一、在当前JSP中的java代码中获取
java代码
String path = request.getContextPath();
String basePath = request.getScheme() +"://"
+ request.getServerName() +":"+ request.getServerPort()
+ path +"/";
再在JS中调用:
var basePath ='<%=basePath%>';
alert(basePath);//http://localhost:8080/
二、在跳入当前页面的action中获取根路径，放入request中，再在JS中获取
String path = request.getContextPath();
String basePath = request.getScheme() +"://"
+ request.getServerName() +":"+ request.getServerPort()
+ path +"/";
request.setAttribute("basePath", basePath);
再在JS中通过EL表达式调用:
var basePath = ${'basePath'};
alert(basePath);//http://localhost:8080/
