Access/change Variable Inside Lambda Function?
Aug 17, 2010In 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) {

JQuery :: Can't Use Variable To Access Json Node
Jan 21, 2010why I cannot access json data by using a variable as a node name. I'm trying to grab a random quote from a .json file and display it in a div. When I access a node in the object by node name I can access the node data. However, when I try to use a variable in place of the node name (because I want to grab a random node) I get an object undefined error.
JSON object:
{
"quote1" : {"quote" : "hello, world."},
"quote2" : {"quote" : "goodbye, world."},
"quote3" : {"quote" : "out of this world."}

Not Able To Access Global Variable / Enable This?
Apr 3, 2010I'm trying to populate a web page with javascript. I have 2 functions. One that runs on-load so I can populate a dropdown list. The second one to process the selection when the user selects an item from the list.
I have a global variable in the top of my javascript that I use in the functions and as long as I set it in it's global scope, everything works fine. But what I really want to do is to pass this into the javascript running on this page via the code...
My question is. Where do I put this code so that I can use it to set the global variable "weekNumber"?
I've tried putting this code in the populateList function - NOPE! I've tried referencing it via window.weekNumber and this.weekNumber - NOPE. I'm stumped.
I've spent far too many hours trying to understand this without success. Can anyone help me figure out where to put this code so I can set the global variable weekNumber?
Is there a better way to do this?

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...
}}}
The page is at [URL] and works on every browser, including finnicky opera, except for ie. The full code is availabe when you right click and view the source on the page.
JQuery :: Access An HTML Fragment That Was Inserted By A Different Function?
Oct 19, 2010<html>
<head>
<script type='text/javascript' src='jquery-1.4.2.js'></script>
<script type='text/javascript'>
$(document).ready(function(){
[Code]...
The above is a simplified example of the problem I'm facing. I could merge functions into one big self-referencing function (i.e. recursive function), but that's ugly and causes other problems (such as when insert form elements and wanting to harvest the user input afterwards). I considered declaring a variable in the top ".ready" function, and have all child functions stuff their HTML changes in it, but that seems to be a pain to keep track of and removes much of the value of using jQuery in the first place...
Is there a nice solution for this? To, after inserting HTML, somehow update the HTML state referred to by jQuery in the non-local scope(s)?

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.

Access A Sub Function From An Onclick Event?
Oct 11, 2011I am working a project for school in which I am trying to make a simple math game. When the user clicks the start button it will bring display a question and ask for an answer. What I want to to is when the user clicks the start button it will swap the button for to other buttons to move to the next question and one to restart the game. Which works fine, the problem is after the buttons are swapped.
How would I access a sub function from a buttons onclick event? I currently have onclick="return MathGame.resetForm();" but that throws an exception and I can't see where. What is the best way to go about this. Also this is my first attempt at using javascript in this manner so I'm probably going about it the wrong way.[code]...
