Problem in calling javascript function

[subhasish nag]

Hi Ranchers,
I have a problem.
want to call a function to set a jsp field dynamically
the function is

     function getCertificateNo(str){
      if(trim(str).length>0){
         var str1=<%=Integer.parseInt((session.getAttribute("certNo")).toString())%>+1;
         alert("str1"+str1);
          document.getElementByName('certificateNo').value=str1;
      }
   }   

I am unable to call the function as I 'm unable to pass the right argumenty.

  	 <%    int loop_ctr=0; %>
  				<logic-el:iterate  collection="${OMPOpenCoverCertificateForm.empInfoList}" id="empInfoList" indexId="ctr">

			    <tr>
  <td><center><html:text name="empInfoList" property="empId" indexed="true" onchange="<%=val%>" size="10" maxlength="4" /></center></td>
  <td><center><html:text name="empInfoList" property="certificateNo" indexed="true" maxlength="14" readonly="true" /></center></td>
                     <%     loop_ctr=loop_ctr+1; %>
                </tr>
                </logic-el:iterate>

     

Can anybody pl guide how to call the function properly and set the value for the field

A couple of things.

Firstly, this is an HTML forum, not a Struts forum. Posting code with Struts tags in it isn't a great idea as most people won't know what they mean. Please show only the real HTML code.

Your code also has a lot of formatting problems that makes it hard to read.

Secondly, please use real words when posting to the forums. Abbreviations such as "pl" in place of "please" only serve to make your posts more difficult to read and less likely to generate useful responses.

Please read this for more information.

thanks,

getCertificateNo - from your html code, we do not see any invocation of this function. You said you are not able to call this function with correct arguments; can you show how you are calling it.

I think onchange() should call a javascript function (probably the one you posted:
onchange="getCertificateNo(<%=var%>)" ).

And you might want to explain/show more for us to understand better.

Seeing serverside markup does not help, we need to see examples on what gets rendered.

Gavi jadz Grandea,

Please be sure to use code tags to display code in your posts rather than green text (which is hard to see against the tab background on many monitors).
