如何使用jQuery获得价值?
我可以像这样得到所有的结果:
$(form:radio)
我知道哪一个被选中?

获取选定的值 radioName
id为 myForm
的表单项:
$('input [name = radioName]:checked','#myForm')。val()
$
$('#myForm输入')。on('change',function(){alert($('input [name = radioName]:checked','#myForm').val());});
< script src =https://ajax.googleapis.com/ajax/libs /jquery/2.1.1/jque ry.min.js>< / script>< form id =myForm> < input type =radioname =radioNamevalue =1/> 1< br /> < input type =radioname =radioNamevalue =2/> 2< br /> < input type =radioname =radioNamevalue =3/> 3< br />< / form>
I have two radio buttons and want to post the value of the selected one.How can I get the value with jQuery?
I can get all of them like this:
$("form :radio")
How do I know which one is selected?
解决方案
To get the value of the selected radioName
item of a form with id myForm
:
$('input[name=radioName]:checked', '#myForm').val()
Here's an example:
$('#myForm input').on('change', function() {
alert($('input[name=radioName]:checked', '#myForm').val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm">
<input type="radio" name="radioName" value="1" /> 1 <br />
<input type="radio" name="radioName" value="2" /> 2 <br />
<input type="radio" name="radioName" value="3" /> 3 <br />
