This article will explain in detail what is the use of NPAPI in TE. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

NPAPI, which refers to Netscape plug-in Application programming Interface (Netscape Plugin Application Programming Interface), is a calling channel through which external programs act as plug-ins and browsers to display web pages together. A plug-in is equivalent to an application running on a web page. For example, if you want to play music on a web page and use tags on a web page, the browser will automatically call Windows Media Player to run, such as pdf and so on. Also, it can be used to detect and launch client applications in browsers.

TE supports NPAPI after version 6.6, but for chrome v42 or above, the NPAPI plug-in is turned off by default, and Firefox 52 stops supporting all NPAPI plug-ins, so the TE secondary development of NPAPI is basically not used.

The official provides a simple web development based on NPAPI, which can also be supported in the lower versions of chrome and firefox. If you are interested, you can try it. Here is the detailed code:

Sample

Function LoadFly () {

Try {

Var sg = CreateSGObj ()

Sg.open ("fly address")

}

Catch (e) {

Alert (e)

}

}

/ / create an object for sgworld

Function CreateSGObj () {

Var obj = document.getElementById ("sgworld")

If (obj = = null) {

Obj = document.createElement ('object')

Obj.setAttribute ("name", "sgworld")

Obj.setAttribute ("id", "sgworld")

Obj.setAttribute ("type", "application/x-skyline")

Obj.setAttribute ("clsid", "{3A4F9199 65a8-11d5-85c1-0001023952c1}")

Document.body.appendChild (obj)

}

Return obj

}
