What is the reason for the inability to debug the JavaScript function from an ASPX file?

I need to insert a debug point in my JavaScript function within the ASPX source file. However, when I write the keyword "debugger" inside the function and click the update button, the debugger is not being triggered.

All I want is for the debugger in the JavaScript function to be activated when I click the update button.

<script type="text/javascript" lang="javascript">

        function update() {

            debugger;

            if (document.getElementById('<%=TxtRStateName.ClientID%>').value == "") {
                alert("Please Enter State Name");
                document.getElementById("cphContentBody_TxtRStateName").focus();
                return false;
            }

            if (!isNaN(document.getElementById("cphContentBody_TxtRStateName").value)) {
                alert("Please Enter Character");
                document.getElementById("cphContentBody_TxtRStateName").value = ""
                document.getElementById("cphContentBody_TxtRStateName").focus();
                return false;
            }
            if (document.getElementById("cphContentBody_ImgBtnUpdate").value == "") {
                if (confirm("Do you want to Update?"))

                    return true;
                else
                    return false;
            }
            else
                return false;

        }
    </script>

  • In the world of Internet Explorer 8, nothing beats Developer Tools - F12.
  • For Firefox and Firebug lovers, simply hit F12 to display.
  • Safari enthusiasts can access the Develop menu bar through Show Menu Bar under Preferences -> Advanced.
  • Google Chrome users can open the JavaScript Console by pressing F12 or (Ctrl + Shift + J). Some may argue that Safari is superior to Chrome.
  • Opera fans can find Developer Tools under Tools -> Advanced.
