JavaScript单击Asp.net输入Enter呼叫按钮提交

Question

I have created this javascript.

<script type="text/javascript">
 function handle(e)
   {
    if (e.which == 13 || e.keyCode == 13)
     alert("The enter was pressed");
    }

</script>

And I have few text box, which I expected when I click enter, I will call button submit.

<asp:Textbox id="txtClient" Runat="Server" Width="252px"/>
<asp:Textbox id="txtDescription" Runat="Server" Width="252px"/>

<asp:Button ID="btnRegister" runat="server" Height="22px" Text="Enter" Width="100px" />

But I still cannot display the message box, can someone show me how to handle and call button submit?

Here you go

DEMO HERE

$('input').on('keypress',function(e){
    if(e.which == 10 || e.which == 13) {
        alert('hit');
    }
});

UPDATE

Add this in your text box and call a function:

<asp:Textbox id="txtClient" Runat="Server" Width="252px" onkeypress="checkEnter(event)"/>

function checkEnter(ev)
{
        if(ev.which == 10 || ev.which == 13) {
        alert('hit');
    }
}
