checkbox的问题

[xiongbing529]

<input type=checkbox value=1 name="a1" id="a1"><input type=text name="name1" id="name1">

<input type=checkbox value=2 name="a2" id="a2"><input type=text name="name2" id="name2">

只有选择了复选框 a1，才让text name1里面能输入文字 ，否则，就不能输入


只有选择了复选框 a2，才让text name2里面能输入文字 ，否则，就不能输入

请问 ，这样的 js则么写啊

<input type=checkbox value=1 name="a1" id="a1" onclick='check(this,"name1")'> <input type=text name="name1" id="name1" disabled>

<input type=checkbox value=2 name="a2" id="a2" onclick='check(this,"name1")'> <input type=text name="name2" id="name2" disabled>


JScript code

function check(box,txt){
document.getElementById(txt).disabled=box.checked?false:true;
}

不好意思，HTML代码有个错：

<input type=checkbox value=1 name="a1" id="a1" onclick='check(this,"name1")'> <input type=text name="name1" id="name1" disabled> 

<input type=checkbox value=2 name="a2" id="a2" onclick='check(this,"name2")'> <input type=text name="name2" id="name2" disabled>

<input type=checkbox value=1 name="a1" id="a1" onclick="name1.disabled=!name1.disabled"> <input type=text name="name1" id="name1" disabled> 

<input type=checkbox value=2 name="a2" id="a2" onclick="name2.disabled=!name2.disabled"> <input type=text name="name2" id="name2" disabled> 

[mailto520]

<input type=checkbox value=1 name="a1" id="a1" onclick='check()'> <input type=text name="name1" id="name1" disabled>

function check()
{
var obj = document.getElementById("a1");
var text =document.getElementById("name1");
text.readOnly = !obj.checked ? true : false;

}
