Global Variable - Why Is It Undefined?

Aug 28, 2009

I code my global variables first, then my window.onload function, like this code...

Why do I get the error:

"KBINPUT IS NOT DEFINED"?

and

Why doesn't the IF statement for UNDEFINED element catch the problem?

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.

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.

Global Variable Not Valid In Callback Function?

Aug 4, 2010

I 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;
$(document).ready(function(){
resize();

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.

Ajax :: Variable Is Undefined Outside Of Callback Function?

Mar 4, 2009

I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.

Heres the situation:

I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need

**************code*****************************************
//new ajax already created and assigned to the variable xmlhttp//
var response_recieved = "some data";
function get_answer(Table_Name, Field_Name, Data_Type) {

[Code]....

As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.

Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???

get the variable response_recieved to survive outside of this function.

Resolved Undefined Variable In Function - Scope?

Oct 27, 2009

I'm just starting out with Javascript as a development language and this will probably be a relatively simple problem for someone to solve for me.

I am trying to access a variable (this.bodyEl.innerHTML) from within a function but get an error message indicating that it is "undefined". I know that it is a valid variable because I call it elsewhere outside of the inner function itself.

I'm sure this is just a scope issue, but I'd welcome any suggestions on how to solve it with an explanation of where I've gone wrong if you have the time.

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:
