Grails, JavaScript gets the current deployment project path

JavaScript gets the current deployment project path:

The main use of the Location object, which contains information about the current URL, is a part of the Window object that can be accessed through the Window.location property.

Method One (window.document.location.href/window.document.location.pathname)------------ transferred from the network

functionGetrootpath_web () {//get the current URL, such as: http://localhost:8083/uimcardprj/share/meun.jsp            varCurwwwpath =Window.document.location.href; //gets the directory after the host address, such as: uimcardprj/share/meun.jsp            varPathName =Window.document.location.pathname; varpos =Curwwwpath.indexof (pathName); //get host address, such as: http://localhost:8083            varLocalhostpaht = curwwwpath.substring (0, POS); //get the project name with "/", such as:/uimcardprj            varProjectName = pathname.substring (0, Pathname.substr (1). IndexOf ('/') + 1); return(Localhostpaht +projectName); }

Method Two (Window.location.pathname/window.location.protocol/window.location.host)

function getrootpath_dc () {            var pathName = window.location.pathname.substring (1);             var webName = PathName = = "? ": pathname.substring (0, Pathname.indexof ('/'));             if (WebName = = "")                {return Window.location.protocol + '//' + window.location.host            ;}             Else {                return Window.location.protocol + '//' + Window.location.host + '/' + webName;            }        }

Note:

1, the document is implied by an object, window is the object of a Windows, a window can have more than one document object.
So there is only one window.location.href under a window, but there may be multiple document.url, document.location.href------------ transferred from the network

2, Window.location.href and document.location.href can be assigned value, and then jump to other pages, Document.url can only read cannot write------------ transferred from the network

3. Location Object Details Reference W3school http://www.w3school.com.cn/jsref/dom_obj_location.asp
