bad87fee1348bd9aed508826 Clone an Element Using jQuery 6 使用jQuery克隆元素

Description

除了移动元素,您还可以将它们从一个地方复制到另一个地方。 jQuery有一个名为clone()的函数,它可以复制一个元素。例如,如果我们想将target2从我们的left-well复制到right-well ,我们将使用: $("#target2").clone().appendTo("#right-well");您是否注意到这涉及将两个jQuery函数粘在一起这称为function chaining 它是使用jQuery完成任务的便捷方式。克隆你的target5元素并将其附加到你的left-well

Instructions

Tests

tests:
  - text: 你的<code>target5</code>元素应该在你的<code>right-well</code> 。
    testString: 'assert($("#right-well").children("#target5").length > 0, "Your <code>target5</code> element should be inside your <code>right-well</code>.");'
  - text: 您的<code>target5</code>元素的副本也应该在您的<code>left-well</code> 。
    testString: 'assert($("#left-well").children("#target5").length > 0, "A copy of your <code>target5</code> element should also be inside your <code>left-well</code>.");'
  - text: 只使用jQuery来移动这些元素。
    testString: 'assert(!code.match(/class.*animated/g), "Only use jQuery to move these elements.");'
