jQuery .onsubmit不會觸發

Question

自幾個小時以來，我就遇到問題了。 我想在驗證之前觸發.submit事件並進行測試。 但是當我調試時是否在$（“＃btnSub”）。submit上放置一個斷點，它可以檢測到但只是不執行代碼就結束了。

//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;
    }
});

如果您能給我一些線索，那將是非常好（激怒）（我知道該代碼有效，因為在我使用.click事件之前，沒有，我沒有忘記提交表單和按鈕類型提交）謝謝！

根據注釋，出現此問題是因為您將onsubmit事件綁定到Submit按鈕，但是沒有此類事件按鈕。

onsubmit事件是HTMLFormElement的事件，因此您需要選擇表單並監聽其事件：

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