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.

Variable Scope Inside A Function

Oct 30, 2006

I think I've had JavaScript variable scope figured out, can you please
see if I've got it correctly?

* Variables can be local or global
* When a variable is declared outside any function, it is global
regardless of whether it's declared with or without "var"
* When it is declared inside a function, if declared with "var", it's
local, if not, it's global
* A local variable that is declared inside a function is local to the
whole function, regardless of where it is declared, e.g.:

function blah() {
for(var i ... ) {
var j ...
}}

i and j will both be visible within blah() after their declaration.
* the notion of "function" in this context also applies for this kind
of construct:

var myHandler =
{
onClickDo: function()
{

in the sense that whatever one declares inside onClickDo with "var"
will only be visible inside onClickDo. What else, am I missing anything?

Implementing A Variable's Value Inside A Function

Jan 9, 2008

I'm making a project which creates tabs with a class. I don't really know how to explain it better but this is how it works:

<a href="#" id="tbs_tabs">Create</a>
<script type="text/javascript">
var tbs = new Tabs('tbs_tabs');
tbs.theme = 'classic'
tbs.create_option('abc','#');
tbs.create_option('abz','#');
tbs.create_option('abf','#');
tbs.create();
</script>

It first creates the new class and tells it the id, then it creates as many options as you want and creates it.

My problem is with this line:
for(i=0;i<this.option_values.length;i++)
{
li = document.createElement("LI");
li.appendChild(document.createTextNode(this.option_values[i]));
addEvent(li,"click",function(){oThis.select_option(i); return false;};

ul.appendChild(li);
}

What I was trying to do here is add an event to the LI element that refers to the current tab class but doesn't use the CURRENT i value but the value that was when the event was first created.

For example.. If my i value is currently 2 and I add the function, then I want that when I call the function, the value will still be 2 and not the current i value. What happens now is when I call the function the value is something like 5 or 6.

Variable Inside A Dynamically Created Function?

Jan 20, 2010

I have a set or icons that which over time I replace with a different icon and and add a onclick event to them. This is my code

function updateStatusIcons(retText) {
updatingStatuses = true;
var updates = retText.split("|");
for (z=0; z<updates.length; z++) {

[Code]....

Everything works fine except for the onclick event. In the hover message of the icon, the correct project ID is displayed in the message, hoever in the function, the onclick funtion always loads the page with the last set project id. How can I pass the project id into the onclick function and make it stay fixed and not be the value of that it was last set to?

Placing A JS Function Variable Inside A Form?

Dec 29, 2010

This is a follow-up to a post from long ago. I had thought that this would be very simple but damned if I can get it to work.

Basically, I want a value which is generated in a JS function to be included in a <form method="get"> output. For some reason which is beyond me, the value is not being updated and the form is returning only 'undefined'. Here is the code:

JS:
<script type="text/javascript">
function addRow(tableID) {
// CELL 1
var table = document.getElementById(tableID);

[Code]....

For the record, the page is up here: [URL]

Jquery :: Php - Variable Not Changing Inside Click Function

Dec 22, 2010

I have a list of most 17 recent entries from a db table and wanna use jquery/ajax to have a next button that loads the next 17 entries when you click it. It passes the 17 variable to the .load which works fine first time around (this is later used as mysql limit), but then I try to increase the start variable with 17 so that next time I click it would pass 34 to the .load (so it loads next 17 again) but this doesn't work, it simply loads same 17 again on 2nd, 3rd ect. click (so nothing changes). use global variables by setting it with var and using it without var inside the function.

<script>
var start = 17;
var loadUrl = '<?php echo site_url('welcome/battles'); ?>';
$("#latestbattlesnext").click(function () {

[code].....

Access/change Variable Inside Lambda Function?

Aug 17, 2010

In one of my functions I got the following lambda function. It works as intended, but I got a tiny problem. I'm trying to access the function-scooped variable "matched" and set it's value to "true". The problem is that it seems like the variable is existing as a local variable inside the lambda function, even if it's not declared inside the lambda function itself. So, the change "matched = true;" does not effect the variable that I declared.

Code:

//... code
var matched = new Boolean(false);
xmlhttp.onreadystatechange=function() {
if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {

Multiple Array And Display - Declare A Variable Named Total With An Initial Value Of 0

Sep 17, 2010

I am looking for a push in the right direction for a few problems i am running into; my first problem is I have to create a script element that contains the function amountTotal which should return the sum of all the values in the amount array. There are no parameters for this function, and I have to add the following commands to it.

1. declare a variable named total with an initial value of 0

2. create a for loop thatloops through all of the values in the amount array, at each iteration of the loop, add the current value of the array item to the value of the total variable.

3. and after the for loop is completed, return the value of the total variable.

The amount array has already been created and populated in a list.js file, I had to first create a script element pointing to it.

This is what i had for my link to the list.js file and funtion :

I have my entire code written but i am trying to break it up and fix my problems 1 at a time: when i open the code, it does'nt display correctly ( which is another problem) but I ran the debugger and it says my total is undefined. ( this is in another section of my code), but I guess my function is wrong somewhere.

JQuery :: Cannot Get Variable Inside Loop Back To Original Function

Oct 22, 2009

I'm having some problem with return value for a function. I'm trying to access google blogger's API to display blog entries on my site. I'm doing this through JQuery and requesting a JSON response. Everything seems to work ok, but I want to access the link for the blog entry. This is a subset of the "entry" object.

It's structured like this:
Entry:
title,
content,
link:
rel,
type,
href,
rel,
type,
href,

I want to get the link where the "link.rel == "self". To do this I have to loop through the link object (5 times). The loop and conditional statement works correctly, but I can't get the variable inside this loop back to my original function.

I have this code:
$.each(data.feed.entry, function(i, entry){
$.each(entry.link, function(j, link){
if(link.rel == "self"){
var postlink = link.href;
alert("link : " + postlink);
return postlink;
}});
alert(postlink);
});

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"]} ); };

Variable Returns Correctly In FF - Incorrect In Chrome

Dec 22, 2011

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...

Accessing Width Variable - Returns Undefined

Feb 13, 2009

I am trying to access the width variable from my main page. Within the imageinfo.js script functions I can alert() the width value which returns 1024. But I can't seem to pass this variable to my main page or access it directly so that I can use document.write() to write the variable on the page. Whenever I try to call the 'width' variable directly from the main page I get undefined. How can I access this variable? However, with the test code below, I was able to get ducument.write() to write the 'width' variable on the page but now the page doesn't stop loading - there's an endless loop in the code...

Code:
BinaryAjax(url,function(http) {findEXIFinJPEG(http.binaryResponse);test(width)},null,useRange ? [0, Range] : null);

Main page
Code:
<html>
<head>
<script>
function test(width){
document.write('Image Width = ' + width)
} </script>

<script type="text/javascript" src="binaryajax.js"></script>
<script type="text/javascript" src="imageinfo.js"></script>
</head>
<body>
<script type="text/javascript">readFileData('image.jpg')</script>
</body>
</html>

Imageinfo script - This script uses the binaryajax script found below.

function hasLandedOn(){
var selectorLoc = $("#selector").offset();
var imageName = "";

Clicking In List Box White Space?

Jan 19, 2010

Right now when someone clicks on my listbox I immediately do an update on the form to populate the selected item.

Is there a way to detect if a user has clicked on some white area of a list box? If my list is sized 8 items but the list only has 4 items, if the user clicks near the bottom of the list where there is no item to select, can I detect that? Currently I get the form updating even if I click on the white area of the list and I'd like the form to update only if I actually click on an item in the list.
