JavaScript獲取路徑的方法有很多，網(wǎng)上也可以搜索的到，下面本例也要為大家講解下，有源碼及結果截圖

1、設計源碼

復制代碼代碼如下:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>

<title>JavaScript獲取路徑</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()
{
//獲取當前網(wǎng)址
var curNetAddr = window.document.location.href;
alert("獲取當前網(wǎng)址:" + curNetAddr);

//獲取主機地址之后的目錄
var hostPath = window.document.location.pathname;
alert("獲取主機地址之后的目錄：" + hostPath);

//返回某個指定的字符串值在字符串中首次出現(xiàn)的位置
var count = curNetAddr.indexOf(hostPath);
alert("返回某個指定的字符串值在字符串中首次出現(xiàn)的位置：" + count);

//獲取主機地址
var hostAddr = curNetAddr.substring(0,count);
alert("獲取主機地址：" + hostAddr);

//獲取帶“/”的項目名
var projectName = hostPath.substring(0,hostPath.substr(1).indexOf('http://www.survivalescaperooms.com/')+1);
alert("獲取帶“/”的項目名：" + projectName);

//獲取項目路徑
var path = hostAddr + projectName;
alert("獲取項目路徑：" + path);
}
</script>

</head>

<body>
<div>
<input type="button" value="獲取路徑"/>
</div>
</body>
</html>
