用户从文件字段中选择文件时，是否发生JS事件？

Question

I would like to know if there is an event that I can call a JS function with that occurs when the user has selected a file for a file field. Or is there something similar?

What I am trying to do is append the name of the file to the page once the user has selected the file, thanks.

Answer 1

when a user selects a file, the file input "changes", so you'll want to use the change event.

$("#myinput").on("change",function(){
    console.log($(this).val());
})
