js 中获取上下文路径

//js获取项目根路径，如： http://localhost:8083/uimcardprj function getRootPath(){
    //获取当前网址，如： http://localhost:8083/uimcardprj/share/meun.jsp     var curWwwPath=window.document.location.href;
   
    //获取主机地址之后的目录，如： uimcardprj/share/meun.jsp
    var pathName=window.document.location.pathname;
    var pos=curWwwPath.indexOf(pathName);
    
    //获取主机地址，如： http://localhost:8083     var localhostPaht=curWwwPath.substring(0,pos);
    
    //获取带"/"的项目名，如：/uimcardprj
    var projectName=pathName.substring(0,pathName.substr(1).indexOf('/')+1);
    
   return(localhostPaht+projectName);
}

微商城中使用到了：single.js

var curWwwPath=window.document.location.href;
var pathName=window.document.location.pathname;
var pos=curWwwPath.indexOf(pathName);
//获取主机地址，如： http://localhost:7070 var localhostPaht=curWwwPath.substring(0,pos);
//alert(localhostPaht);
this.uploadUrl = localhostPaht +"/shop/weixin/ajaxUploadPic";

============================华丽的分隔符============================

java中获取

Map<String, Object> map = new HashMap<String, Object>();
map.put("url", request.getContextPath() +"/weixin/business_single?sessionId="+sessionId);

最终的结果：http:localhost:8080/shop/weixin/business_single?sessionId=1234
