js获取web项目根目录

function getRootPath() {
    //获取当前网址,如: http://localhost:8088/test/test.jsp
    var curPath = window.document.location.href;
    //获取主机地址之后的目录,如: test/test.jsp
    var pathName = window.document.location.pathname;
    var pos = curPath.indexOf(pathName);
    //获取主机地址,如: http://localhost:8088
    var localhostPath = curPath.substring(0, pos);
    //获取带"/"的项目名,如:/test
    var projectName = pathName.substring(0, pathName.substr(1).indexOf('/') + 1);
    return (localhostPath + projectName);//发布前用此
}

使用 url: getRootPath() + "test/test.jsp"
