JS获取几种URL地址的方法。

thisURL = document.URL;
thisHREF = document.location.href;
thisSLoc = self.location.href;
thisDLoc = document.location;
thisTLoc = top.location.href;
thisPLoc = parent.document.location;
thisTHost = top.location.hostname;
thisHost = location.hostname;
tmpHPage = thisHREF.split( "/" );
thisHPage = tmpHPage[ tmpHPage.length-1 ];
tmpUPage = thisURL.split( "/" );
thisUPage = tmpUPage[ tmpUPage.length-1 ];
