how to prevent postback using jquery


$(document).ready(function () { $("#Div_1").show(); $("#Div_2").hide(); $('#Buttion1').click(function () { $("#Div_1").hide(); $("#Div_2").show(); }); });

in the above code, while loading is working but when click (Buttion1 is ASP.Net Server button) on button Div_2 not showing off and Div_1 not hiding off


$('#Buttion1').click(function () { $("#Div_1").hide(); $("#Div_2").show(); return false;



Here is the correct way to do it.

Eg: <a href="http://jsfiddle.net/vtLMT/" rel="nofollow">http://jsfiddle.net/vtLMT/</a>


<div id="div1">Div1</div> <div id="div2">Div2</div> <button id="btn">Click Me</button>


#div1 { } #div2 { display: none; }


$(document).ready(function() { $("#btn").click(function() { $("#div1").hide(); $("#div2").show(); return false; }); });


try this

$(document).ready(function () { $("#Div_1").show(); $("#Div_2").hide(); $('#Buttion1').click(function () { $("#Div_1").hide(); $("#Div_2").show(); return false; }); });


<asp:UpdatePanel runat="server"> <ContentTemplate> <asp:Button Text="text" ID="Buttion1" OnClientClick="hideshow();" runat="server" OnClick="Buttion1_Click" /> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="Buttion1" EventName="Click" /> </Triggers> </asp:UpdatePanel> <div id="Div_1"> </div> <div id="Div_2"> </div> <script type="text/javascript"> $(document).ready(function () { $(document).ready(function () { $("#Div_1").show(); $("#Div_2").hide(); }); }) function hideshow() { $("#Div_1").hide(); $("#Div_2").show(); return true; } </script>

server side code

protected void Buttion1_Click(object sender, EventArgs e) { //server side code }


1)your two div must be out side updatepanel.

2)your hideshow function must not be undefined.Place function on at the en of the page

3)on button client click call hideshow function which return true

4) after javascript function return true..it goes for the server side event
