如何通过按JavaScript / HTML中的按钮打开本地文件？

Question

I am very new to JavaScript and HTML. I created an example where im trying to open a local file called, "TNTplayer.html" in a JavaScript function via a button press. However, I don't know the line of code that will do that.

 function myFunction() { document.location.href=document.location.href.splitOnLast('/')[0]+"/TNTplayer.html"; } 

 <p>Click the button.</p> <button onclick="myFunction()">Try it</button> <p id="demo"></p>

Have a look at this article: http://researchhubs.com/post/computing/javascript/open-a-local-file-with-javascript.html

In general, if your HTML/JS is being served as a website, you will not have "true" access to your filesystem (which is a necessary security measure), besides the ways mentioned in the article above.

However, if you are serving it as a standalone client application, which is possible using frameworks such as Nodejs and others, there are framework specific ways of accessing the filesystem.
