JavaScript获取路径
1、设计源码
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>JavaScript获取路径</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <script type="text/javascript"> function findPath() { //获取当前网址 var curNetAddr = window.document.location.href; alert("获取当前网址:" + curNetAddr); //获取主机地址之后的目录 var hostPath = window.document.location.pathname; alert("获取主机地址之后的目录:" + hostPath); //返回某个指定的字符串值在字符串中首次出现的位置 var count = curNetAddr.indexOf(hostPath); alert("返回某个指定的字符串值在字符串中首次出现的位置:" + count); //获取主机地址 var hostAddr = curNetAddr.substring(0,count); alert("获取主机地址:" + hostAddr); //获取带“/”的项目名 var projectName = hostPath.substring(0,hostPath.substr(1).indexOf('/')+1); alert("获取带“/”的项目名:" + projectName); //获取项目路径 var path = hostAddr + projectName; alert("获取项目路径:" + path); } </script> </head> <body> <div id="body_div"> <input type="button" id="btn" value="获取路径" onclick="findPath()"/> </div> </body> </html>
(1)初始化时
(2)获取当前网址
(3)获取主机地址之后的目录
(4)返回某个指定的字符串值在字符串中首次出现的位置
(5)获取主机地址
(6)获取带“/”的项目名
