JQuery :: JSON Returned From Php?

Apr 4, 2011

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":

JQuery :: .Post() - Accessing The Returned Json Object?

Sep 28, 2010

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:

console.log(data.var1)console.log(data.faves.var1)
console.log(var1)

All to no avail. Can anyone tell me what I'm doing wrong here? I have checked with FireBug that all the data returned is good and well-formed etc.

$(function() {
$.post("<? echo base_url(); ?>test.php", {
id: "<?php echo $id; ?>",

[code]....

JQuery :: IE (any Version) Is Not Parsing Returned JSON Via GetJSON Or $.ajax Calls?

Jul 6, 2009

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:

$.ajax({
type: "GET",
url: "http://localhost:59396/sss/sssHandler.ashx?
action=getproducts&ids=" + ids,

[code]....

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.

[
{
"ImageTag": "u003cdiv class="CarouselItem
"u003e<p><img src="http://www.xxx.com/image/

[code]....

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.

JQuery :: Testing For Error Condition In Returned JSON Formatted Data

Dec 14, 2010

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'.

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]..........

JQuery :: Malsup Form Plugin And The JSON Returned From A Form Submission: The Error Callback Is Always Called?

Aug 19, 2010

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:

pStatus=parsererror
pErrorText=Invalid JSON: {"nickname":"trytrez","success":"success"}

However, the JSON looks OK for me (and http:[url]...agrees that it is valid).

JQuery :: Load Html And Loop Through Json While Changing Html With Json Data?

Sep 11, 2010

I have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:

{"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
html looks like this:
<div class="Name"></div><div class="Age"></div>

So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.

var jsonData = {"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
$.each(json.Super, function() {
$('#box .Name').html(this.Name);
$('#box .Age).html(this.Age);
});

JQuery :: Use Data Returned In $.get()

Jul 19, 2011

Here is the code I am running:

The url is a very straightforward servlet that queries a database and returns either Y or N. That part is working fine. The first alert shows Y or N just as it is supposed to.

However, the second alert is always showing Turbo, as though the if statement is not able to compare properly. This is probably javascript rather than specific to jQuery, but can anyone see where I'm going wrong?

Rounding Returned Value From Jquery.css

Sep 7, 2011

So just found out the problem I was having, and came up with a solution (bandaid really) but would like to know if anyone else has run into this and what they did.

Code JavaScript:
var left_margin = $(this).css('margin-left').replace(/D/g,'');

So the above, get the left margin of the object, strip all but numbers and store into a variable. Easy, right? Here's what happened. Inserted the object into the DOM, Chrome returned 212px, which was converted to 212�*fine. Firefox on the other hand returned 212.5px, which was converted to 2125� not fine. I'm centering the element on the screen based on this number, so the additional 2000ish pixels is WAY off. My solution was to increase one of my initial values a single pixel in which both browsers return 213px�*but like I said this is only a bandaid solution. Not really understanding the value of .5 pixel, but looking into that. Is there a rounding function in jquery? Javascript I would have to strip the px from the string, convert to integer and THEN round.

JQuery :: Animate Ajax Returned Data ?

Jul 8, 2010

$.ajax({

So I'm loading the div#my_events by prepend(data) where "data" is another well styled div. Is there anyway to animate this returned data. Unfortunately I can't just specify a unique ID on the incoming data. So I was wondering how else I might be able to address this data I'm returning.

It is basically a topic list, with a modal that sends jquery to add a topic to the database, and returns the topic from the database, hides the modal, and displays the last added topic at the top of the topic list. Now I'd like it to do something slightly fancy like animate the color of the background to bring the user's attention to it.

JQuery :: Events On Elements Returned Using Ajax?

Oct 7, 2010

I define a "click" event on "a" tags in the ready part of a page. It fires just fine when I click on any "a" tag on the page. I then have a button which sets the content of a div using ajax. This content contains a couple of "a" tags. The issue now is that the "click" event does NOT fire when clicking on these tags. I suspect it is because they did not exist when the page was initially rendered. What is the "JQuery way" of dealing with an issue like this? Of course I cannot be the only one in the world who needs to return HTML with events from my ajax calls :-)

JQuery :: Extracting Data Being Returned From PHP Script?

Jul 5, 2009

Here is what I'm trying to do. I will pass a directory to a PHP script, that script will then return an array of filenames back to the javascript that called it. In the javascript I want to take the filenames returned and create links to them in an unordered list.

The PHP code to get the filenames is done and when I run the script I get an array that I have formatted into json... an example of the encoded array is as follows...

{"filename:["file01.jpg","file02.jpg","file03.jpg","file04.jpg","file05.jpg","file06.jpg"]};

So here is the jquery I'm trying to use to get the filenames and create my links... But I must be missing something because my variable... data ... is empty... but status is Success.

JQuery :: Ajax Returned Data Format ?

Sep 23, 2009

Getting information from a php file. Basically :

MY JAVASCRIPT FILE:

In this dumb example, I'm unable to match the 'data' returned variable with the value I assigned to it in php (I can't manage to enter my 'do stuff'), yet its value is 'ok' if I display it. I have no problem to retrieve html code from php and inject it in my pages, but I can't test it as a regular javascript string.

What's wrong in this ? What have I missed about the 'data' format ? Do I have to 'cast' data to a javascript string (and if so, how ?)

JQuery :: Last Line Of Returned Rows Not Colored

May 13, 2009

I have a function that is calling a list of events. Within the <code>.each</code> is alternating row colors code (see below):

function DisplayEventList(info,event_id){
$.post('/url/server.php',{
request:info,
event_id:event_id
},
function(xml){
$('#event-listing tbody').empty();
$(xml).find('list').each(function(){
var startdate = $("start",this).text(); .....

My problem is that the last line of my returned rows isn't coloring. If 14 rows return, the first 13 will alternate coloring, but the 14th will not. Consequently, if only 1 line is returned, it does not color.
