indexOf()  方法可返回某个指定的字符串值在字符串中首次出现的位置

//js获取项目根路径,如: http://localhost:8083/uimcardprjfunction 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 localhostPath=curWwwPath.substring(0,pos);        //获取带"/"的项目名,如:/uimcardprj    var projectName=pathName.substring(0,pathName.substr(1).indexOf('/')+1);       return(localhostPath+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:7070var localhostPath=curWwwPath.substring(0,pos);//alert(localhostPaht);this.uploadUrl = localhostPath +"/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
