Question

I have the following inline code that I can’t change due is outputted by a foreigner plugin. Contain a onclick handler that trigger the submit event:

<input type='button' id='gform_next_button_12_188' 
class='button gform_next_button' value='Next' tabindex='3' 
onclick='jQuery("#gform_target_page_number_12").val("2"); jQuery("#gform_12").trigger("submit",[true]); '/> 

I want to run some routines before submit the form and I tried this:

$("#gform_12").submit(function(e){

    // this code is not running ...

});

That it is failing, ie, my code is not running when form is submitted . Any suggest?

Final solution based on answers given

var inline_onclick_code_on_next = $(".gform_next_button").first().attr("onclick");
$(".gform_next_button").removeAttr("onclick");
$(".gform_next_button").bind("click", function() {
    myClass.autosave_on_click(inline_onclick_code_on_next);
});

myClass = {
    errorMessage : "",
    autosave_on_click: function (inline_onclick_code){
        my_gravity_form_saving_running = 1;
        myClass.saveData(); // this code must put my_gravity_form_saving_running = 0 when all data be saved
        countdown_max_loop = 10; // seconds
        var countdown = window.setInterval(function(){
            if (countdown_max_loop-- == 0 || my_gravity_form_saving_running == 0){
                clearInterval(countdown);
                eval (inline_onclick_code);
            }
        }, 1000);
    }
}

Try to unbind the click event from the element and then specify your own.

$('#gform_next_button_12_188').unbind('click').removeAttr('onclick');
$('#gform_next_button_12_188').bind('click', function() {
    // do magic stuff

    // do the rest
    jQuery("#gform_target_page_number_12").val("2");
    jQuery("#gform_12").trigger("submit",[true]); 
});

Edit:

added removeAttr, thanks @gdoron
