解决方案 »

  1.   

    <input type="radio" value="1" id="chkLock1" onclick="lock(this)" name="chkLock" /><label for="chkLock">启用DHCP</label>
    <INPUT TYPE="radio" NAME="chkLock" id="chkLock2" >不启用DHCP就这个改下看看..
      

  2.   

    不是<input type="radio" value="1" id="chkLock" onclick="lock(this)" name="chkLock" /> <label for="chkLock">启用DHCP </label> 
    <INPUT TYPE="radio" NAME="chkLock" id="chkLock2" >不启用DHCP 
    不论单选还是多选，都在 chkLock是否 Checked... 代码貌似不用改。

    写一个demo给你看看
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
    <head>
    <title>系统</title>
    <script>
    function change(flag){
    var obj = document.getElementById("con");
    var inputs = obj.getElementsByTagName("input");
    if(flag){
    for(var i=0;i<inputs.length;i++){
    inputs[i].disabled = 'disabled';
    }
    }else{
    for(var i=0;i<inputs.length;i++){
    inputs[i].disabled = '';
    }
    }
    }
    </script>
    </head><body>
    <div>
    <input type="radio" name="dhcp" onClick="change(true)">启用DHCP<input type="radio" name="dhcp" onclick="change(false)" checked>禁用DHCP
    </div>
    <div id="con">
    IP地址：<input type="text" name="ip"/>
    子网掩码：<input name="netmask" type="text"  id="netmask"/>
    默认网关：<input name="gateway" type="text"  id="gateway"/>
    </div>
    </body>
    </html>

    不对呀 把1楼和4楼的代码都写上去 就成了 当启用dhcp和不启用的时候都不能改上面的IP表单框了是为什么呀？请高手再改下好吗
