Js:返回上一页

一、返回上一页

  document.referrer

        function backPage() {
              //window.history.back(-1) //返回上一页
            if (document.referrer != '') {
                window.location.href = (document.referrer)
            }else
             {
              window.location.href = "default.aspx";
             }
        }

二、刷新本页

1    history.go(0)
2    location.reload()
3    location=location
4    location.assign(location)
5    document.execCommand('Refresh')
6    window.navigate(location)
7    location.replace(location)
8    document.URL=location.href
