JS 获取网站根目录 域名+站名

//获取根路径
function getBasePath() {
    var curWwwPath = window.document.location.href;
    var pathName = window.document.location.pathname;
    var pos = curWwwPath.indexOf(pathName);
    var localhostPaht = curWwwPath.substring(0, pos);
    var projectName = pathName.substring(0, pathName.substr(1).indexOf("/") + 1);
    return (localhostPaht + projectName);
}

注：需要在VS或者 IIS中测试
