Disable submit button on error validating input file when using krajee file input plugin

I am using plugins.krajee.com/file-input

, and I cannot find a way to disable the Upload or Submit button on my form when a validation error has occurred eg minImageWidth

.

$('.file').fileinput({
        language: 'en',
        showUpload: false,
        allowedFileExtensions : ['jpg', 'png','gif'],
        maxFileSize:1024,
        minImageWidth:286,
        minImageHeight:322
     });

      

        
        
        
      

    

How to use $('.file').fileinput('disable');

when minimum image width parameter returns validation error?
