LAYUI 使用formSelects时多选select下拉框，完成选择，关闭选择页后再触请求

layui.use(['form','formSelects'], function() {
        var form = layui.form;
        var formSelects = layui.formSelects;
        formSelects.on('select1', function(id, vals, val, isAdd, isDisabled){
            //id:           点击select的id
            //vals:         当前select已选中的值
            //val:          当前select点击的值
            //isAdd:        当前操作选中or取消
            //isDisabled:   当前选项是否是disabled
            $('#deviceType').val(formSelects.value('select1', 'val'));
            console.log("here.........");
        }, true);
        //监听下拉框的关闭
        formSelects.closed('select1', function(id){
            console.log('合上了');
        });
    });
