javascript 使用字段值进行表单跟踪（未经测试）

Posted 2021-05-03

$("#form_id").submit(function(e) {
    var form = $(this).get(0),
        submitted = false;
        
    function submit_form() {
        if (!submitted) {
            document.createElement('form').submit.call(form);
            submitted = true;
        }
    }

    mpq.track("Form submitted", { 
        name: $(this).find(".name").val(),
        email: $(this).find(".email").val()
    }, submit_form);
    
    // set a timeout just in case our tracking call takes too long
    setTimeout(submit_form, 500);
    
    e.returnValue = false;
    if (e.preventDefault !== undefined) { e.preventDefault(); }
});
