做登錄界面的時候發(fā)現(xiàn)有時候點擊登錄按鈕頁面無響應，要重新加載一遍網(wǎng)頁證書才能登錄，請問這有什么好的解決辦法嗎？網(wǎng)上有人說網(wǎng)絡(luò)太差也會出現(xiàn)這樣的情況

var validate2 = $("#form2").validate({
                /*自定義驗證規(guī)則*/
                debug: true,
                rules: {
                    username: {
                        required: true,
                    },
                    password: {
                        required: true,
                    },
                },
                messages: {
                    username: {
                        required: '請輸入用戶名',
                    },
                    password: {
                        required: '請輸入密碼',
                    }
                },
                errorPlacement: function (error, element) {
                    error.appendTo(element.parent().next());
                },
                submitHandler: function (form) {
                    var userName = $("[name|='username']").val();
                    var passWord = $("[name|='password']").val();                    
                     loginByUserName(userName, passWord);
                }
            });

...部分刪減 太長了
function loginByUserName(userName, passWord) {
            loginMagByUserName.param.userNameOrPhone = userName;
            loginMagByUserName.param.password = passWord;
            $.postJSON("LoginByPassword", loginMagByUserName, function (ajaxData) {
                if (ajaxData.head.code === "C2000") {
                    localStorage.token = ajaxData.head.token;
                    location.href="main.html"
                } else {
                    $("#error2").append("<label class='error'>用戶名或密碼錯誤</label>");
                }
            });
        }
