## Description
<section id='description'>

    testString: assert(code.match(/\{\s*\}\);/g));
  - text: 保持<code>script</code>标签不变。
    testString: assert(code.match(/<script>/g));
  - text: 保持<code>$&#40document&#41.ready&#40function&#40&#41 {</code>在<code>script</code>标签的开头不变。
    testString: assert(code.match(/\$\(document\)\.ready\(function\(\)\s?\{/g));
  - text: "保持 'document ready function' 用<code>&#125;&#41;</code>闭合。"
    testString: assert(code.match(/.*\s*\}\);/g));
  - text: 保持<code>script</code>标签闭合。
