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>
-

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;
-
regards
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. -

function initializeVars(){

for (var j=0; j<comboAll[i].length;j++){

comboAll[i][j] = 'Hello ' + j ;

}

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

you don’t. what you’re setting is the comboAll variable, not a to f.
@Dormilich
Indeed thanks for your answers.
Then how do I assign values during the loop to those variables from a to f?
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)
