Get Value of Radio button group
提问by Parampal Pooni
I'm trying to get the value of two radio button groups using the jQuery syntax as given below. When the code below is run I get the value selected from the first radio button group twice instead of getting the value of each individual group.
我正在尝试使用下面给出的 jQuery 语法获取两个单选按钮组的值。当下面的代码运行时，我从第一个单选按钮组中选择了两次，而不是获取每个单独组的值。
Am I doing something obviously wrong here? Thanks for any help :)
我在这里做错了什么吗？谢谢你的帮助 ：）
<a href='#' id='check_var'>Check values</a><br/><br/>
<script>
$('a#check_var').click(function() {
alert($("input:radio['name=r']:checked").val()+ ' ' +
$("input:radio['name=s']:checked").val());
});
</script>
Group 1<br/>
<input type="radio" name="r" value="radio1"/> radio1
<input type="radio" name="r" value="radio2"/> radio2
<br/><br/>
Group 2<br/>
<input type="radio" name="s" value="radio3"/> radio3
<input type="radio" name="s" value="radio4"/> radio4

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:
你的报价只需要围绕价值的部分属性等于选择，[attr='val']像这样：
$('a#check_var').click(function() {
alert($("input:radio[name='r']:checked").val()+ ' '+
$("input:radio[name='s']:checked").val());
});?
