Cannot Access Global Variable Inside Object Declaration
May 9, 2011Well, it turns out IE8 has yet another problem. My code has a global variable (to the object) inside an object declaration that cannot be accessed by a function (that is also global).
The code is like so:
Code:
function myobject(params){
//public
this.initialize = function(){...}
//private
some variables...
//problem variable
var mouse = new Object()
mouse.x = 0;
mouse.y = 0;
//code...
slidecontainer = document.createElement("div");
slidecontainer.onmousemove = function(event) {
if(boo.isIE) {
e = window.event;
mouse.x = e.x + document.body.scrollLeft;
mouse.y = e.y + document.body.scrollTop;
} else {
e = event;
mouse.x = e.clientX + document.body.scrollLeft;
mouse.y = e.clientY + document.body.scrollTop;}}
//this function is in an interval
function moveslides() {
/* this is where I have the problem
It seems that the function doesn't recognize that mouse.x, or mouse for that matter, exists. Mouse is global to the object, so why can't this function access it?
*/if(mouse.x) {
code...
}}}

Global Variable Inside A Document.getelementbyid.innerhtml?
Feb 5, 2010I have a little JS app that is a glorified calculator which I posted the code for below. My code uses the document object to replace the html in the "content" <div> and works great.However, I want to add an inline style in order to change the background of the input (readonly field with an id of "coutput") based on either of the global variables named "MJPD" or "IJPD", (depending on the switch case selected in the user prompt at the beginning of the script.)Simplified....if the value of MJPD is less than 4.6, I want the "coutput" field's background to be red, else be green.The same goes for IJPD, except the threshold for red will be <3.83.Code and what I have tried is below.
<script language="JavaScript">
var MJPD = 1;
var IJPD = 1;

Global Variable In A Function
Jul 20, 2005I have a .js file that receives a value from an html page. I'd like this
value to be a global variable that all functions in the .js file can use. I
have tried just declaring a var at the top of my .js file, but when the
value comes into the function and gets assigned to that variable, it is not
global.

Global Variable Not Valid In Callback Function?
Aug 4, 2010I am using jQuery 1.4.2 and I am trying to carry over the global variable totaltabs into my JSON callback function. The code seems to work properly, however, in my loadJSON function after the callback function loads the data, my totaltabs variable will not increment.
Here is a peak at my code.
totalItems is loaded from another function, not relevant to my example.
Code JavaScript:
var totaltabs = 0;

May 15, 2011I tried creating a global function to calculate the distance between 2 points.

Declare A Variable Inside A Function - Returns White Space - Not Variable Value
Aug 17, 2010I 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.

Passing Variable To A Function Inside A Function?
Feb 10, 2010Here 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 Scope Inside A Function
Oct 30, 2006I 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, 2008I'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, 2010I 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, 2010This 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);

Setting Parent Class Variable From Inside Function?
