javascript关闭当前页面并刷新前一页面

使用了如下代码，在Ajax执行返回成功后，提示信息，关闭当前页面并刷新前一页面（即打开当前页面的页面）。
但是目前能够显示提示信息和关闭当前页面，但是无法刷新前一页面，求问题解决方法，谢谢！$.ajax({
                                type: "POST",
                                url: "<{spUrl c='sentences' a='modifyAjax'}>",
                                data: postdata,
                                success: function(msg){       
                                        //alert(msg);
                                        if(msg == 'true'){
                                                window.alert("修改成功！");
  window.self.close();
  window.opener.location="javascript:reloadPage();";
                                        }
                                },
                                complete: function(xhr,status){ 
                                }
                        });
