Code:
$.getJSON('../fxns/status.php',function(jsdata){
//do some stuff with JSON data or pass to global variable[code]..........
I am trying out $.ajax instead of getJSON for debugging purposes. Because getJSON did not report an error in IE (6,7 or 8) and I am trying to figure out why a jQuery plug-in is not painting my returned images to the screen in IE but is in other browsers. So I tried this. Interestingly enough, it hits the error event in IE but not firefox, safari and the rest and I don't know why (this code works great and renders my data just fine in FireFox and the rest). I know my returned json is valid:
I don't know what else to do to troubleshoot why IE is having so much trouble with the returned JSON or just executing the function(data) using either getJSON OR this. I have set the headers not the cache also in the response. IE refuses to enter my function(data) on the response.
Same result. Firefox and the rest had no issue. IE still exited the $.ajax and my error method kicked in. No rhyme or reason whatsoever and I tried the IE Dev tools... nothing. About the only thing I get is this: Line: 163 Error: System error: -1072896658.Line 163 which is simply the line: function() { alert("An error has occurred. try again."); This has got to be the most f*d up situation I've been in and I need to get this working! I just cannot understand why IE can't parse a getJSON or $.ajax response, that is impossible or else there would be a huge meltdown with jQuery.
I'm trying to execute a simple JSON request using getJSON but I can't get a successful response. My code is below. If I run this I always receive an error. If I add "callback?" (making it JSONP) then I can see the correct results in Firebug but the call back function is never executed. function getResults(url) { var gptUrl = "[URL]"; $.getJSON(url, {f: "json"}, function() { alert("success"); }) .success(function() { alert("second success"); }) .error(function() { alert("error"); }) .complete(function() { alert("complete"); });}
I'm having troubles with an existing J2EE application (which uses Dojo) and in which I'm gradually introducing jQuery. The specific issue is with the malsup Form plugin and the JSON returned from a form submission: the error callback is always called, regardless of what happens on the server side, and the error is always "parsererror". I'm using jQuery 1.4.2 and the 2.45 version of the malsup Form plugin. For example, given the following code:
$(document).ready(function() { var options = { dataType: 'json',[code]....
the server receives the submission and handles it without errors, then in the browser I always get the same alert from the processAddressEditSubmitError() function, with an "Invalid JSON" message:
I use the getJSON request to fill a select (with cities names) after the user have choosen his region.
I paste some code:
The problem is that callback is never called. I used firebug and i have seen that when i change region the getJSON function is called and my script (python) return this JSON:
Why my callback is not called? I can't even get the alert ('callback time!'). I thinked that my json could be broken, but firebug net console read and parse it very well, so i think is valid JSON.
I also tried to split up the function declaration from the getJSON request, but it's no use.
I am using a json from a Google spreadsheet and a jquery plugin which is called throught this HTML line <ul id="example">.The thing is that when I dynamically append elements to the <ul id="example"> from within the JSON callback function, these are not recognized by the jquery plugin
Code:
<form> <ul id="example">BLA BLA BLA</ul> </form>
[code]....
If I insert an <ul id="example"> plus some <li> in the HTML code the plugin works perfect If I insert dynamically some <li> to the <ul id="example"> throught a javascrypt function before executing the callback (...json-in-script&callback=...) also work perfect.But when I insert dynamically the <li> elements within the callback function (in my case: cm_loadMapJSON) does not work well.
i am doing an application which make use of JQuery and Cakephp . In this i am using like the following to retrieve the values from my controller side
var getformid; $.getJSON("http://localhost/FormBuilder/index.php/forms/getFormEntry", function(json) { getformid=json.forms[0]["id"];
[code]....
In the above code, the inner alert that is inside $.getJSON gives me the correct value as 75 But the outer alert showing me the error as getformid not defined..Why so??Can't we make use of the getformid available outside $.getJSON .Please suggest me.SInce i want to make use of that value for saving the Field ..
The autocomplete (I'm using this one) and the getJSON work perfectly. The problem comes when I try to do something with the returned json data. Line 14 won't work for me. Any selectors I try on the returned json data won't work. The selectors still work on items that were there before the json data was returned.
I have setup a little example here: [URL] It is JSONP because of cross site policy. The returned JSON is valid, you can check the response in firebug. The callback function is not fired.
