//js获取项目根路径，如： http://localhost:8080/SLSaleSystem
function getRootPath(){
    //获取当前网址，如： http://localhost:8080/SLSaleSystem/pages/index.jsp
    var curWwwPath=window.document.location.href;
    //获取主机地址之后的目录，如： SLSaleSystem/pages/index.jsp
    var pathName=window.document.location.pathname;
    var pos=curWwwPath.indexOf(pathName);
    //获取主机地址，如： http://localhost:8080
    var localhostPaht=curWwwPath.substring(0,pos);
    //获取带"/"的项目名，如：/SLSaleSystem
    var projectName=pathName.substring(0,pathName.substr(1).indexOf('/')+1);
    return(localhostPaht+projectName);
}
