上传多个文件后启用提交按钮 [英] Enable submit button after uploading more than 1 file

问题描述

所以我在这里找到了部分答案，我需要启用一个提交"按钮，但仅在上传多个文件之后.当我仅上传1个文件时，它会自动启用，但是我需要的是直到我提交第二个文件后才能启用提交功能.

so I found this partially answered here, what I would need is to enable a submit button, but only after uploading more than 1 file. When I upload just 1, it automatically enables, but what I would need is that the submission doesn´t get enabled until I submit the second file.

$(document).ready(
function(){
    $('input:submit').attr('disabled',true);
    $('input:file').change(
        function(){
            if ($(this).val()){
                $('input:submit').removeAttr('disabled'); 
            }
            else {
                $('input:submit').attr('disabled',true);
            }
        });
});

        $('input:file').change(
            function(){
                if ($("#file1").val() && $("#file2").val()){
                    $('input:submit').removeAttr('disabled'); 
                }
                else {

HTML:

<form action="#" method="post">
    <fieldset>
        <input type="file" id="file1"/>
    </fieldset>
   <fieldset>
        <input type="file" id="file2"/>
    </fieldset>
    <fieldset>
