|  | ## Description
 | |||
|  | <section id="description"> JavaScript允许使用单个(“)和双(”“)引号来声明一个字符串。决定使用哪一个通常归结为个人偏好,但有一些例外。当字符串有收缩或另一个时,有两个选择很好引号中的文本片段。请注意,不要过早关闭字符串,这会导致语法错误。以下是混合引号的一些示例: <blockquote> //这些是正确的: <br> const grouchoContraction =“我度过了一个美好的夜晚,但事实并非如此。”; <br> const quoteInString =“Groucho Marx曾经说过'引用我的话说我被误引了'。”; <br> //这是不正确的: <br> const uhOhGroucho ='我度过了一个美妙的夜晚,但这不是它。'; </blockquote>当然,只使用一种报价样式是可以的。您可以使用反斜杠(\)转义字符来转义字符串中的引号: <blockquote> //正确使用相同的引号: <br> const allSameQuotes ='我度过了一个非常精彩的夜晚,但这不是它。'; </blockquote></section> | |||

|  |     testString: 'assert(code.match(/<a href=\s*?("|\\")#Home\1\s*?>/g), "Your code should fix the quotes around the <code>href</code> value "#Home" by either changing or escaping them.");' | |||
|  |   - text: 您的代码应该在整个字符串周围保留双引号。 | |||
|  |     testString: 'assert(code.match(/"<p>.*?<\/p>";/g), "Your code should keep the double quotes around the entire string.");' | |||