Tested with jquery 1.3.2, 1.4.2 and 1.4.4. Same result.
I'm doing some cross domain JSON requests and I'm unable to use query strings on my webservice calls (similar to codeignitor requests but without the work-arounds, qs params are entirely off the table). Is there another way I can format the callback variable to the url request?
I'm using getJSON to load data from the database onto a form. How can I specify the success & error callbacks? here's the code I'm using: EDIT: I managed to get the success callback by adding it below the $('fontSize')... but how can I set the error callback?
I am trying to get the latitude and longitude from a json structure which i got over this google maps geoencode api (v3) - 2 addresses -> it looks like this....
Every parse example I have seen on the internet is the well formed;
jQuery.parseJSON( ' {"sid":"123455","client_id":"1","last_name":"Anderson","first_name":"Alan","institution_id":"1"} '); What is the easy way to get from this; {"posts":[{"post":
I have used getSON() successfully before but I am meeting with an issue which I don't seem to get a hold on. The data object returned is not populated correctly by getJSON(). Am I doing something wrong?
I have a java object array. I am using java 1.4. The object has attributes with getters/setters.I tried JSON-simple API to convert the array to string. This outputs error JSON string
I'm trying to parse a Json string received by $.getJSON(). I can receive the string but firebug gives me an "invalid label" error. I think it is because the string is an hash array with a number as first label, but I'm not sure. This is the string:
{"15":{"id":15,"x":0.4589937586135409,"y": 0.8324914620560137,"z":-0.9435707004102728,"rawData":"1256204002860 13 -442866538 18392602 647462767 314 1777206957 -1664784174 "}} and this is the non-working code:
The below code posts a couple of vars to a php file which sends back a json object containing (in the test case) one object called 'faves' with 2 variables (let's say called var1 and var2). I can't seem to access the variables after the ajax call. The result is always an 'undefined' error message. I've tried:
I've been hitting a strange bug where callbacks are not invoked when a JSON response is returned from an AJAX call under jQuery 1.4.1. I just upgraded my app; this was working perfectly pre-1.4.
I do specify the return type as "json" when I invoke $.post . When a simple JSON string like "false" is returned, the callback is invoked. It seems to fail with more complex types, specifically with JSON objects, i.e., {"a":1, "b":5} .
If it helps, I'm running Firefox 3.5 on Ubuntu. In my test environment, the only installed extension is Firebug.
I'm pretty new to jQuery and I'm using $.getJSON to submit some data to a PHP script which either returns 5 sets of json-formatted data or data to indicate an error condition (i.e., no data available) from the PHP database query. The callback routine handles the 5 sets of json-formatted data just fine (using $.each...) but I'm having trouble testing for either just a string with 'null' in it or a json-formatted data return of [{"error":"null"}].
My callback code for the second approach looks like this: function handle_stores(data) { if (data.error == "null") ..... But this test does not execute the following code for the 'true' condition, i.e., data.error == "null" never evaluates to 'true'.
I am looking for a solution for many days: my callback - function works well in firefox 5, IE8, but not in safari, opera, IE7 etc. The function "checken" is not executed. There are no error messages in the debugger of safari or IE7.
var session_id = $.cookie("fe_typo_user"); function checken (nummer){ var elem = "#img" + nummer; $(elem).attr('checked',true); } var url = "refreshCheckboxes.php?id=" + session_id; $.getJSON(url,function(data){ $.each(data.posts, function(i,data){ checken (data.number); }); });
The response of the script: {"posts": [{"number":"1325"},{"number":"1303"},{"number":"1302"}]} html (example): <input type="checkbox" id="img1325" class="merkzettel" name="merkzettel1325" value="img_1325.jpg" />
You can test it here: [URL]. Activate some checkboxes, load another site and then go back to this site and the checkboxes you have selected, must be activated by the script.
Im trying to validate a form (easy) and POST it to a third party WCF service. I am able to validate and POST data to the service, but its returned data (in table format) keeps opening in a blank page with their url in the browser address bar. Can't have that, I need to grab the returned data and .append it to a div on my page. Here is what I have that FAILS
<script type="text/javascript"> $(document).click(function() { //cancel form
