Using A Variable From Url In Function

Jul 11, 2011

How I would modify the following function to get it to check if a url variable is present and if so to add it into the string variable for the url.


If my url is index.php?make=Apolo then I need to get this added into the var queryString part of the function so that the ajax returns the correct values.

Declare A Variable Inside A Function - Returns White Space - Not Variable Value

Aug 17, 2010

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:

function show_video1(){
var video1Name = "Education World News (Part 1)";

and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.

JQuery :: Use A Variable Declared In A Function Outside A Function?

Nov 17, 2011

So I've got this checkbox thing going on, where an array converted with the value of each checkbox in it.It looks like this:


What I want out of this function is the variable newworkdays to use in another function.

How do I access the "newworkdays" outside the function? I've already try to declare the variable outside of the function, though that resulted in that I didn't get the value of the variable inside the function.

Passing Variable To A Function Inside A Function?

Feb 10, 2010

Here is the code:

for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
var type = {


Now, basically what I am doing here is running through one array to create an array of objects, that will be used to create links that will use whatever onClick function I pass it. The problem is that on the second line I need the BS_crm['activityTypes'][i]['id'] to be a value, not a reference. If that line was simply changed to:

var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };

Accessing A Variable Defined In A Function, Outside The Function?

Sep 18, 2010

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;
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.

Use A Function With More Than One Variable?

Feb 18, 2009

I am currently working on a code that has a function within it called findHighestValueIndex which will find the highest value in an array. The problem I am having is writing this function so i can call it in the program to work on 2 different arrays. I already have it working on the array assesmentScoresArray, but I also need it to work on the weightedScoresArray. Is it actually possible to do this or do i need to write another function that is almost the same but with the arguments etc for the other array? I will paste the code below so you can see where I am up to. I am a novice in programming so im probably going about this all the wrong way

Pass A Php Variable - Through To A Function

Mar 4, 2009

If it is possible to pass a php variable through to a javascript function.


I have a bit more to the code but that is the bare essentials as an example. If i remove the $id and $name from the passTest() for onClick the function works properly. However if I leave them in the function doesn't seem to work at all.

Passing Js Function Variable For Id

Aug 14, 2009

I am having trouble passing the correct id to change the innerHTML. I have a jsp that display people and their address information. There could be several people in the list, so it is in a loop. That part all works good. There is a drop down list with countries in them. Based on the country they select, I want to change some of the text. Here is what I have:

<td class="datashaded" valign="top"><font size="2"><b>Country:</b></font></td>
<td class="datashaded" valign="top">


When I hardcoded the id= value, not matter which group I changed the country on, only the first one was changing, so I knew I needed unique ids for each group. There is more to the table, but this is the good part. When the onChange fires now, Nothing at all happens.

New Function Variable Passing?

Apr 22, 2011

I have a function which is currently called twice on the same page. Part of the function is to apply an onkeyup event to a created element. The problem is that when the function is called twice the first created element calls the onkeyup function of the second element!

table_JD.length-1 = 0 for first element
table_JD.length-1 = 1 for second element
updateSearch_TC_JD(1) is somehow called from first element!
newSearchBox.onkeyup = function() {updateSearch_TC_JD(table_JD.length-1)}

Right now the variable name data.cells[i].letter is being based through the buildString function for each cell in my board, instead of the value of the variable. Same goes for the x and y variables.

Calling A Function Containing A Variable?

Jul 12, 2010

I am trying to call a function from a link or button like the example below, however I would like to call the function whilst passing a variable along (not a string).

This isn't my code, it is a simple way of explaining what I am trying to do.

<script type="text/javascript">
function myfunction(txt){


So instead of 'java too!' I would have a variable named "category" which could contain different data each time the button is pressed.
