html页面中怎么获取项目根目录和引入js和css?
<script src="../../../../../scripts/***.js></script>
除了如上边那种用多个父路径外还有没有别的方法直接获取项目跟路径。获取项目根目录
在jsp里去<%=request.getContextPath()%>这就是项目的根路径了,是到项目这层的。
js的引入方法如下:
<script src="<%=request.getContextPath() %> /home/test.js"></script>
css的引入方法:
<link href="<%=request.getContextPath() %>/css/one.css" rel="stylesheet" type="text/css">。/js获取项目根路径,如: http://localhost:8080/ems
getRootPath:function () {
//获取当前网址,如: http://localhost:8080/ems/Pages/Basic/Person.jsp
var curWwwPath = window.document.location.href;
//获取主机地址之后的目录,如: /ems/Pages/Basic/Person.jsp
var pathName = window.document.location.pathname;
var pos = curWwwPath.indexOf(pathName);
//获取主机地址,如: http://localhost:8080
var localhostPath = curWwwPath.substring(0, pos);
//获取带"/"的项目名,如:/ems
var projectName = pathName.substring(0, pathName.substr(1).indexOf('/') + 1);
return(localhostPath + projectName);
