如何通过javascript区分按钮单击和按钮单击

Question

I click submit button before test time is completed So I show a confirm message "Do you want to really Quit this test" and I click the submit button when Time is completed (Time left is 00:00:00) through javascript, but then also it asks user with confirm message Which I do not want to show on completion of time, How can I achieve this? This is my button

<asp:Button ID="btnSubmit"  class="btn" runat="server"
                                    OnClientClick="return confirm('Do you  want to really Quit this test');" Text="Submit Test"
                                    OnClick="btnSubmit_Click" />

This is javascript through which I call Click event when test time is over

<script type="text/javascript">
         function 
    display() {

                var hours = document.getElementById('<%=HidH.ClientID %>');
                var minutes = document.getElementById('<%=HidM.ClientID %>');
                var seconds = document.getElementById('<%=HidS.ClientID %>');

                if (hours.value == 0 && minutes.value == 0 && seconds.value == 0) {
                    alert("Time Given For this Test is Over");
                    document.getElementById('btnSubmit').click();
                 }
                } 
   </script>

Instead of binding click event inline call a function where you will prompt user for confirmation and make it option depending on timeout.

Change

OnClientClick="return confirm('Do you  want to really Quit this test');" 

To

OnClientClick="return myConfirmFun()" 

Define myConfirmFun as under.

var showConfirm = false; // defind gloablly

function myConfirmFun()
{
    if(showConfirm) 
    {
        showConfirmm = false; 
        confirm('Do you  want to really Quit this test');
    }
}

In the display function

if (hours.value == 0 && minutes.value == 0 && seconds.value == 0) {
    showConfirm = false;
    alert("Time Given For this Test is Over");
}
else
    showConfirm = true;
