jquery.onsubmit 不触发

Question

我几个小时以来因为问题被屏蔽了。我想触发 .submit 事件并在验证之前进行测试。但是当我调试时，如果我在 $("#btnSub").submit 上放置一个断点，它会检测到但只是结束而不执行我的代码。

//on submit
//_________________________________________________________
$('#btnSubs').submit(function(e) {
    //Check if form is already shown
    if ($('#collapseState').val() === "true") {
        //Check content before send
        //--------------------------------------------------------------------------------------------------------------------------------------
        var valid = (chckPseudo() === true) && (chckMail() === true) && (chckMail2() === true) && (chckPWD() === true); //define a valid flag

        if (valid) {
                 //disable the btn to avoid multiple connections
                $(this).button('loading');
               //submit the form
               return true;
        } else {
            if (chckPseudo())
                formValidate("grpPseudo", "correct");
            else
                formValidate("grpPseudo", "incorrect");

            if (chckMail())
                formValidate("grpMail", "correct");
            else
                formValidate("grpMail", "incorrect");
            if (chckMail2())
                formValidate("grpMail2", "correct");
            else
                formValidate("grpMail2", "incorrect");


            if (chckPWD())
                formValidate("grpPSW", "correct");
            else
                formValidate("grpPSW", "incorrect");  
            //dont submit
            e.preventDefault();
            return false;
        }

    }
    //show form
    else {
        $('#collapseSubscribe').collapse('show');
        $('#collapseState').val("true");
        // don't submit the form
        e.preventDefault(); 
        return false;
    }
});

如果你能给我一些线索，那将非常非常友好（恼怒）（我知道代码有效，因为在我使用 .click 事件之前，不，我没有忘记提交表单和按钮类型）谢谢！！

根据评论，问题出现是因为你绑定了onsubmit事件提交按钮，但是没有这样的事件按钮。

onsubmit 事件是 HTMLFormElement 的一个事件，所以你需要select你的表单并监听它的事件：

$('form').submit(function() {
    // your code
});
