jQuery验证表单隐藏显示不起作用

Question

我正在使用jQuery Validate插件来验证表单，但是每次我提交表单时，页面都会重定向到操作页面。我不仅要验证表单，还要在知道表单无错误后尝试使用ajax提交表单。

这是我用于自定义JS编码的javascript文件。

<script type="text/javascript">
    $(document).ready(function(){

        $("#add-teachers").click(function () {
            $("#teachers-lists").hide();
            $("#teachers-forms").fadeIn();
        });

        $("#save-teachers").click(function () {
            $("#teachers-forms").hide();
            $("#teachers-lists").fadeIn();
        });

        $( "#teachers-forms" ).validate({
            ignore: 'hidden',
            rules: {
                name: "required",
                profession: "required",
                teacher_type: "required",
                extended_date: "required",
                validity_duration: "required",
            },
            messages: {
                name: "Please enter it."
                profession: "Please enter it."
                teacher_type: "Please select it."
                extended_date: "Please enter it."
                validity_duration: "Please select it."
            }
        });
    });
</script>

这是html表单代码

<form id="teachers-forms" method="post">
    <div class="row">
        <div class="col-md-6">
            <div class="form-group">

Answer 1

您必须防止默认的浏览器行为（在服务器端提交），方法是单击“提交”按钮，例如

$("#save-teachers").click(function (event) {
    event.preventDefault();
    $("#teachers-forms").hide();
    $("#teachers-lists").fadeIn();
});

或

$("#teachers-forms").submit(function (event) {
    event.preventDefault();
});

您可以查看Prevent Default on Form Submit jQuery和event.preventDefault() vs. return false了解更多详细信息。

Answer 2

您在验证中使用了错误的ID。

您的表单是：teachers-forms 然后您将验证应用于：$( "#communicated-teachers-forms" )

只需写：

 $( "#teachers-forms" ).validate.validate({
            ignore: 'hidden',
            rules: {
                name: "required",
                profession: "required",
                teacher_type: "required",
                extended_date: "required",
                validity_duration: "required",
            },
            messages: {
                name: "Please enter it."
                profession: "Please enter it."
                teacher_type: "Please select it."
                extended_date: "Please enter it."
                validity_duration: "Please select it."
            }
        });
