Question

i am trying to pass parameter value from one javascript function to another.

From Below Code: i am passing two values from function formatLink to function openDialog .But only the first value(cellvalue) is passing correctly but the send value (para) is not passing .
Why i it is not passing to function openDialog?
Please help me

 <script type="text/javascript">

    function formatLink(cellvalue, options, rowObject)
    {
         var para=image.jpg; 
         return "<a style='cursor:pointer;' onClick='javascript:openDialog("+cellvalue+"),("+para+")'><img width='63' height='25' src='<s:url action='ImageAction' namespace='/myimage/secure'></s:url>" + "?imageId="+para+ "'></a>";
      }

    function openDialog(cellvalue,para) { 
        alert(para);//this is coming as undefine
            alert(cellvalue);//& this values is coming correctly

         //below diaologbox id is given to open
             $("#employees_details").load("<s:property value="loadformurl"/>?themeid="+employee);
            $("#employees_details").dialog('open');
    }

You have some extra parentheses in your generated function call:

change

return "<a style='cursor:pointer;' onClick='javascript:openDialog("+cellvalue+"), ("+para+")'><img width='63' height='25' src='<s:url action='ImageAction' namespace='/myimage/secure'></s:url>" + "?imageId="+para+ "'></a>";

to

return "<a style='cursor:pointer;' onClick='openDialog(\'"+cellvalue+"\', \'"+para+"\')'><img width='63' height='25' src='<s:url action='ImageAction' namespace='/myimage/secure'></s:url>" + "?imageId="+para+ "'></a>";

Notice, I removed the ending and beginning parentheses in the onClick handler and fixed some quotes:

onClick='openDialog(\'"+cellvalue+"\', \'"+para+"\')'
