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。我尝试过使用<button type="submit">，<input type="button">和<input type="submit">。 Here is the live version了解更多背景信息。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">

        </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。只需让表单包裹整个模态窗口就像这样...

    <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">
                            <input type="text" class="form-control" id="inputID" placeholder="Student ID Number">
                        </div>
                     </div>

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

                    <div class="form-group">

Answer 3

删除

中的属性data-dismiss = "modal"

<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>

Answer 4

因为提交按钮位于表单元素之外。

将表单元素包装在.modal-body周围 - 这将确保所有表单字段和输入按钮都在要提交的表单中。

此外，将一些样式应用于具有0填充和0边距的表单，因为它可能会推动表单使模态看起来不整洁。

希望它有所帮助，这就是我所做的，它对我来说很好。
