I am developing a web application using JSP and Servlet.

I am trying to call javascript function on the click event of hyperlink, and with that I am also passing some parameters to servlet using query string.

<td> <a href=#?id=<%=data[i][0]%>&protID=<%=data[i][1]%>&seqNo=<%=data[i][2]%> onclick=getValues(); >Edit</a></td>

javascript function:

<script>

function getValues()

{

    var url = document.URL;

    var planID = url.split(=);

    var pID = planID[1].split(&);



    var remURI = url.split(&);

    var protID = remURI[1].split(=);



    var s = remURI[2].split(=);



    document.getElementById('txtPlanID').value=pID[0];

    document.getElementById('txtProtID').value=protID[1];

    document.getElementById('txtSeqNo').value=s[1];



//show(block);

return false;

}

</script>

But the problem is that I have to click twice on hyperlink to get desired result.
I think onClick event is executing before sending query string.
Please let me know if there is anything wrong in source code.

Thanks in advance.....
