js 延迟几秒刷新或转跳

setTimeout(function(){
    self.location='{:url('course',['pid'=>$pid,'cid'=>$cid])}';
},1000);

例子：

            //创建直播
                    $(document).on("click",".addlive",function(){
                          var arrid = $(this).attr("lay-id");
                                var strs= new Array(); //定义一数组
                                strs=arrid.split("|"); //字符分割
                                pid= strs[0];
                                cid= strs[1];
                                bid= strs[2];
                                ccid= strs[3];
                                
                                var index = layer.load(1, {
                                    shade: [0.5,'#000'] //0.1透明度的白色背景
                                });

                                $.ajax({
                                    url:'{:url('course_add')}',
                                    type:"post",
                                    data:{pid:pid,cid:cid,bid:bid,ccid:ccid,action:'addlive'},
                                    async:true,
                                    success:function(data){
                                         layer.closeAll('loading'); //关闭加载层
                                         if(data['code']==1){
                                            layer.msg(data['msg']);
                                          }else{
                                            layer.msg(data['msg']);
                                             //table.render({});//重新渲染
                                          }
                                            setTimeout(function(){
                                                self.location='{:url('course',['pid'=>$pid,'cid'=>$cid])}';
                                            },3000);
                                    },
                                    error:function(){
                                      layer.closeAll('loading'); //关闭加载层
                                      layer.msg('失败！');
                                    }
                                });
