Bootstrap 3模式中的提交按钮不起作用

Question

我希望表单提交到同一页面,因此我将表单操作保留为黑色.我试过用<button type="submit">,<input type="button">然后<input type="submit">. 这是更多上下文的实时版本.当您单击"添加学生"时,单击"保存学生信息"按钮,它不执行任何操作,但关闭按钮可以正常工作.

这是我的模态的代码.

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
      <div class="modal-content">

          <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
          <h4 class="modal-title">Add a new student</h4>
        </div>
        <div class="modal-body">

Answer 1

您还可以使用HTML5属性:form链接表单外部的按钮(或输入)

来自w3schools网站的例子:

<form action="demo_form.asp" method="get" id="form1">
    First name: <input type="text" name="fname"><br>
    Last name: <input type="text" name="lname"><br>
</form>

<button type="submit" form="form1" value="Submit">Submit</button>

您的提交按钮位于代码之外.只需将表单包装成这样的整个模态窗口......

    <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-dialog">
         <form class="form-horizontal" role="form" method="post" action="">
          <div class="modal-content">
            <div class="modal-header">
              <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
              <h4 class="modal-title">Add a new student</h4>
            </div>
            <div class="modal-body">
                    <div class="form-group">

                        <div class="col-sm-offset-1 col-sm-10">
