Question

I am using onkeyup function in a textbox to make a button click but when I click on enter first on TextBox cursor moving to next line and then onkeyup function is taking place. For perfection in my project I need quick onkeyup function where cursor should not go down and function should take place. Just like StackOverflow’s comment TextBox.

I am using following code:

<asp:TextBox ID="inputmess" runat="server" TextMode="MultiLine" Height="70px" Width="495px" onkeyup="if (event.keyCode == 13) document.getElementById('sendmess').click()" />

Answer 1

Use keydown instead of keyup and return false;.

onkeydown="if (event.keyCode == 13){ document.getElementById('sendmess').click(); return false;}"

Another alternative:

onkeypress="if (event.keyCode == 13){ document.getElementById('sendmess').click(); event.preventDefault();}"
