当我使用多个文件上传字段时,它不起作用

    当我在一个页面中使用单个文件上传时,它工作正常,但当我在一个页面中使用多个字段时,它不工作。我想通过类和动态来解决问题 id 我不想在一页上花太多时间如果有人知道,请告诉我。

    代码url: https://codepen.io/tushar-kumawat/pen/WYyKYG

    下面是JavaScript代码:

    $('#chooseFile').bind('change', function () {
        var filename = $("#chooseFile").val();
        if (/^\s*$/.test(filename)) {
            $(".file-upload").removeClass('active');
            $("#noFile").text("No file chosen..."); 
        } else {
            $(".file-upload").addClass('active');
            $("#noFile").text(filename.replace("C:\\fakepath\\", "")); 
        }
    });

    $('.chooseFile, .chooseFile2').bind('change', function () {
      var filename = $(this).val();
      var $Upload = $(this).closest(".file-upload");
      if (/^\s*$/.test(filename)) {
        $Upload.removeClass('active');
        $(".file-select-name", $Upload).text("No file chosen..."); 
      }
      else {
        $Upload.addClass('active');
        $(".file-select-name", $Upload).text(filename.replace("C:\\fakepath\\", "")); 
      }
    });
