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.

Assigning Value To Global Variable In A Function?

Oct 5, 2011

how to assign a value to a global variable within a function and can't seem to figure it out. Here's my thought,

<script type="text/javascript">
var global1=""; var global2="";
function assign(vari,strng){

[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.

$(document).ready(function(){

Accessing Global Variables - Function DisplayResults - ImageArray

May 5, 2009

I've got a function displayResults(imageArray); that first calls removeElements(); to get rid of the currently displayed list items. Both functions are part of class function eventBox(array, string, date). both displayResults(imagearray); and removeElements(); have been bound to eventBox(); by e.g. this.removeElements = removeElements;

However, from within displayResults(imageArray); this.removeElements(this.identifier + "eventsul"); evaluates to "undefined". Also, this.identifier called from within the function also evaluates to undefined (it doesn't in other functions). For some reason I can't access global functions and variables from displayResults(imageArray);. Any ideas?

Here is the code for displayResults(imageArray); :

Function Defined In Global Scope Not Being Called By SetTimeout

Feb 2, 2011

I wanted to write my own script for a fade-in animation, since the ones I have found have got too many options or need some framework, which makes them unnecessarily big. I wanted to learn too.Unfortunately, the code didn't work as I wanted, and I commented some things so as to find out what's happening.Why is an object reference assigned to what was previously a string?

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.

Global Replace - Make A Function To Strip A String Of All Slashes

Nov 7, 2009

I'm trying to make a function to strip a string of all slashes. Initially I had:

Code:
String.prototype.stripSlashes = function ()
{
return this.replace('\','');
}

and that worked fine except it only replaced the first slash (which it apparently is supposed to do). So i read up about global replacements but cant seem to get the right combination of /s and s.
This is what i have at the moment:
