jsp在js里获取项目名

function getRootPath() {
    var curWwwPath = window.document.location.href;
    var pathName = window.document.location.pathname;
    var pos = curWwwPath.indexOf(pathName);
    var localhostPath = curWwwPath.substring(0, pos);
    //获取带"/"的项目名，如：/hotel

    var projectName = pathName.substring(0, pathName.substr(1).indexOf(‘/‘) + 1);
    return projectName;

}
