bootstrap弹出模态框

1.引入bootstrap相关js

bootstrap.min.js
jquery-2.2.3.min.js
bootstrap.min.css

2.写模态框弹出按钮

<p>
    <a data-toggle="modal" data-target="#myModal" class="btn btn-primary btn-large">添加应用a>
p>

3.写模态框主体

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×span>button>
        <h4 class="modal-title" id="myModalLabel">Modal titleh4>
      div>
      <div class="modal-body">
        <form action="../../addApp" method="get">
            <label>Appidlabel>
            <input type="text" name = "appId"><br/>
            <label>秘钥label>
            <input type="text" name = "appSecret"><br/>
            <label>网址label>
            <input type="text" name = "url"><br/>
            <input type="submit" value="确定">
        form>
      div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Closebutton>
        
      div>
    div>
  div>

4.添加js（貌似不加也能出来）

$('#myModal').on('shown.bs.modal', function () {
  $('#myInput').focus()
}) 

5.最好感谢我的队友帮我改bug叫我模态框，例子来自官网
注意：主体最好放在最外层标签，以免互相影响
