$.get(queryString, function(data) {
attrIndexes = data.split(",");
});
after running this code the original variable is empty so something is wrong
I've attached a cut-down version of a script I am working on. It's a pretty simple button with a function attached, which creates a random number and compares it with a preset value.I can't seem to get the function to read the variables
Code:
#<html header>
<script language="javascript" type="text/javascript">

I've got a function displayResults(imageArray); that first calls removeElements(); to get rid of the currently displayed list items. Both functions are part of class function eventBox(array, string, date). both displayResults(imagearray); and removeElements(); have been bound to eventBox(); by e.g. this.removeElements = removeElements;
However, from within displayResults(imageArray); this.removeElements(this.identifier + "eventsul"); evaluates to "undefined". Also, this.identifier called from within the function also evaluates to undefined (it doesn't in other functions). For some reason I can't access global functions and variables from displayResults(imageArray);. Any ideas?
Here is the code for displayResults(imageArray); :

I'm making some changes to a google chrome extension I made and am having some trouble. Heres my code on a content script page (removeAttr.js) :
chrome.extension.sendRequest({greeting: "whitelist"}, function(response) {
var whitelist = response.whitelist;
console.log(response.whitelist);//working
});
alert(whitelist);//alerts "undefined"
How do I acess the whitelist variable from outside the sendrequest() function?
Iv tried saving it to a window.var variable with no luck. Iv tried creating a div and assigning it's innerHTML as the whitelist variable and getting it later with no luck. The fact that it's a chrome extension complicates things because i dont actually know if i can create elements from where the script is located.
i declared 2 variables which i want to use depending on a conditional statement inside a jquery function unfortunately they don't seem to be working. do they need to be globals?[code]i know for a fact that the code works, when i add an alert inside the conditional statement it pops up fine, but these variables don't seem to get their values applied.

Im trying to do the following thing, I have a function in javascript which I want to use to call anAJAX event, during this event the variable that is set in the function needs to be passed to the file called by the AJAX event. Basically I create 2 different versions of the same stuff inside the AJAX called files using the variables. But im running into some cross browser related issues, this all works fine in FireFox. However in Internet Explorer it sometimes works but gives javascript errors on line 99999ish. I have the following setup:

i have this problem in passing values to a variable in a jquery function.
i have a js variable that accepts a certain value and then i want to pass this variable in the jquery function.
For example, this is my script:
var autoScrollBool = "true"
var autoScroolInt = "10" (seconds)
stepcarousel.setup({
[Code].....
i want to replace the value of autostep: {enable:true to enable: utoScrollBool(the variable i created) , when i tried to assign it as is, its not working.
I am trying to use jQuery to populate a number of divs with html from external blog pages:

I understand that the 'i' variable is out of the scope of the inline function but I really don't know any other way of doing this.
I want to call a javascript function when a <span> is clicked, pass two variables to it, and then use jquery to hide that span.
A simple example is:
The variables (1,3) & (8,9) are loaded dynamically with a php script. Adding the two variables together isn't the intent of the script, but it seems the simplest way to explain what i'm after.
So how do you get $(this) to work in a function that has to have variables passed to it?
all on the same page that are accessed by the classic show/hide DIV functionality.
So user clicks button 2, which shows story 2, hide stories 1 and 3. (all on the same page).
The issue is that I've been asked to provide a method to directly link to story 2 or 3, which currently isn't possible since you need to load the page, then click the button to show story 2 or 3 (naturally 1 loads by default).
So I'm looking for any method to go right to story 2/3 from a link.
Perhaps I can pass a variable through the URL which executes the function as soon as the new page loads (which would mean a quick double page load but I could handle that)
Here's the function:
var showMe = function(me) {
document.getElementById(me)["style"]["display"] = "block";
}, hideMe = function(me) {
document.getElementById(me)["style"]["display"] = "none";

I'm not an ace JSer by any means--the problem I'm about to pose could easily be solved with pointers in C++ (the language with which I am most familiar), unfortunately that is not an option.I am making a webapp using the google visualization API:URL...My problem may be related to the API, but I think it's more Javascript oriented--the Google group for the API is helpful,I have a function, drawDash(), which declares some elements of the visualization, some filters for the visualization, then binds them together and draws them. Now what I need to do is access the elements of one of those vars, specifically a filter, and add/change properties of it with an HTML form.
I've set up an onclick function for a set of checkboxes in my form that calls another function. The problem I face is that I can't really access the filter correctly.[code]So basically, I want to have a function be able to edit the var serviceSearch from another function.
is there a way in jQuery to bind variables to function calls similar as prototype.js does it? See [URL]
E.g. in the slideUp method of jQuery you can specify a callback that is called after the effect has finished. I would like to bind a variable to this call so that it is used inside of this callback as a closure.
I have the following function:
function containsurl(index){
var theurl = "[URL]";
..
}
I need to use the theurl variable in another function, how can I do that?
<script type="text/javascript">
function popsizes(colorcode) {
var BLK=new Array();
BLK = ["2XL","3XL","4XL","5XL","LG","MD","SM","XL","XS"];
elem = document.getElementById("selcolor");
for (i=0; i<elem.options.length; i++){
sizelist = colorcode[i];
document.getElementById("selsize").options[i] = new Option(sizelist);
}}
</script>
In an event, i'm passing in "BLK" as the colorcode param. This is creating my selsize select box with B, L, K, and undefined options until the for loop finishes. ie, its taking the passed in colorcode as a literal string, instead of referencing the array. Anyone have a pointer as to how i can access the arry, instead of the literal string?
Is it possible to print out the variable from within a function? In this particular case, I am trying to show the 'soundfile' variable I set in the playRandomSoundNoWindow function.
