如何在特定文件的JavaScript中调用函数？

Question

var handleFileSelect;
handleFileSelect=function(e){
    n=new FileReader;
    n.onload=function(e){
    localStorage.settings = e.target.result
    },
    n.readAsText(this.files[0])
},

document.getElementById("settings_file").addEventListener("change",handleFileSelect,!1);

So, for the code above, when a User uploads a .Json file, handleFileSelect is then activated on that file.

I would like to change this so that there is no longer any need for the user to upload a file. What I mean is that I would like handleFileSelect to run on a .Json file which I have in the same folder as this .js file.

I feel like this is an easy thing to do, but I know no JavaScript whatsoever.

Thank you all for taking the time to read this.

I am coding this for a chrome extension that I am making.

Edit: How could I call the handleFileSelect function on a certain string of characters?

出于安全原因，除非用户明确为您提供文件，否则您将永远无法从用户的本地磁盘进行读取。
