bad87fee1348bd9aed308826	Target the Parent of an Element Using jQuery	6		使用jQuery定位元素的父级

Description

每个HTML元素都有一个parent元素，它从中inherits属性。例如，您的jQuery Playground h3元素具有<div class="container-fluid">的父元素，它本身具有父body 。 jQuery有一个名为parent()的函数，允许您访问您选择的任何元素的父级。下面是一个如何使用parent()函数的例子，如果你想给left-well元素的父元素一个蓝色的背景颜色： $("#left-well").parent().css("background-color", "blue")为#target1元素的父级#target1背景颜色为红色。

Instructions

Tests

tests:
  - text: 你的<code>left-well</code>元素应该有红色背景。
    testString: assert($("#left-well").css("background-color") === 'red' || $("#left-well").css("background-color") === 'rgb(255, 0, 0)' || $("#left-well").css("background-color").toLowerCase() === '#ff0000' || $("#left-well").css("background-color").toLowerCase() === '#f00');
  - text: 您应该使用<code>.parent()</code>函数来修改此元素。
    testString: assert(code.match(/\.parent\s*\(\s*\)\s*\.css/g));
  - text: '应该在<code>#target1</code>元素上调用<code>.parent()</code>方法。'
    testString: assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?#target1\s*?(?:'|")\s*?\)\s*?\.parent/gi));
  - text: 只使用jQuery将这些类添加到元素中。
    testString: assert(code.match(/<div class="well" id="left-well">/g));
