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 :: Malsup Form Plugin - If I Have Iframe: True, My JSON Response Back Is Always?

Oct 12, 2010

Currently using: version: 2.47 (04-SEP-2010)

If I have iframe: true, my JSON response back is always:

<head></head><body>{"WEBSITE_URL":"test","ASSETTYPE_ID":0.0,"ASSET_RESULT":{"ASSET_ID":9,"ERROR":false},"ASSETTYPE":"link","NAME":"test","DESCRIPTION":"test"}</body>

Was this done for a specific reason (note the Head/Body tags)? Is there a safe way of parsing this JSON request out? Am I doing something wrong?

JQuery :: Malsup's Form Plugin Uses .attr() For Disabled - IE7 Drops Form Fields W/ JQ Core 1.6.*?

Jul 11, 2011

We're using Malsup's form plugin v2.82 and jQuery core 1.6.2. We're having issues in IE7 where, on a form with file upload, form fields are being dropped before the form is submitted to the server.We tracked it down to the `fileUpload` function, specifically line 196 where each field in the form data has `.attr('disabled',false)` run against it. If we change this to`.prop('disabled',false)` it all works fine.I don't see a clearly marked place to submit bug reports for the form plugin, and wanted to verify that others see this as well,

JQuery :: Malsup's Form Plugin - Submit Only PART Of A Form?

Aug 24, 2010

Malsup's most excellent and comprehensive Form plugin has me completely stuck on just one thing.Take a look at this: http:[url]....At the bottom are a variety of submit buttons, and when you click one, it knows which one has been clicked.And I've been through the js and the source and the examples and I can't figure out how the bleep it's done!I'll tell you why I'm asking, then perhaps you can probably tell me I'm doing it wrong anyway!Let's say a blind person logs in, and want to edit their presets.I don't want the form to be too complex or clever or ajaxy, as screenreaders don't like that, so it just iterates through as many presets as they have, and populates a form with edit boxes.But there's no point "pushing back" 29 unchanged items just to edit one row.

So my idea was I'd just "fieldSerialize()" the details of the row that was currently being edited and submit that to my little php routine that updates the db. Then they can do a refresh just to hear the list again.The js looks like:

$(document).ready(function() {
$('#myForm').ajaxForm(function() {
var queryString = $('#myForm').formSerialize(); [code]....

All works fine like that. But if I change line 3 to: var queryString = $('#myForm :button').fieldSerialize(); it doesn't work. I've also tried:

'#myForm :button'
'#myForm .button'
':button'[code]....

Maybe I should just generate as many separate forms as there are presets, but then I'm going to need as many ready(function)'s as there are rows, which is going to be very messy.

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 :: Form Plugin By Malsup Success Function Not Working On IE7 - Works On IE8

Oct 7, 2010

I'm trying to submit a form with the jQuery Form Plugin by malsup. I'm fairly positive my code is correct because in IE8 the success function is being called and the background of the boxes are turning green. In IE7 however, The submit function is definitely working as the file is uploaded to the correct place, but the success function is not being called/fired. Any ideas as to why this might be? Do IE7 and IE8 handle this that differently? The function in the success call is just changing a checkbox and combo box background colors to green.

JQuery :: Form Plugin By Malsup - Max Is Not Explicitly Defined As A Var So It Becomes A Global Variable?

Oct 13, 2010

In the function 'formToArray' the variable 'max' is causing a conflict in my application. The reason being that max is not explicitly defined as a var so it becomes a global variable.So IMHO:

#520 - var i,j,n,v,el;
for(i=0, max=els.length; i < max; i++) {

should be changed to

#520 - var i,j,n,v,el, max;
for(i=0, max=els.length; i < max; i++) {

JQuery :: Getting Plugin Within A JSON Callback Function?

Oct 8, 2010

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.

JQuery :: Attaching Validation Plugin Callback To Modal Form Button

Jun 5, 2011

I am trying to use the jquery validation plugin with a modal form. When I click the 'Make a booking' button shown below there is no response. I guess there's something about the dom I am missing, which tends to be the case quite often.

$('body').click(function(event) {
if ($(event.target).is('a.add')) {
event.preventDefault();
$( '#dialog-add' )
.dialog( 'open' );
}});
$( "#dialog-add" ).dialog({
autoOpen: false,
height: 340,
width: 400, .....
draggable: false,
position: "center",
resizable: false,
modal: true,
buttons: {
"Make a booking": function() {
$('#addbooking').validate({
submitHandler: function(form) {

//ajax
});
$( this ).dialog( "close" );
}});},
Cancel: function() {
$( this ).dialog( "close" );
}},
close: function() {
}});

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 :: Prevent A Particular Field Being Submitted In Form Submission - Ajax Submission Doen't Work

I have email, password and some other fields, and I'm using $.post to send data for Ajax submission.

The problem is that I don't want to submit a particular field. The serializeArray() returns all the fields in the form. So, I tried something like this to prevent the password field being serialized.

This works great but the ajax submission doen't work.

JQuery :: GetJSON Fail On Callback - Callback Is Never Called ?

Apr 13, 2010

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.

JQuery :: Star-rating Plugin Callback Function Throwing Error?

Jan 9, 2009

I'm using this star-rating plugin [URL] and the call back function provided to allow for submission of forms onclick of rating star.

Code:
$(document).ready(function() {
$('form.entry_rating').rating( {
callback:function(value, link) {
alert(value);
}
});
});

However, once the callback is included I get an error I've been trying to track down for the past day and a half. In IE the error thrown is "Object doesn't support this property or method" on Line 100 character 4. In my JS debugger the plugin breaks on line 99

JQuery :: Form Validation Error Messages Not Showing / When Using File Input Plugin

Aug 8, 2011

I'm using the jQuery form validation plugin along with the fileinput plugin which hides the initial input area, but uses <divs> and some styling /javascript to show the file input field.The issue I am having, is that the 'this field is required' text that is meant to show on submission, doesn't come up for the file input field, nor some checkboxes that I have in a table. I am guessing that this is because the code is needing the label to be RIGHT next to the element (in this case the file input or the checkbox) in order for the validation message to show..Are there any work arounds that anyone knows of so that I can get the error message to show?Is there a way to show the error message for required fields when they have a div wrapping them or anything wrapping them?

JS Form- OnSubmit - Function To Be Called Continuously After The Form Is Submitted?

JQuery :: Form Submission To Two Actions

Oct 12, 2010

I've got a form that I need to go to two different places. First, I need it to submit a portion (but not all) of inputed data to one url (url.php). If that is successful, I need it to submit another portion of the inputed data to another url (url2.php). The trick is, I need the information from some fields to go to both places, but with different names.

Here's what I'm doing:
$(function() {
$('form').submit(function() {
return false;
$.ajax({
type: "POST",
url: 'url.php',
data: $('.string').serialize(),
success: function(){
$.ajax({
type: "POST",
url: 'url2.php',
data: 'firstname='+$('#Contact0FirstName').val()+'&'+'lastname='+$('#Contact0LastName').val()
});
}});
});
});

I have the information I need to go to url.php serialized by class (.string). Then, I try to make a string out of the data for url2.php. What seems to be happening the form is submitting ALL fields to url.php, ignoring the serialized string I told it to use, and then submitting ALL fields to url2.php, again ignoring the string I told it to use.
