Js calls local programs and js calls

Js calls local programs and js calls

A few days ago, when I was working on a project, I used js to call a local program and found a lot of information. One was to write the registry, and the other was to write a browser plug-in. Relatively speaking, it is easier to write a registry because the requirement is tight. The following is my summary. I hope it will be helpful to you. I forgot where to find it. I would be very grateful if I have been tired of seeing it.

Step 1:

Write to registry, registry example

Windows Registry Editor Version 5.00  [HKEY_CLASSES_ROOT\openNotepad]  @="URL:openNotepad Protocol"  "URL Protocol"=""  [HKEY_CLASSES_ROOT\openNotepad\DefaultIcon]  @="TestKZT.exe,1"  [HKEY_CLASSES_ROOT\openNotepad\shell]  [HKEY_CLASSES_ROOT\openNotepad\shell\open]  [HKEY_CLASSES_ROOT\openNotepad\shell\open\command]  @="cmd /c set m=%1 & call set m=%%m:openNotepad:=%% & call \"C:\\Windows\\TestKZT.exe\" %%m%% & exit"  

 

Save as 1.reg.

Step 2: Use a browser to call and input parameters, for example

<! Doctype html public "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
 
You can call an external program.
Other notes:
The example calls a user-defined program C: \ Windows \ TestKZT.exe. The input parameters are similar.
There is no need for a small example. If necessary, leave a mailbox.
