Hi &nbsp;&nbsp;&nbsp;I was trying to call a javascript function.I have text areas like transfer\_reason1 transfer\_reason2 etc in each divs div number is available as variable div\_no in the page..How can I pass the textarea content to the javascript..Below I tried like get\_primary\_assignees\_transfer\_reason($('transfer\_reason+eval(#{div\_no}))').value )

How can I evaluate the above to get get\_primary\_assignees\_transfer\_reason($('transfer\_reason1').value ) get\_primary\_assignees\_transfer\_reason($('transfer\_reason2').value ) etc But not working.Please help

Sijo

assuming div\_no is a javascript variable, that should be $ ('transfer\_reason' + div\_no)
