I am trying to prevent unintended submissions of a form when the Enter key is accidentally pressed. I tried in abject futility to block the Enter key - code 13 and 10 - so am revisiting a simple confirmation popup. The code I have works - if Enter is pressed or Submit button clicked, it does create a pop-up. If I click OK, it submits the form as expected. But if I click Cancel, it hangs the form altogether. Displays a faded version of the form and all data typed in it, that is completely unresponsive. The only way to get the form to work again is to refresh the document, which deletes everything entered. Any ideas? Here are two options I tried - both exhibits identical results:
​

jQuery('#display-section1').submit(function() {
    var status = confirm("Click OK to Submit?");
    if(status == false){
        return false;
    } else {
        return true; 
    }
});

jQuery(document).submit(function() {
    var status = confirm("Click OK to Submit?");
    if(status == false){
        return false;
    } else {
        return true; 
    }
});

I get the same results if I try something like this too. I want it to go back to the form with the data intact so the user can finish it, or correct it before submitting again:
​

jQuery('#display-section1').submit(function() {
    var c = confirm("Click OK to continue?");
    return c;
});

Bob is correct.

I left the submit button alone as it normally is (there is no disable setting).
​
Instead, if you have a checkbox "agree to terms" or whatever just above the submit button, go in and create a "select" event to enable and "unselect" event to disables the submit button.
​
When your form loads the checkbox is unchecked so the submit button will be disabled with have a 50% or so color discoloration-transparency. When you check the checkbox, the the button turns to normal color and can submit.

Thanks. I just did the checkbox method on one form, and inserted a blank space at the top of a drop-down on another form. Both methods work great.

Hi ipates,
​
Instead of a blank space at the top of the drop-down you can use a line with no value e.g. =Please choose
