Global Variable In A Function

Jul 20, 2005

I 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.

[Code]....

The purpose behind this is creating a form that will work with an existing database that would normally have a text area with lots of information. I am trying to turn it into a checklist that I can run from a mobile device. The global variables woudl be used to fill in a hidden text area that would then be passed on to the database upon submission. I am trying to keep the code as compact as possible.

Global Variable Not Valid In Callback Function?

JQuery :: Create A Global Function And Store The Return Value In A Variable?

May 15, 2011

I tried creating a global function to calculate the distance between 2 points.

jQuery.distance(p1, p2){
var dx = p2.x - p1.x;
var dy = p2.y - p1.y;
return Math.sqrt(dx^2 + dy^2);
};

Somewhere else within my code, I declare a new variable in order to store the value returned by the distance function.

var distance = $.distance(particle1, particle2);

However this is not working.

Eliminating A Global Variable

Jul 23, 2005

I've created a site where the pages generally contain a table of
contents (site map) down the left side. When each page loads, the
first function is called. The second function populates a global var
(array) of all the links.

I try to avoid using global variables, but I am stumped how to
eliminate this one (TocLinks) because other functions need to iterate
through it. I think the answer is to create a custom object that the
other functions can access. But I need some pointers on how to
proceed.

Here's the function that the pages call initially and the 2nd function
that it calls:

Passing Value To Global Variable?

Mar 15, 2009

I have a site that calls the function welcome() and displays a prompt. The same site also has an iframe that calls the next function, add_name(), but when the pages are loaded it says that "answer" is undefined.It says on the page, where the <p id="guest"></p> is, "Welcome undefined". How do I make it so that the value of answer, which is given onLoad of the 1st page with the prompt, is displayed as text in function add_name()?

[CODE]
function welcome(){
var x = document.getElementById("body");

Undefined Variable (global?)

Sep 21, 2006

I'm currently coding the beginnings of a stopwatch script.

<html>
<head>
<script type="text/javascript">
var startTime;
var currentTime;
var started = 0;

function startStopwatch() {
if (started == 0) {
var startTime = new Date();
display();
alert(startTime);
}
}

function display() {
currentTime = new Date();
difference = (Number(currentTime) - Number(startTime));
document.stopwatch.display.value = difference;
setTimeout('display()',10)
}

</script>
</head>
<body>
<form name="stopwatch">
<input type="text" name="display" readonly="readonly" size="40">
<input type="button" name="start" value="Start" onclick="startStopwatch();">
<input type="button" name="stop" value="Stop">
<input type="button" name="reset" value="Reset">
</form>
</body>
</html>

The value of startTime when called from display() is undefined. I'm not sure why, as I declared the variable outside the function. The variable should be accessible by all functions, right?

Any help would be appreciated.

How To Build A Reference To A Global Variable

Jul 23, 2005

I declare multiple variables halfway down the page. The number between "mech" and "Num" is generated dynamically in the XSL. Later on I need to reference that variable in a function, but I need to build the variable name in script. How do I convert it from a string reference to a ref to the global variable?

function changePreference(pos,mt){
//mt does not reference mech2Num, I need it to.
}
changePreference(2,'my' + pos + 'Num');

var mech1Num=1|2|3|4|5|6;
var mech2Num=1|2|3|4|5|6;
var mech3Num=1|2|3|4|5|6;

Can I Assign An Event To A Global Variable?

Oct 4, 2007

I was wondering if anyone knew if/how to assign an event to
a global variable?

I tried to do it and IE 7 came back with an error saying "Member not
found"
My code looked similar to the following:

var globalEvevnt;
function showPopup(event){
globalEvent = event;
alert(globalEvent.type);
setTimeout(function(){unhideDiv()}, 2000 );

}

function unhideDiv(){
alert(globalEvent.type); //Member not found error found on this
line
}

I was wondering if I had declared the globalEvent = new Object();
would that make any difference? I thought everything in JS was an
object so the event could be stored to one as well?
