Question

What I am trying to accomplish is a (very simple) email validation using jQuery, but no matter what I do, the form will just keep submitting.

<form id="rfq" name="rfq" action="rfq_form" method="post" enctype="multipart/form-data">
…

<input type="image" id="submit" name="submit" src="submit.png" border="0" />

JS email validation:

//$("#rfq").submit(function() { doesnt seem to work either

$('#submit').click(function() {
    var email = $('#email').val();
    if(email.indexOf("@") == -1){
        $("#email").addClass('invalid');
        return false; // cancel form submission if email invalid
    }
    return false; // return true if no errors once i get it working
});

Working Example

First, make sure all event handlers are attached once the DOM is “ready”

I’m using .submit() on the actual form.

$(document).ready(function() {
    // now that document is "ready"
    $('#formId').submit(function() {
        var email = $('#emailInput').val();
        alert(email);
        if(email.indexOf("@") == -1){
            alert("invalid!");
            return false; // cancel form submission if email invalid
        }
        alert("valid!");
        return true; // return true if no errors once i get it working 
    });
});
