This article mainly introduces the implementation code for JS to obtain the absolute path. For more information, see the absolute path of the project in the project, 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 );}
