浅谈监听单选框radio改变事件(和layui中单选按钮改变事件)

<input type="radio" name="sex" checked="checked" value="1">男<input type="radio" name="sex" value="2">女

$(document).ready(function() {  $('input[type=radio][name=sex]').change(function() {  if (this.value == '1') {    alert("这是个男孩");   } else if (this.value == '2') {    alert("这是个女孩");   }  }); });

layui.use(['form', 'element', 'laydate'], function(){ var jQuery = layui.jquery ,layer = layui.layer ,form = layui.form() ,element = layui.element(); form.on("radio(sex)", function (data) {  var sex = data.value;  if (this.value == '1') {    alert("这是个男孩");   } else if (this.value == '2') {    alert("这是个女孩");   }  });});
