If you click to upload on the page, you can click to get the files[0] in the input file;

The current requirement is to drag the image directly from the desktop to the browser. How to get the first file in files[0]?

var dropbox = document.getElementById("dropbox");

dropbox.addEventListener("dragenter", function(e){
    e.stopPropagation();
    e.preventDefault();
}, false);
            
dropbox.addEventListener("dragover", function(e){
    e.stopPropagation();
    e.preventDefault();
}, false);
            
dropbox.addEventListener("drop", function(e){
    e.stopPropagation();
    e.preventDefault();
            
    var dt = e.dataTransfer;
    var files = dt.files;
    
    // files[0]即为第一个文件
      
}, false);

For details, please refer to: Selecting files through drag and drop operations

I also recommend you an example I wrote:
Select image files - supports three input methods (input box selection, drag and drop selection, screenshot and paste three input methods)
