Trigger the change event of a textbox in jQuery
- by Danny Chen
I have an asp:TextBox with asp:RegularExpressionValidator to validate if it's a number. Obviously an onchange event will be attached to this textbox while rendering. Also I add a change event at $(document).ready to make some calculation when the value is changed.
<asp:TextBox id="myText" runat="server" />
<asp:regularexpressionvalidator id="myRev" ControlToValidate="myText" runat="server">*</asp:regularexpressionvalidator>
$(document).ready(function(){
$('[id$=myText]').bind('change',function(){
//do something
}).change(); //force the change event at the very beginning
});
My function will be executed later than the .net generated js because of the register time. But the .net js throws an error. I traced in the js:
function ValidatorOnChange(event) {
...
}
and found that all of event.fromElement,event.toElement,event.srcElement are null which causes the exception. Did I do something wrong? Any solutions? Thanks.
