Below I will share with you a JS implementation method to obtain the value of input[file] and display it on the page. It has a good reference value and I hope it will be helpful to everyone.

The example is as follows:

$(document).on('change', '.photo-box .file', function () {
  //alert($(this).val());
  function getObjectURL(file) {
    var url = null;
    if (window.createObjectURL != undefined) { // basic
      url = window.createObjectURL(file);
    } else if (window.URL != undefined) { // mozilla(firefox)
      url = window.URL.createObjectURL(file);
    } else if (window.webkitURL != undefined) { // webkit or chrome
      url = window.webkitURL.createObjectURL(file);
    }
    return url;
  }
  var objUrl = getObjectURL(this.files[0]);
  console.log("objUrl = " + objUrl);
  var html = &#39;<p class="photo-box"><img src="&#39; + objUrl + &#39;" alt=""><p class="photo-btn"><p>删除</p></p></p>&#39;;
  $(this).parent().parent().append(html);
})

The above is what I compiled for everyone, I hope it will be helpful to everyone in the future.
