array of arrays - assigning values to variables inside array !

[hash4sp]

Hi,

Can anyone please advise me on the following. Here I have a bunch of variables in an array. And then those arrays in another array. I want to assign values to those variables in arrays. Is this the correct way to do it?

<html>
<body>

<script type="text/javascript">

var a,b,c,d,e,f;
var set1=[a,b,c];
var set2=[d,e,f];
var comboAll=[set1,set2];

function initializeVars(){
	
	for (var i=0; i<comboAll.length;i++){
			
		for (var j=0; j<comboAll[i].length;j++){
			comboAll[i][j] = 'Hello ' + j ;
		}	
	}	

	document.write('Start wrting variables<br />');	
	document.write(a + '<br />');
	document.write(b + '<br />');
	document.write(c + '<br />');
	document.write(d + '<br />');
	document.write(e + '<br />');
	document.write(f + '<br />');

	
}

</script>

</body>
<input type='button' value='Initilize' onClick='initializeVars();' />
</html>

Best regards

first, don’t use document.write( ) after the page finished loading.

I changed it with a DIV tag. Still doesnt work.
It returns undefined for each variable.

<div id='results'></div>

document.getElementById('results').innerHTML = a + ' ' + b + ' ' + c + ' ' + d + ' ' + e + ' ' + f;

of course, you never set them anywhere.

Thanks for you reply. I am setting the values for the array variables in the loop. Am i doing something wrong here.

<html>
<body>
 
<script type="text/javascript">
 
var a,b,c,d,e,f;
var set1=[a,b,c];
var set2=[d,e,f];
var comboAll=[set1,set2];
 
function initializeVars(){
 
    for (var i=0; i<comboAll.length;i++){
 
        for (var j=0; j<comboAll[i].length;j++){
            comboAll[i][j] = 'Hello ' + j ;
        }    
    }    
 
document.getElementById('results').innerHTML = a + ' ' + b + ' ' + c + ' ' + d + ' ' + e + ' ' + f;
 
 
 
}
 
</script>
 
</body>
<input type='button' value='Initilize' onClick='initializeVars();' />
<div id='results'></div>
</html>

[Dormilich]

you don’t. what you’re setting is the comboAll variable, not a to f.

Indeed thanks for your answers.
Then how do I assign values during the loop to those variables from a to f?

[Dormilich]

you cannot. you would have to assign a to f manually.

you should better think of a way, to tweak the output (admittedly, you have a very abstract example)
