//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)
}
如下:先获取系统路径:Stirng path = request.getContextPath()
然后再调用的时候写:<script type="text/javascript" src="<%=path%>/js/demo.js"></script>
希望可帮助到你,望采纳!
