js如何將本地路徑轉(zhuǎn)換成http路徑？

//本地路徑轉(zhuǎn)換成URL相對(duì)路徑

private string urlconvertor(string imagesurl1)

{

string tmpRootDir = Server.MapPath(System.Web.HttpContext.Current.Request.ApplicationPath.ToString());//獲取程序根目錄

string imagesurl2 = imagesurl1.Replace(tmpRootDir, ""); //轉(zhuǎn)換成相對(duì)路徑

imagesurl2 = imagesurl2.Replace(@"\", @"/");

//imagesurl2 = imagesurl2.Replace(@"Aspx_Uc/", @"");

return imagesurl2;

}
