        if($("#Label1").val()=="1"){
		$("#popupCon").css({
			"opacity": "0.7"

try like this

JavaScript

<script type="text/javascript">
  //$(document).ready(function() {
        if($("#Label1").html()=="1"){
		$("#popupCon").css("opacity","0.7");
       }       
    </script></script>

but remember if you are using master page then the IDs for popupCon and Label1 may be different, like ctl00_ContentBody_Label1 etc, please confirm and use.
