更改事件未在IE中首次触发

Question

$(this).find('.custom-file-input').trigger('click');
$(this).find(".custom-file-input").off().on('change', function (){
....
}

Above is my code snippet, I am trying to trigger the click of a file upload input, which opens the file open dialog and then on change, I am trying to execute some code. In IE, for the first time, It doesn't work.

While in chrome and firefox, its working with success every time.

Answer 1

did you try changing the order?

$(this).find(".custom-file-input").on('change', function (){
....
}
$(this).find('.custom-file-input').trigger('click');
