推荐答案
假设你的html文件（index.html）_doesn''t_已经有了title元素 -
如果是这样，只需找到它并替换它的innerHTML
编辑：代码片段以全功能示例为例。此外，提取文件夹名称的方法已更改。 http：//localhost/enhzflep/audio/index.html的网址给出了enhzflep / audio的结果
** Obselete **
Assuming your html file (index.html) _doesn''t_ have a title element already -
If so, just locate it and replace it''s innerHTML
Code snippet suplimented with fully-functional example. Also, method of extracting folder name changed. A url of http://localhost/enhzflep/audio/index.html was giving the result of enhzflep/audio
** Obselete **
function myInit()
{
// When I open the file, it is found at:
// http://www.localhost/enhzflep/index.html
//
// Yours would be http://someDomain.com/PartYouWant/index.html
// sets locationStr = "/enhzflep/index.html"
var locationStr = window.location.pathname;
// make sure the below line reflects the actual name of the file
// sets locationStr = "enhzflep"
locationStr = locationStr.replace("/index.html", "");
locationStr = locationStr.replace("/", "");
// ** NOTE **
// I make no provisions for folders that have spaces in their names (%20 in the url)
// you'll need to unencode these yourself. There's likely a function for it urlencode
// or urlescape or something similar. Never needed it, haven't remembered it yet.
var title = document.createElement('title');
var titleText = document.createTextNode( 'Page Title = ' + locationStr );
title.appendChild( titleText );
document.head.appendChild(title);
}
使用示例：
Example of use:
<!doctype html>
<html>
<head>
<script>
window.addEventListener('load', myInit, false);
function myInit()
{
if (titleElementExists() == true)
document.getElementsByTagName('title')[0].innerText = constructPageTitleStr();
else
addPageTitle();
/*
other initialization code here.
*/
}
function titleElementExists()
{
var titleEl = document.getElementsByTagName('title');
if (titleEl.length == 0)
return false;
return true;
}
function constructPageTitleStr()
{
var locationStr = window.location.pathname;
// make sure the below line reflects the actual name of the file
// sets locationStr = "enhzflep"
locationStr = locationStr.replace("/index.html", "");
// get the position of the last / char in the string
var slashPos = locationStr.lastIndexOf("/");
// extract the string that remains after it
locationStr = locationStr.substr(slashPos+1);
return locationStr;
}
function addPageTitle()
{
var locationStr = constructPageTitleStr();
var title = document.createElement('title');
var titleText = document.createTextNode( 'Page Title = ' + locationStr );
title.appendChild( titleText );
document.head.appendChild(title);
}
</script>
<title>Original Page Title</title>
</head>
<body>
</body>
</html
>
>
<head>
<title>how it works</title>
</head>
