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:

[Code]...

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.

What Determines If A Variable Needs To Be Declared

Apr 26, 2009

I'm confused about declaring variables. I see variable explicitly declared with the keyword var, both inside and outside of functions, and I suppose that depending on where it is declared relates to variable scope. BUT, I also see variable used that have not been explicitly declared with var. What determines if a variable needs to be declared?

Validating A Variable Is Declared

Dec 7, 2006

I have a situation in javascript where (this is inherited code, so I gotta deal with it) a variable is being used without being declared, as

someVar = someExpression ;

The original developer was relying on IE which automagically creates javascript variables for the IDs of all HTML elements, so somewhere in the HTML, there's
<someTAG id='someVar' >blah </someTAG>.

Unfortunately, in Mozilla (Firefox), I get a javascript error indicating that 'someVar' is not defined.

I wanted to check to see if the variable was undefined, then define it
if (undefined == someVar) someVar = document.getElementById("someVar") ;

this gives the same error in Mozilla (undeclared variable). I saw a thread with this exact problem, but it looks like its been archived. Does anyone have the solution to checking in javascript if a name is "undeclared" as opposed to "undefined"???

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 = {

[Code]....

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;
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.

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(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...

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 :: Function To Run Depending On Variable Value

May 27, 2011

$("#ltr").live("mouseover", function() {
//swap class names
$("div#container").removeClass("rtl").addClass("ltr");
});
I run this function to swap class names when there is a mouseover event on an image with the ID "ltr". How would I run this same function but to occur when, for example, a variable "distance" was equal to 0? Basically, if distance = 0 then swap class names

JQuery :: Output Variable In Each(function())

Nov 3, 2010

I'm working on a project in which I parse the XML and I get the element names.

So far everything is ok.

Also, I would get a variable increment that I create in the function and I want to find out of it.

Unfortunately, I can not recover.

Here is an example of my script:

// start
// "i" is my increment variable
var i = 0;
$(this).find('foo').each(function(i){ // run correctly x time
i = i++;

[Code]....

How do I find my variable "i" to the output of my loop?

JQuery :: Pass A Variable As An Integer To A Function?

May 16, 2010

Let's say I have this function: function add(x, y) { var add = x + y;

[Code]...

So let's say the value of select_first is "1", and value of select_second is also "1". But when they are passed to the add function, the returned value is 11 and not 2. So what I understood is that it took the values as strings instead of integers. What should I do so that select_first and select_second are integers instead of string?

JQuery :: Pass A Dynamic Variable To Function?

May 15, 2009

I have a bit of php that creates an entry on a page for each row in a table, some pages may have multiple entries, others just one.

eg.

<h2 class="title">{title}</h2>
{summary}
<p onclick="openBox({entry_id})">Click to read more ></p>
<div id="{entry_id}" style="display:hidden;">{body}</div>

I would like to have just one function to open and close all individually, eg.

$(document).ready(function(){
function openBox(id){
if ($("#id:first").is(":hidden")) {

[Code].....

Well I know I'm doing something wrong as this is not working, and I don't know how better to explain I hope this is sufficient, I'm not worrried about the php/html bit as that is working fine.

Jquery :: Getting Effect Into Onmouseover As A Variable Or Function?

May 12, 2011

I've set up a jsfiddle here [URL]I've been working to reduce my problem to the basics, the end application is a bit more complex and I'm pulling data into the array dynamically using a query from our BI tool.

I'm trying to get the hidden div's to show/animate using the mousedown on the outer DIV. The second example (Belknap2) works (just click the div) because I've typed the code into the mouseover (which is the same text which the variable x results in).

When I try to make this a bit more dynamic, e.g., by calling the variable rather than typing the expression into the mouseover in the first example, it doesn't run.
