要求：
选择出租，只能选择 "业主出租 "和 "业主出售 "，
选择求租，只能选择“业主出租”和“承租后合租” ，其它的不能选，
[解决办法]
很简单的
[解决办法]
1。 "业主出租 "和 "业主出售 "，“承租后合租”的name最好不相同，这样就可以根据name确定将哪个变为不可用了
2。或者用id属性来唯一标识每一个radio，然后将你想不选的赋值成不可编辑enable＝false（单词我拼不好，E文不过关，见谅）
3。或者用document.getElementsByName( 'listerStatus ')获得所有同名radio的数组，然后把你不想选的赋值false就行了，就像上面第二个方法，数组会用吧？
