jQuery和单选按钮组 [英] jQuery and radio button groups

问题描述

在jQuery中，我想选择未选中任何按钮的所有单选按钮组.

In jQuery, I'd like to select all groups of radio buttons where there are no buttons checked.

或者，有没有一种方法可以选择所有单选按钮组并遍历这些组?

Or, is there a way in which I can select all radio button groups and iterate through the groups?

我正在向页面动态添加N个单选按钮组，并且事先不会知道单选按钮组的名称.

I'm dynamically adding N radio button groups to a page and will not know, before hand, what the names of the radio button groups will be.

推荐答案

查找所有广播组:

var radio_groups = {}
$(":radio").each(function(){
    radio_groups[this.name] = true;
})

查找哪个广播组已选中单选框，而没有:

to find which radio group has checked radio boxes and which hasn't:

for(group in radio_groups){
    if_checked = !!$(":radio[name='"+group+"']:checked").length
    alert(group+(if_checked?' has checked radios':' does not have checked radios'))
}
