javascript - Onclick 仅重新加载 div

Question

$(window).load(function() {      
  $("#Button").click(function() {
    alert('clicked')
    $("#div").load(" #div > *");
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>

<button id="Button" class="btn btn-warning">Refresh</button>
<div class="col-md-3" id="div">

  <div class="alert alert-warning alert-dismissible fade in" role="alert">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close">
      <span aria-hidden="true">×</span>
    </button>
    <strong>Holy guacamole!</strong>
  </div>
  <div class="alert alert-danger alert-dismissible fade in" role="alert">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close">
      <span aria-hidden="true">×</span>
    </button>
    <strong>Holy guacamole!</strong>
  </div>
  <div class="alert alert-success alert-dismissible fade in" role="alert">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close">
      <span aria-hidden="true">×</span>
    </button>
    <strong>Holy guacamole!</strong>

  </div>
</div>

这是当我单击刷新按钮时尝试重新加载 div 的代码，没有任何反应，因为我是学习者jQuery 和 JS 的我对此了解不多。

在 jQuery 版本 3 中，函数加载和事件加载的处理方式不同。

所以在你的代码中你需要编写:

$(window).on('load', function (e) {

有关详细信息，请查看jQuery 3.0 :

Removed deprecated event aliases

.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.

由于 Bootstrap v3 与 jQuery v3 不兼容(请参阅 bootstrap issues 16834 )，我在代码片段中更改为 jQuery 1.x。

我的片段:

$(window).on('load', function (e) {
  $('#MyButton').on('click', function (e) {
    alert('clicked')
    $("#div").load(" #div > *");
  });
});

<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

<button id="MyButton" class="btn btn-warning">Refresh</button>
<div class="col-md-3" id="div">

    <div class="alert alert-warning alert-dismissible fade in" role="alert">
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">×</span>
        </button>
        <strong>Holy guacamole!</strong>
    </div>
    <div class="alert alert-danger alert-dismissible fade in" role="alert">
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">×</span>
        </button>
        <strong>Holy guacamole!</strong>
    </div>
    <div class="alert alert-success alert-dismissible fade in" role="alert">
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">×</span>
        </button>
