Question

<input id="img" type="file" name="img" accept="image/*">

And this is the JQuery code:

$('#img').change(function(){

    if($('#this').val() === '') { 

        $("#subm").remove();

    }  else {

         $('<button id="subm" type="submit">Press</button>').insertAfter('#advice');

   }

});

I’m trying check if the input file is empty, if is empty, and exist a button called subm, I delete it, but if the input file has a file, I create that bottom. The problem is that, if there’s a submbotton, because I select file, and after I change the input, let it empty, JQuery doesn’t delete it.

How can I delete a button, created by JQuery, if an input file is empty?

Thank’s advance!

Answer 1

$('#this') should be $(this), $('#this') matches an element with id=this
