How to convert Prototype to jQuery?

Question

JavaScript

Guys, please help me to convert Prototype to jQuery.
Or advise documentation or a site where it can be made.

document.observe('dom:loaded',  function(){
  var loadButton = $('upload_button');
  var loadButtonValue = $F(loadButton);

  new AjaxUpload(loadButton, {
    name: 'photos[]',
    multiple: true,
    debud: true,
    action: './ajax.php?module=<?=$this->module_id?>&action=10',
    data: {
      issue: '<?=$issue?>'
    },
    onSubmit : function(file, ext){
      loadButton.value = 'Загружается...';
      this.disable();
      if (!(ext && /^(jpg|png|jpeg|gif)$/i.test(ext))){
              alert('Error: неверный формат файла изображения.');
              return false;
          }
    },
    onComplete: function(file, response){
      loadButton.value = loadButtonValue;
      this.enable();
      if(response.length) alert(response);
      new Ajax.Request("./ajax.php?module=<?=$this->module_id?>&action=4", {
        method: "post",
        parameters: { issue: '<?=$issue?>' },
        onSuccess: function(transport){
          $('photosPhotosAll').update(transport.responseText);
          photosLoadContent.defer();
        }
      });
    }
  });

  photosLoadContent();
});

Thank you very much in advance!

Answer 1

dom:loaded -> $(document).ready(function () {...});
new Ajax.Request -> $.ajax
And anyway, replace the file upload with this plugin: Dropzone.js
