Image upload using Froala WYSIWYG editor

image_upload.js

  $(function() {
      $('.selector').editable({
          // Set the image upload parameter.
          imageUploadParam: 'file_param',

          // Set the image upload URL.
          imageUploadURL: '/upload_path',

          // CORS. Only if needed.
          crossDomain: false,

          // Set the image error callback.
          imageErrorCallback: function (data) {
              // Bad link.
              if (data.errorCode == 1) {
                console.log ('bad link')
              }

              // No link in upload response.
              else if (data.errorCode == 2) {
                console.log ('bad response')
              }

              // Error during file upload.
              else if (data.errorCode == 3) {
                console.log ('upload error')
              }
          }
      })
  });
