layui 监听 select下拉选择框

layui组件，js或jq对其的监听事件会失效，需要代码才能实现：

1.html部分

<select name="category" lay-verify="required" lay-filter="cate"><option value ="分类1">分类1</option>
??????? <option value ="分类2">分类2</option></select>

2.js部分

<script src="__PUBLIC__/index/js/layui.js"></script>
<script>
layui.use(['layer', 'laydate', 'form', 'element'],function () { var layer = layui.layer, //layer初始化form = layui.form, //表单初始化element = layui.element, table = layui.table;             form.on('select(cate)', function(obj){$('.layui-form').submit(); }); 
???????})
</script>

注意select小括号里面的值对应，标签属性lay-filter的值‘cate’
