Questions about uploading pictures

First of all to declare the first time the blogger is uploading pictures used by someone else to write good

At first, the backstage need is a Base64 image address later, I said I need an upload image object

Just like this.

First, you need a new Formdata object

var New FormData ()

Formdata parentheses fill in your form form

If you are uploading multiple pictures, use the file property of input to add the Multiple property

<input type= "File" name= "file" id= "Upfile-hj" multiple>

Then loop through the selected picture to save the picture in Formdata's prototype and finally submit the formdata to the background
