JQuery搜索select里面的值

<div class="search">
<input type="text" id="Jmytext" value=""/>
</div>
 <select id="fb_list" multiple="multiple" class="search_locate" name="baseos">
 <option value="aaaabbbbbb">aaaabbbbbb</option>
<option value="ccccccccccddddddd">ccccccccccddddddd</option>
 <option value="eeeeeeeeeefffffffffff">eeeeeeeeeefffffffffff</option>
 <option value="pam-devel-0.99.6.2-6.el5.x86_04">pam-devel-0.99.6.2-6.el5.x86_04</option>
  <option value="pam-devel-0.99.6.2-6.el5.x86_05">pam-devel-0.99.6.2-6.el5.x86_05</option>
 <option value="pam-devel-0.99.6.2-6.el5.x86_06">pam-devel-0.99.6.2-6.el5.x86_06</option>
 </select>

实现的原理

1. 定义全局数组存放最初的数据

2. 触发onchange事件如果有发生就调用
