another js one - Array Q

[alex_read]

Function CreateInitialArray() {
    var intCounter;
    var strTemp;

    for(intCounter=0; intCounter<theform.lstbox.options.length; intCounter++) {
        strAry[intCounter] = theform.lstbox.options[intCounter].text;
        strTemp = strTemp + strAry[intCounter] + "\n";
    }		
    alert(strTemp);
}

Hi all. I'm using that one to loop through a <Select> listbox on a web page, and adding each line or entry from this listbox into an array. A string's then created of all the array elements before showing this in a messagebox.

I keep getting "undefined" before the first entry though - below is an example of how this comes out. Whats the reasoning behind this please ?!?!? :

UndefinedOne
Two
Three

*shrug*

Try setting strTemp to and empty string before the loop.

I don't guess JavaScript has a += operator.

Yeah, that did it, thanks !
