jQuery: Checkbox Validation Alert

Hi there,

I am new to jQuery and am having some troubles with validation.  I have a checkbox to agree to our policy and I want an alert(); to happen if the user submits the page without having checked it.  Right now it will display an text message on the page if they haven't checked the checkbox, which I want, but I also want that alert() to happen.

What am I doing wrong?  The below code doesn't function at all, but how would I change it to get the desired effect?

Thanks.
jQuery.validator.addMethod("agree", function(value, element) {
	if ($('#TERMSAGREEMENT').val() != "on") { 
alert("Please click to agree."); }	
			
	}, "");

....

<input name='terms' id='terms' class="required agree"  type='checkbox'>

Shouldn't #TERMSAGREEMENT be terms?

Sorry, I was trying to clean it up so it was shorter :-).  Yes - #TERMSAGREEMENT should be terms.  But it still doesn't work :-).

Sorry about that :-).
jQuery.validator.addMethod("agree", function(value, element) {
	if ($('#terms').val() != "on") { 
alert("Please click to agree."); }	
			
	}, "");

....

<input name='terms' id='terms' class="required agree"  type='checkbox'>

The three most common changes you will make to your website involve the look (themes), the functionality (plugins), and modular elements (widgets).

Well, in "normal" JavaScript:
function test_it() {
    var val = document.getElementById("terms").checked;
    
    if (val == "checked") {
        // True
    }
    else {
        // False
    }
}

Yes, I was able to get that much working, but I am trying to get this to work under jQuery as I described above.

You might try
if ($('#terms').checked() != "checked") {

I have tried that, it still doesn't come up with the alert being displayed on submit if terms is unchecked.

In the following
jQuery.validator.addMethod("agree", function(value, element) {

Open in new window

what are value and element? Perhaps their values can help?

I tried to cancel this question but you kept it open, I was not looking for a JavaScript solution, so I was trying to re-post this in the right category.  I did so and got the answer I was looking for.
