The IE plug-in developed using js can execute js code in the currently browsed page, and on this basis, any function that the user can think of can be realized.
You can do some common processing for unused websites (such as extracting certain types of information), or you can do special processing for specific websites (such as buying train tickets).
Implementing this plug-in method is relatively simple, just copy a few files and modify a registry value. Therefore, it is more suitable to quickly implement some browser or website auxiliary functions.
Implementation steps:
1. Create html files that implement specific functions
//File name: getticketslist.html
//File content:
2. Create registry file
//File name: getticketslist.reg
//File content: The CLSID in the file can be modified arbitrarily, as long as it is unique
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerExtensions{878EC0C9-AAAD-4331-9B3A-2D8BA93AEAD2}]
"CLSID"="{2FBA04EE-3024-11D2-8F1F-0000F87ABD16}"
"Default Visible"="Yes"
"Script"="c:\getticketslist.html"
"MenuText"="Handling tickets"
3. Copy the html file to the path specified in the reg file (such as c:getticketslist.html)
4. Run getticketslist.reg and modify the registry
5. Restart IE. In the menu [Tools], you can see the function "processing tickets" just added, click to execute
