jquery获取radio单选按钮的值
单选组radio:
$("input[@type=radio][@
checked]").val();
单选组radio:
$("input[@type=radio]").attr("checked",'2'); //设置value=2的项目为当前选中项
获取一组radio被选中项的值:
var item = $('input[@name=items][@checked]').val();
radio单选组的第二个元素为当前选中值:
$('input[@name=items]').get(1).checked = true
单选组 radio:
$("input[@type=radio]").attr("checked",'2'); //设置value=2的项目为当前选中项
jquery老版本:
var_name = $("input[@name='radio_name']:checked").val();
jquery 1.3以后的版本:
var_name = $("input[name='radio_name']:checked").val();
例子,jquery获取radio值:
