我想增加功能是: 增加一个全选按钮

将左侧表单所有内容 输入到右侧, 过滤重复的

我改了改怎么改都有问题,请高手帮帮忙,谢谢了

[灬上海爽爷]

挺简单吧。。我稍微改了下。
asp文件这边改一下
<td width="74" align="center"><input name="ti" type="button" onClick="tijiao()" value="选取>>"><input name="tiall" type="button" onclick="tijiaoall()" value="全部选取" /></td>

js文件加一个tijiaoall()函数
function tijiaoall(){
yuanshi=document.myform.yuanshi;
jieshou=document.myform.jieshou;
jieshou.length=0;
for (var i=0;i<yuanshi.length;i++)
{
jieshou.length++;
jieshou.options[i].text=yuanshi[i].value;
}
}

就加在tijiao()后面好了。

[灬上海爽爷]

先清空右边表里的值。然后把循环左边的表。每循环一次，都把当前的OPTION添加到右边的表里。这样就不用判断了。因为左边的表里是不会有重复记录的吧？

[灬上海爽爷]

对了。全部删除没写。那样更简单了。
直接document.myform.jieshou.length=0;
就好了。

[jtnwl]

谢谢,tcwsyt 十分感谢您

左侧表使用AJAX 可以按部门过滤

现在 全部选取 后, 会把右侧表清空后再添加

怎么做能保留右侧表中的内容呢? 如果有重复的自动过滤就更好了 哈哈 再次谢谢您

[jtnwl]

我原代码下载地址是： http://u.115.com/file/f88151aa0b

[jtnwl]

没人能帮帮我吗?

[灬上海爽爷]

你没有按我的试过么？你更换部门后并不会清空右边的表啊，只有当你点击全部选取后才会。
这是我能想到最简便跟最容易懂的方法了。或者你想要什么效果？我觉得你说的要求现在都有了。

[jtnwl]

谢谢您,还是有点小问题 我自己试试解决吧 再次感谢信您
