双击select 移除某项ondblclick="this.removeChild(this.options[this.selectedIndex])"
不必在option 上定义 。代码如下:
<select style="400;height:300;" multiple="true"
ondblclick="this.removeChild(this.options[this.selectedIndex])">
<option value="aaa">aaa</option>
<option value="aaa">bbb</option>
<option value="aaa">ccc</option>
<option value="aaa">ddd</option>
<option value="aaa">eee</option>
</select>
