Question

I have a button in my form. I need my form to be processed after the first click (or pressing Enter) on the button, and after that, if some conditions would be true, I do something like submitting the form by the second click or pressing Enter key on the button.

What do you think I have to do?

Answer 1

Create a (boolean) variable that saves your state, which is set to true when the first click (or action) has happened and your condition is true. Then submit on the second action when the variable is true.

If the condition has to be matched on both clicks (I guess so) consider the following:

$(function() {
    var first = false;
    $("form").submit(function() {
        if(first && checkCondition())
            submit();
        if(!first && checkCondition())
            first = true;
        e.preventDefault();
    });
});
