JavaScript实现的搜索及高亮显示功能示例

<div class="contracts-header">名称: <input type="text" value="" id="search_contract_name"></div>
<div class="contracts-header">代码: <input type="text" value="" id="search_contract_code" placeholder="不区分大小写"></div>
<div class="contracts-header"><button onclick="search()">查找</button></div>
<div id="contracts-list">
  <ul>
  <li><input type="checkbox" name="contract[]" value="code|name" /><span>name(code)</span></li>
  <li><input type="checkbox" name="contract[]" value="code|name" /><span>name(code)</span></li>
  </ul>
</div>
