Here I would like to share code and process to call server
side from the javascript. But in many cases we need to call any event method
from javascript,In such cases I hope this article would help to resolve your
process.
Initially you can call server side method event by two
method of code. Here I illustrate with proper example to when we need to call
method event using javascript.
Scenario 1;
Take as scenario in textbox when user enter text after the
completion when users press enter key, you need to call the method in server
side.
|
<asp:TextBox ID="TextBox1"
runat="server" onkeypress="return EnterEvent(event)"></asp:TextBox>
<asp:Button ID="Button3" runat="server" style="display:none" Text="Button" />
|
In javascript we need to write a function enter event to
call server side code button event.
|
<script type="text/javascript">
function
EnterEvent(e) {
if (e.keyCode == 13) {
__doPostBack('<%=Button3.ClientID%>', "");
}
}
</script>
|
So when user press enter key it will call the button3 server
side code event.
Scenario 2:
Also we can call server side code by another using this anther
way i.e.
|
function
caller(){
document.getElementById('<%= Button3.ClientID %>').click();
}
|
By using above code have alternate way to call server side
from javascript.
