arr= []; will be arr=[112,184,234,543];

js1.js

Code:

 
var ABC_x = "112";
var ABC_y = "184";

js2.js

Code:

  
var ABC_a = "234";
var ABC_b = "543";

arr= [];
will be
arr=[112,184,234,543];
I tried this:

Code:

  
<script type="text/javascript" src="js1.js" ></script>

<script type="text/javascript" src="js2.js" ></script>

<script type="text/javascript">

window.onload=function () {

var arr = [];

var el = document.getElementsByTagName('script');

for(var i=0; i< el.length; i++)
{ 
if(el[i].innerHTML.indexOf('ABC_') != -1)
{
arr.push(el[i].innerHTML.indexOf('ABC_')[i]) ;
}
}
alert(arr);

}
</script>

It did not that. How can I do? Thanks...

<script type="text/javascript">
window.onload=function () {
	
	var el = document.getElementsByTagName('script');
	
	for(var i=0; i< el.length; i++)
	{ 
		alert(el[i].innerHTML)
	
	}
	
	arr = [ABC_x, ABC_y, ABC_a, ABC_b];
	alert(arr)
	
}

Using the DOM and/or innerHTML for this is silly. There's at least one better way.

So you can't modify those two external scripts?

Is the order of the numbers in the array important?

**Pepejeria** · Mar 18, 2007 06:54

He. There is no need to do innerHTML on that, the variables in the external JavaScript files are accessible once then load.

Code:

window.onload = function() {
    var arr = [ABC_x , ABC_y, ABC_a, ABC_b];
}

Which 7stud points out I just noticed...

Thanks...
Now I want to get the texts in the external JavaScript files. Message box will display the texts in the external JavaScript files. But it is not possible.

Code:

window.onload = function() {
    alert( display the texts in the external JavaScript files(js1.js)) ; // var ABC_x = "112"; var ABC_y = "184";
}

You mean that you actually want to alert the content of the external JavaScript file? I don't know why you would like to do this, but I guess you could do it using Ajax and retrieving a text file with that JS code.

Code:

<html>
<head>
<script type="text/javascript">

// If you define them like this it won't work, I dont know why, I thought it would
//var ABC_x = "112";
//var ABC_y = "184";
//var ABC_a = "234";
//var ABC_b = "543";

// if you defined them this way it will work
window["ABC_x"] = "112";
window["ABC_y"] = "184";
window["ABC_a"] = "234";
window["ABC_b"] = "543";

var arr = [];

window.onload = function () {
	for (var thingy in window) {
		if (thingy.indexOf("ABC") == 0) { // if it starts with ABC
			arr.push(window[thingy]);
		}
	}
	alert(arr.join("\n"));
}
</script>
</head>
<body>
</body>
</html>

jimfraser,

What does your code do that the following doesn't do:

arr = [ABC_x, ABC_y, ABC_a, ABC_b];

Although the poster now says that is not what he wants to do. He wants the actual text:

"var ABC_x = 112"

Hmm... that appears to be a bug in IE. It works fine in Firefox and Opera.

The alerts display the values, but it appears that with the former declaration, the variable fails to show up in a for-in loop but the latter does.

Code:

var ABC_x = "112";
window["ABC_y"] = "184";
alert('ABC_x = '+window["ABC_x"]);
alert('ABC_y = '+window["ABC_y"]);
for (var thingy in window) {
  if(typeof(window[thingy])!='string') continue;
  if(!confirm(thingy)) break;
}

When I read the original post I figured that the point was to take an unknown quantity of variables (in this case ABC_x et al) that are loaded separately (in a.js, b.js) and somehow make an array of their values, allowing for expansion later on (eg ABC_z = "555").

I thought that using window["variable_name"] would work, but for some reason those variables didn't show up in my for...in loop, unless they were defined as I showed in my example.

This code:
arr = [ABC_x, ABC_y, ABC_a, ABC_b];
sure it works fine, but not if ABC_z and ABC_c are added later.
