$('[id$=btnYes]').click(); Am not getting the $ sign in the selector?

Brian A Stephens 24-Apr-13 8:23am

The $ in the selector indicates that the id attribute should END with the given value, rather than being equal. It's one approach when using ASP.NET web forms, which generate their own IDs on the fly.

Add preventDefault() in your code

Hi Yvonne192,

JavaScript

OnClientClick="return(cfrm());"

should be

JavaScript

OnClientClick="return cfrm();"

in the Button tags.

Please modify and click the solved button if this helped you.

Thank you,
Vamsi

Are you using jquery and if so and if you kept this in ready method

$(document).ready() or jQuery(document).ready()

then anything within the ready() function will only be called once - when the page is loaded. It waits until the entire DOM is loaded before executing that code.

Try to keep that function outside of that and let me know about it.

Brian A Stephens 24-Apr-13 8:31am

[In reply to mvamsianil] Yes, she is using jQuery (notice the jQuery selectors in the code). jQuery code should generally be inside a document.ready callback (I'm not sure whether this is), but I don't understand your comment. The code that DEFINES the function will be run only once whether it's in a document.ready or not - it's just the timing of the definition that would change. The click event should call the function every time.

Have you debugged in the browser to step through and see what's happening?

Hi,why not your code use jQuery completely ?
try this

JavaScript

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
	$(function(){
		$("#btnCalculate").click(function(){
			var consultFee = $('[id$=txtConsultFee]').val();
			//consultFee=600;
			if(consultFee>500){
				if(confirm('Confirm?')){
					alert(123);
					// do something;
				}else{
					alert(456);
					//do something;
				}
			}
			return false;
		});
	})
</script>
<asp:button id="btnCalculate" runat="server" text="Calculate Claim" xmlns:asp="#unknown" />
