asp.net button click not working

Question

I have a JavaScript code and an asp.net button control , javascript code is working fine but the asp.net button is not working for that js script

<asp:Button ID="loginbtn" CssClass="btn-glow primary login" OnClientClick="abc(); return false;" runat="server" Text="log in" OnClick="loginbtn_Click" />

Answer 1

Because you have return false in your OnClientClick. Remove it an the button will post back.

• mgmedick: Yes this ^ the client side code runs first, so your onClientClick is running before your OnClick, thus preventing the post back, because you're returning false.

Answer 2

please change the code like this

 <asp:Button ID="loginbtn" OnClientClick="abc();" runat="server" Text="log in" OnClick="loginbtn_Click"/>
 function abc() {
 alert("Hi"); //put your code here
 return false;
 }

or

 function abc() {
 alert("Hi"); //put your code here 
 }

both will work.

Answer 3

Convert your asp.net button to input button to prevent callback and make an ajax function call.

<input type="button" class="btn-glow primary login" onClick="abc()"/> 
function abc(){
 //ajax call
}

Answer 4

replace

OnClick="loginbtn_Click"

with

OnClick="loginbtn_Click()"
