layui select onchange事件

1、html代码如下,不要忘记 lay-filter属性

<div class="layui-input-block">
                     <select id="brickType"  lay-filter="brickType">
                            <option value="0">--请选择型号--</option>
                            <option value="ty1">型号1</option>
                            <option value="ty2">型号2</option>
                            <option value="ty3">型号3</option>    
                       </select>
      </div>

2、javascirpt代码如下

layui.use(['form'], function() {
         form=layui.form;
form.on('select(brickType)', function(data){   
  var val=data.value;
console.info(val);

                       });

        });
