For loop error - object expected

#1 July 23rd, 2005, 08:52 PM

When I run page I immediatley get "Object expected" message and the tag
<body onload="setfocus()" is highlighted.

The error occurs in this snippet from within the script file

function validatePage()
{
// select the items in the TeamDivisions listbox
var i=document.TeamMaintenance.TeamDivisions.options.l ength -1
For (i; i>=0; i--)
{document.TeamMaintenance.hiddenTeamDivisions.valu e +=
document.TeamMaintenance.TeamDivisions.options[i].value;
document.TeamMaintenance.hiddenTeamDivisions.value += ",";}

// Now validate the page
return validatePanels();
}

I know this because if I comment out the line "For (i; i>=0;i--)", the
functions within the script file work correctly. Obviosusly in the
above snippet the 2 lines to be executed within the For loop executes
the once but I get the expected value in the hiddenTeamDivisions
control so at least it shows that these lines do work.
The problem is why do I get the "object expected" message when this
line is not commented out?

Thanks in anticipation

The keyword is "for", not "For".

Try this:

// select the items in the TeamDivisions listbox
var x = [];
var f = document.TeamMaintenance.TeamDivisions.options;
var i = f.length;
while (i--){ x.push(f[i].value) }
document.TeamMaintenance.hiddenTeamDivisions.value = x.join(',');
