bad87fee1348bd9aed608826	6	18340	使用 jQuery 的 appendTo 方法移动元素

Description

现在我们学习把标签从一个div移动到另一个div。 jQuery 有一个appendTo()方法，可以选取 HTML 标签并将其添加到另一个标签里面。例如，如果要把target4从右框移到左框，可以设置如下： $("#target4").appendTo("#left-well"); 请把target2标签从left-well移动到right-well。

Instructions

Tests

tests:
  - text: <code>target2</code>标签应该不在<code>left-well</code>内。
    testString: assert($("#left-well").children("#target2").length === 0);
  - text: <code>target2</code>标签应该在<code>right-well</code>内。
    testString: assert($("#right-well").children("#target2").length > 0);
  - text: 仅用 jQuery 移动这些标签。
    testString: assert(!code.match(/class.*animated/g));

Challenge Seed

<script>
  $(document).ready(function() {
    $("#target1").css("color", "red");
    $("#target1").prop("disabled", true);
    $("#target4").remove();

  });
</script>

<!-- 请修改本行以上的代码 -->

<div class="container-fluid">
  <h3 class="text-primary text-center">jQuery Playground</h3>
  <div class="row">
    <div class="col-xs-6">
      <h4>#left-well</h4>
      <div class="well" id="left-well">
        <button class="btn btn-default target" id="target1">#target1</button>
        <button class="btn btn-default target" id="target2">#target2</button>
        <button class="btn btn-default target" id="target3">#target3</button>
      </div>
    </div>
    <div class="col-xs-6">
      <h4>#right-well</h4>
      <div class="well" id="right-well">
        <button class="btn btn-default target" id="target4">#target4</button>
        <button class="btn btn-default target" id="target5">#target5</button>
        <button class="btn btn-default target" id="target6">#target6</button>
      </div>
    </div>
