Variable Not Defined - Or Var Not Added Correctly?
Jul 4, 2011
I've been writing a new layout for part of my web page.
The java script is not creating the list. When I check Firebug I get an error:
QuoteMovies[movctr] is undefined [Break On This Error] MovieList+= Movies[movctr][2]
If I take out the var MovieList and just have it print the text "MovieList" instead of the contents of MovieList the code tries to run. I'm not sure why it won't copy the content of the var MovieList.
Live test version of my movie page
Here is my code:
It's also weird that is says that Movie[] is undefined instead of Movie[][].

i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?

I am currently working with a cms system that doesnt keep within the correct name conventions (pre defined).Within a form, I simply want to set a date to todays date:
<script type="text/javascript">
function initdt(mf) {
var t = new Date;
[code]...
This works perfect on a form I create, but sadly I must use a form within a pre defined system that uses "01-date" Is there a way around this? A simple way of setting 01-date to t.getDate();

My site is run on wordpress, but I'd like to customise the menu so that if the user is logged in the menu displays "Logged In" and if they are not it displays "Log In".Normally I would just use an if statement in PHP to output the required html, but as I can't use PHP code in the menu item I need to use Javascript. :mad:So, the way I figured this would work is:1) PHP code in the header checks to see whether the user is logged in2) This code then outputs JS to define a variable (varCheckLogin)3) JS within the menu checks varCheckLogin and outputs the html i wantThis sounds good hopefully. :DUnfortunately this isn't working at the moment. The code I have is:HEADER: (I know this works as the variable is being output correctly in the source code)
<?php if (is_user_logged_in()) {
echo '<script type="text/javascript"> varLoginCheck = "Yes"; </script>';
} else {
[code]....

I've a picture gallery with the images stored as variables in a javascript file like this:
var a100image10 = new mypicture("album1/a100image10.jpg");
var a100image11 = new mypicture("album1/a100image11.jpg");
I've a "next" button to show those images (one by one) in a div with this code:
document.getElementById('image').innerHTML = "<img src=images/gallery/"+eval(album+"image"+next+".getPath()")+"></img>";
where the eval function returns the path of the pictures.This works fine! but in IE I get an error saying a100image12 not defined (and image13, image14, etc), because that image is not in the javascript file.So, how can I test in advance if a variable exists in the file?? Note that I take the name of the next picture based on the current one.I mean,I take the current picture from the div, lets say a100image10, I add one, and I try to look in the file for the variable a100image11.

I have a global variable that I change depending on what's going on in screen.
And that function changes that variable.
For some reason, in FF, it modifies the variable as expected. But in Chrome, it doesn't.
Why is this? Is there any way to have consistent behaviour in both browsers?
In fact:
Returns true in FF, but false in Chrome...

I'm working on a script that will take the selected div and add an input to it.
If the div id="3" then when I alert it it works right but if the div id="post_3" then I get an alert of "object HTMLdivElement"
The javascript is simple(so far)
function create_reply_input(post_id){
alert(post_id);
}
And here's the php i'm using to populate the page with the posts
<li><a href='javascript:create_reply_input(post_$div_id);'>Reply</a></li>

Using a while loop in a function, I am trying to test an input character against a stored string of characters. I want the function to return the input character only if it is not in the stored string of characters. The code I've prepared is as follows:
<SCRIPT language = "JavaScript">
var storedLetters = 'sideways';
function requestLetters(aString)
{
var validLetter ='';
[Code]...
The code works fine if I remove it from the function wrapper but if the function is called I keep getting an error message that the variable validLetter is not defined. :confused: Can anyone see why this is the case?

Two objects on an html page. An event on object 1 effects object 2
$(".video_rg").mouseover(function(event){
var myTriggerId = event.target.id;
var myTargetId = 'video_' + myTriggerId;
document.getElementById(myTargetId).src = 'images/test_object_2.gif'; // this works
// $('#myTargetId').src = 'images/test_object_2.gif'; // this does not
});
My assumption (we know about those) is that I am not passing the data to the $() function correctly, that it is reading '#myTargetId' as a string, and not a variable. I just really want the JQuery code that would do what the document.getElementById code is doing.

I'm trying to select a class (.home) and an ID (#something) at the same time,
normally I'd use:
$(".home,#something")
but in this instance, the ID is already stored in a variable called "newpage" - I'm trying the following:
$(newpage,".home")
(note, selecting the id on it's own with just$(newpage) does work, so I know the issue isn't with my variable, it's just a matter getting both the class and the variable stored ID selected at the same time)

I've got this:
Code:
var noteCount = "";
jsonRequest('media.getFiles', params,
function(result) { noteCount = result['totalCount']},
function(exception) { noteCount = "0"},
true
);
The console returns results['totalCount'] with a value of 2 (that's correct).
When I call noteCount for display, it shows nothing. Neither the var set by result or exception.

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++) {

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 know it's something stupid I'm doing but I can't figure it out. Essentially I'm trying to load two objects with URLs with two websites that can be loaded(displayed) and unloaded(hidden) at the click of a button.
I've spent an hour trying to debug this and I'm at my whits end! I'm doing this with changing the width and height of the divs that contain the objects that will load the websites. But, in Firefox I get an error in the error console saying : loadUnload is not defined. why? code...

I am trying to test the id of three input boxes so that I can capitalize the first letter.
The fname and lname work fine but mi does nothing and I get no error is this because of the if statement or the fact that the mi only has one character?

This is an admittedly convoluted script, so I'm not surprised it's a bit buggy.Basically, I'm arranging several hundred small divs on a page. This code writes each of them onload, and checks urlArray to see if the specific div being written has a function attached to it, then enables onmouseover/onmouseout hand pointer/default pointers to it, and, of course, runs the function onclick.
var urlArray = ["main", "none", "none", "none", ... (snip) ]
var i = 0;
function writeDivs(){[code]....
The script as it appears here runs great in chrome, but Firefox tells me that "main" is undefined whenever I click or roll over the div, and IE says "object expected" when I click."main" is the name of a function defined in an external js file (though pasting the function into the main document doesn't do anything).In fact, the whole of the above script may not even be relevant, since the following doesn't work either:
document.write("<div class='posDiv' id='div"+i+"' onclick='javascript:main()' >"+textArray[i]+"</div>");

I think I have a simple problem, but unfortunately my JS skills are such that even something like this goes over my head. :/I have a site: buypermasetinks.c0m <-- I guess I'm not allowed to post real links yetOn the product pages, it uses JS to calculate the pricing of the different inks, based on their sizes. For some reason the JS no longer is working.I checked the error console and this is what I've found:Error: cloneObject is not definedSource File: buypermasetinks.c0m/permaset-aqua-standard-color-range-water-based-inks-pr-21143.h t m l Line: 667Here is the code found there:

I've tried to add a Lightbox script to an already existing page that already had a javascript feature in it. Now I know that there's no limit to the number of scripts you can run simultaneously, but when I added the lightbox feauture, my compiler gave me the following error:
$ is not defined
his.elements = $(this.options.thumb...lements(this.options.itemsSelector);
This line of code was part of the original source code of the page, and hadn't been a problem before I added the Lightbox code. Why is $ undefined all of a sudden and where can I find a solution for this? Could someone point me in the right direction here? I'm not exactly a novice(yet) when it comes to Javascript and this project was due yesterday.
