Javascript 如何使用网站url查找文件夹

我的网站上有UpFiles文件夹

我想在下面的代码中定义struploadurl

当我在localhost上运行这个网站时，它工作得很好

但当我在不同的服务器上部署我的网站时，它将不起作用，所以我在代码中使用了“window.location.href”

  function Initialisation() {   
  // Want path same as below like url.
  //  var struploadurl = "http://localhost/MyProject/UpFiles/uploadsave.aspx";      
  // where arr[0] = http , arr[2] =Server Name and arr[3] =Projectname  

    var url = window.location.href;
    var arr = url.split("/");         
    var result = arr[0] + "//" + arr[2] + "//" + arr[3];
    var strPath = result + "/UpFiles/uploadsave.aspx";
    alert(strPath);    

}

问题是，当我使用这个端口网站，所以它不会工作。我想要一个通用的解决方案，这样当我的网站没有端口或也使用端口部署时，我就可以得到struploadurl

例如，当我使用部署我的站点时“htp://Servrname/MyProject“那么上面的代码就可以工作了

当我使用“”部署我的站点时htps://ehost.test.com:446/“那么上述代码将无法工作。

使用windows.location对象。它具有标识主机和端口所需的所有属性，而不是尝试手动解析url字符串

host : localhost:800"   
hostname : "localhost"  
href : "http://localhost:800/test/"
pathname : "/test/"
port :"800"
protocol : "http:"  
search : ""

试试这个：

function Initialisation() {   
  // Want path same as below like url.
  //  var struploadurl = "http://localhost/MyProject/UpFiles/uploadsave.aspx";      
  // where arr[0] = http , arr[2] =Server Name and arr[3] =Projectname  

    var url = window.location.href;

    var strPath = "/UpFiles/uploadsave.aspx";
    var host = location.protocol+'//'+location.hostname+(location.port ? ':'+location.port: '');;
    var relativePath = url.substr(host.length+1,url.length - host.length-1);
    var rootFolder = relativePath.substr(0,relativePath.indexOf("/"));
    result = host + "/" + rootFolder + strPath;

    alert(rootFolder);    
    alert(relativePath);    
    alert(result);    

}

function Initialisation() {   
  // Want path same as below like url.
  //  var struploadurl = "http://localhost/MyProject/UpFiles/uploadsave.aspx";      
  // where arr[0] = http , arr[2] =Server Name and arr[3] =Projectname  

    var url = window.location.href;

    var strPath = "/UpFiles/uploadsave.aspx";
    var host = location.protocol+'//'+location.hostname+(location.port ? ':'+location.port: '');;
    var relativePath = url.substr(host.length+1,url.length - host.length-1);
    var rootFolder = relativePath.substr(0,relativePath.indexOf("/"));
    result = host + "/" + rootFolder + strPath;

    alert(rootFolder);    
    alert(relativePath);    
    alert(result);    

}
