RadioButton获取值和赋值，使用js

<input type="radio" name="RadioName1"  value="3" /><span style="vertical-align:middle; font-size: small" >单选按钮1</span>
<input type="radio" name="RadioName1"  value="2" /><span style="vertical-align:middle; font-size: small" >单选按钮2</span>
<input type="radio" name="RadioName1"  value="0" /><span style="vertical-align:middle; font-size: small" >单选按钮3</span>

//赋值给组件
var radioValue = x;
if(radioValue == 3){
	$("input[name='RadioName1'][value=3]").attr("checked",true);
} else if(radioValue == 2){
	$("input[name='RadioName1'][value=2]").attr("checked",true);
} else if(radioValue == 0){
	$("input[name='RadioName1'][value=0]").attr("checked",true);
}
 
//获取组件的值
var value = $("input[name='RadioName1']:checked").val();
