js中获取上下文路径

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”;

java中获取
Map map = new HashMap();
map.put(“url”, request.getContextPath() +”/weixin/business_single?sessionId=”+sessionId);
最终的结果：http:localhost:8080/shop/weixin/business_single?sessionId=1234
