jQuery intercept form submission

I have number of conditions i'd like to check before submitting a form so I've created:

$("Step2_UpdateCartForm").submit(function () {
    if (!procssingEmails) {

        return true;
    } else {
        return false;
    }

And I have a number of events that could result in a form submission so i have something like:

function fireUpdateCart() {
    if (isUpdateCartPending) {
        clearCartOptio开发者_如何学PythonnDefaultValues();
        $("#Step2_UpdateCartForm").submit();
    }
}

in a few different places. I'm expecting the above statement to send processing to that first code block but instead, the form is being submitted.

Am i wrong to expect my validation block to be processed

You are missing a "#" identifier from your event definition. This is the likely cause of your problem. The first line should read:

$("#Step2_UpdateCartForm").submit(function () {

   ^

There's a missing # in your selector. You should use the following:

$("#Step2_UpdateCartForm").submit(function () {
    if (!procssingEmails) {

        return true;
    } else {
        return false;
    }

And BTW, maybe your "procssingEmails" is misspelled, isn't it?
