JS gets the absolute path implementation code, and js gets the absolute path

In projects, we often need to obtain the absolute path of the project, so that we can easily upload and download files. JS provides us with a method, although it is worth a while. The Code is as follows:

Function getRealPath () {// obtain the current URL, for example, http: // localhost: 8083/myproj/view/my. jsp var curwwwpathpattern contains invalid Doc ument. location. href; // The directory after obtaining the host address, for example, myproj/view/my. jsp var pathname=w.doc ument. location. pathname; var pos = curWwwPath. indexOf (pathName); // obtain the host address, for example, http: // localhost: 8083 var localhostPaht = curWwwPath. substring (0, pos); // obtain the project name with "/", for example,/myproj var projectName = pathName. substring (0, pathName. substr (1 ). indexOf ('/') + 1); // get http: // localhost: 8083/myproj var realPath = localhostPaht + projectName; alert (realPath );}
