JQuery :: Accessing An Objects Array From An $.ajax Call?
Jan 12, 2010
I have an object with a member function that changes something on the objects state. This works perfectly fine in the easy case. But when I use an $.ajax call within the function it doesn't work. Here is the example code and failing QUnit tests: [URL]
I have a page that creates one unordered list from the contents of another list. The second list is created from a database query and is hidden on the page. I have written a JQuery function shown below that does an AJAX call which causes the hidden list to be created and that is working perfectly. The problem is that when the code following the AJAX call is executed it doesn't see the hidden list. The alert message displays 0 the first time. clicking on the Load button a second time results in the first list being displayed. If I click on the Load button a third time, the previously loaded list is displayed; click on a fourth time and the new list is displayed.
In other words, it takes two cycles to display the correct list. I am at a loss as to what might be the problem. Other than this issue the code does what I need it to do.
I'm have some javascript objects with arrays that should be transferred as php array.Its posted by ajax httpRequest.How can I return php array, from the javascript?
I am new to jquery. I am trying to return a string array with two strings back to a jquery ajax call. On success, when I try to retrieve the values, my result is just a string "System.string[]". How do I retrieve the values that I returned from the server in my call back function for success.
I have a very large form and have a couple of checkbox groups where multiple items can be selected. They are grouped as an array of checkboxes. When I post the checkbox groups, the PHP script receives duplicate values. If the group has 2 checkboxes, 4 values are posted. If it has 10 checkboxes, 20 values will be posted.
i.e:
I then submit everything to a PHP script via an Ajax call, then output the result to a div. (see below)
However, when my PHP script loops over the $_POST array, it seems that each checkbox array is duplicated, so my PHP array returns:
This happens with all my checkbox arrays, but not with an array of hidden fields for some reason.
I don't think this is a PHP problem, as it looped over everything correctly when submitting via a conventional POST. I checked the contents of $_POST, and it seems that the duplicates are being posted.
I've got an array of names, and one ID. I need to run an ajax call using the ID and each lastname, until I get a successful hit on the ajax call. I can't quite figure out how to determine if the function that runs the ajax call has succeeded or not, it always returns false for me... Here's the code for the loop:
Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.
Can anyone tell me the best way to access a hidden object in a form? I could use a hard-coded index to the elements of the form, but it's too easy to add something before the hidden object and mess up the indexing. For example:
The form has a tagid of "myForm" The hidden object has a tagId of "myHiddenObj"
I can get the form elements by using var formElements = document.getElementById('myForm').elements
But there doesn't seem to be any way to do this: document.getElementById('myHiddenObj')
Assuming I have the elements as obtained above, none of these have worked for me either:
I am really hoping someone is willing to take the time to read this post and take a minute to take a look at my code. What is happening is there are some matches for a script I made and then an area for segments during an event. If you notice on the segment part of the form is that there is a dropdown that asks for where in the event that segment needs to go. With the Introduction or the different numbered matches. What I need to happen for a subArray I need it to take the introduction, all the matches, and all the segments and order them accordingly. With the introduction first, the matches in order based off there match number and then the segments in between the introduction or matches based off the user's input.[URL]..
I am writing this code <script type="text/javascript"> $(document).ready(function() { var obj = jQuery.parseJSON('{"a":"sss","b":"sss","question":"whi?"}'); //alert(obj.question); }); </script> How could I know how many objects variable obj has?
I'm a little puzzled over the possibility of accessing an array. I've declared the previd id - in the proxy.invoke call which works just fine (we have already implemented an .each loop which also works. My problem is this - after accessing the proxy.invoke function, the previd is populated correctly with push but after the call, we cannot seem to access the previd array to make a join to a string. Here's the basics of the code.
var previd = []; proxy.invoke("validdateIDCard", p_caregiverid, function(validaterID) { var valcard = validateID; previd.push(valcard); }, onPageError); var finalvalue = previd.join("|"); <-- this is where the problem lies - cannot seem to read the variable...
I have a set of functions that will transition/fade photos in and out as background images. Easy. But now I would like to run the same functions on a different html page with different photos (each different page represents a different JavaScript array).
I've been reading online on how jQuery methods can be called into functions. So my thought process is to create 2 methods (1 for the original images and the 2nd method for the other images).
So here is my base code which works... $.landingpage = function() {
/*Enable background image cycles on landing page*/ var images=new Array('/image01.jpg','/image02.jpg'); var nextimage=0;
im pretty new to jQuery, but familiar with JS in general. im trying to get a dom element by id to change the read only attribute. using jQuery i'm doing the following: var field = $('#name[index][index]').
but when alerting the field value, i get [object Object] and not an inputObject as i would expect.
i can use the normal getElementById and it works as I would expect. Is this a problem with jQuery?
I have kind of a complicated setup, and I was hoping to bounce this off some one's head who's more experienced with JavaScript.Assuming I have the following HTML markup:
i am having two global variables and i m setting their values on calling some function. After setting the values, i call a function in an object ...
if MyHint is an object and i am calling the function in it, but i am getting the values of global variables as undefined in the function of object MyHint. Is there any way to access the value of the global variables.
I am currently working on building a library and having my functions(methods) within my library. I am having trouble find some code for JavaScript that can help me to do the following:
I need to give an array of objects and the name of a key, return the array sorted by the value of that key in each of the objects: "a" + [{a:2},{a:3},{a:1}] → [{a:1},{a:2},{a:3}]
what i'm trying to do is to acces the content loaded via AJAX but in an other way than by a callback function.i have a div where the data will be loaded via ajax, the data is represented by a list of folders and when i click one of them i want to load then the subfolders and so on, but if i use the callback function this is not gonna be dynamic..cause i don;t know how deep is gonna be the tree.[code]but if i do in this way....first time it works....so id i click <ahref="folder_1">folder_1</a> it loads the subfolders...and if i click then on of the subfolders loaded with ajax it wont work anymore to see the subfolders in the respective folder.
So, I'm using code like the following and getting errors: result = a list of cars with each property separated by ',' and each car separated by '|' This code creates and populates the array (seems to work)
var carList = new Array(); var cars = new Array(); var properties = new Array(); cars = result.split("|"); for(var i=0; i<cars.length;i++){
As they all have the same property set but with different values I thought I'd try creating a servo object, the create an array of servo's but I don't think I'm getting anywhere fast. Heres what I have

Once this is done and I've got all the servo objects created with their properties, I'm hoping to be able to search for all servo's with a set property i.e all servo's with servo.application = 1 would that be possible, if not I geuss I'd be wasting all our time trying to create classes I can't use the way I'd like.
I have a list of about 70 servo's that I'd like to apply set properties too.As they all have the same property set but with different values I thought I'd try creating a servo object, the create an array of servo's but I don't think I'm getting anywhere fast.[code]...
