Hi,

I am using the javascript in my application. I want to change the value of the label as yes or no based on the value entered in the text box and checking the condition in the label. Here is the script I am using in my application:

XML

<script language="javascript" type="text/javascript" >
     function TextChange() {
         var ProjectValue = document.getElementById('<%=txtApproxBidVal.ClientID%>').value;
         var Param = document.getElementById("<%= lblCondition.ClientID %>").innerHTML;
         if (parseInt(ProjectValue.value) > Param.innerHTML)
         {
             var yesnotext = document.getElementById("<%= lblYesNo.ClientID %>").innerHTML;
              yesnotext.value ="Yes";
          }
          else if (parseInt(ProjectValue.value) < Param.innerHTML)
          {
              var yesnotext = document.getElementById("<%= lblYesNo.ClientID %>").innerHTML;
              yesnotext.value = "No";
          }
     }
     </script>

Is there any changes in this code. Can any one help me to solve this problem.

Thanks in Advance

Why didn't you parse the right side values?

JavaScript

if (parseInt(ProjectValue.value) > parseInt(Param.innerHTML)) { }

I tried in that way also but its not going inside the condition if the condition is true or false

Check the value of ProjectValue.value & Param.innerHTML. Validate if those values are non-numeric. Use isNaN for that

JavaScript

function TextChange() 
{
        if (eval(document.getElementById("txtApproxBidVal").value) > eval(document.getElementById("lblYesNo").innerHTML))
        {
             document.getElementById("lblYesNo").innerHTML="Yes";
         }
         else
         {
             document.getElementById("lblYesNo").innerHTML = "No";
         }
    }

XML

<script language="javascript" type="text/javascript" >
     function TextChange() {
         var ProjectValue = document.getElementById('<%=txtApproxBidVal.ClientID%>');
         var Param = document.getElementById("<%= lblCondition.ClientID %>");
 var yesnotext = document.getElementById("<%= lblYesNo.ClientID %>");

         if (parseInt(ProjectValue.value) > parseInt(Param.innerText))
         {
                          yesnotext.innerHTML="Yes";
          }
          else if (parseInt(ProjectValue.value) < parseInt(Param.innerText))
          {
                            yesnotext.innerHTML= "No";
          }
     }
     </script>

Hope this helps.
