value of variable not as expected

for (var i = 0; i < 10; i++)
{
$j = _heading4(i).innerHTML;
_alert($j);
_writeFile($j,"foo.txt");
}

For the previous example, the _alert() shows the value I expected (in this case an html anchor tag and end-tag) but what is written to the file "foo.txt" is "_sahi._heading4(0).innerHTML" (0 through 9).

Can anyone help me understand the difference?

Thank you very much,
James

    Hi James,

    While working with for loop in Sahi we have to make sure that we "do not use a condition which depends on a page’s DOM". For more Details regarding for loop:

    http://sahi.co.in/w/for-loops

    Use the following script:
    var $headingList = [];
<browser>
function getNoofheading(){
    var retVal = [];
    var headings = document.getElementsByTagName("h4");
    for (var i=0; i<headings.length; i++){
        retVal[i] = headings[i].innerHTML;
        
    }
    return retVal;
}
</browser>
_set($headingList, _call(getNoofheading()));

for (var $i = 0; $i <$headingList.length; $i++)
{
    var $j = $headingList[$i];    
    _writeFile($j + "\r\n","foo.txt");
}

    Thank you Sumitra. I reread the for-loops page which explained the process. I appreciate your reply.
