父页面中

 window.autosend = function (obj) {
      //获取对应行的数据，
      var datafather = obj.data;
      // console.log(data)
      layer.open({

        area: ['600px', '400px'],
        content: 'autosend',
        success: function(layero, index){
          var body = layui.layer.getChildFrame('body', index);
          if(datafather){
            // 取到弹出层里的元素，并把编辑的内容放进去
            body.find(".id").val(datafather.id);  //将选中的数据的id传到编辑页面的隐藏域，便于根据ID修改数据
            body.find(".email").val(datafather.email);  //邮箱

子页面中

<form class="layui-form" style="width: 100%;margin-top: 55px;" lay-filter="autosendTable" action="">
    <div class="layui-form-item">
        <div class="layui-inline">

            <div class="layui-input-inline layui-input-wrap">
                <!-- 使用隐藏域用于保存编辑项的ID值，便于提交修改 -->

测试是否获取到数据

<script>
  layui.use(['form', 'jquery'], function () {
    var form = layui.form
    var $ = layui.jquery
    var layer = layui.layer;    

    form.on('submit(autosend)', function (data) {
      var roleIds = ''
      $('input[type=checkbox]:checked').each(function () {
        roleIds += $(this).val() + ','
      })
      roleIds = roleIds.substr(0, roleIds.length - 1)
      data.field.roleIds = roleIds
      console.log(data.field)
   )}
  }
