Here are some examples of what content scripts can do:
·Find unlinked URLs in web pages and convert them into hyperlinks
·Increase the font size to make text more legible
·Find and process microformat data in the DOM
However, content scripts have some limitations. They cannot:
·Use chrome.* APIs (except for parts of chrome.extension)
·Use variables or functions defined by their extension's pages
·Use variables or functions defined by web pages or by other content scripts
·Make cross-site XMLHttpRequests
在刚开始制作Chrome Extensions时，老没记住，就做了个测试：
manifest.json：
{
"name": "My First Extension",
"version": "1.0",
"description": "The first extension that I made.",
"content_scripts": [
{
"matches": ["http://localhost/Index.htm"],
"js": ["CallFun.js"]
}
]
}CallFun.js：
try{ShowTime();}catch(e){alert("error: " + e.message);}Index.htm：
