This example page is outdated. The demo on this page is now just a small fraction of the fully functional script that this prototype helped to create. See w:c:dev:ListFiles for the completed script!

This is an example of using JavaScript with AJAX to query the allimages API and put the results in a sortable table. The URL (see JavaScript section below) being used is:

(localwiki) + /api.php?action=query&list=allimages&ailimit=1000&aiprop=size&format=json

  • &format=json is used in the URL to put the information into JavaScript Object Notation (JSON) format so that it can be used with JavaScript
  • To detect images of a minimum size of 1 MB, you would need to add &aiminsize=1000000 into the URL. In this example, I did not set the minimum file size because my test wiki here doesn't have any images larger than 1 MB.
  • The script is not currently set up to detect differences between file types. e.g. videos will pop up in the results.

allimages-sorting-tableEdit

Name Size (bytes) Width (px) Height (px)
This row is needed to "trick" sortable into working properly, but it's hidden so that it won't affect anything. Note: This table uses JavaScript to call the allimages API, so if you copy this table, you also need to copy the JavaScript that goes with it. -1 -1 -1

JavaScript that goes with itEdit

$(function () {
	var $tbody = $('#allimages-sorting-table tbody');
 
	//********** URL FOR API CALL, YOU CAN CHANGE THIS **********
	var url = '/api.php?action=query&list=allimages&ailimit=1000&aiprop=size&format=json';
 
	// Callback function to execute with AJAX
	// Note: This function is highly dependent on the HTML structure of
	// the allimages-sorting-table. If you change the table, this function
	// will likely need to updated as well.
	function callback(data) {
		try {
			var newrows,
				image,
				title,
				allimages = data.query.allimages,
				len = allimages.length,
				i;
 
			for (i = 0; i < len; i++) {
				image = allimages[i];
 
				title = encodeURIComponent(image.title.replace(/ /g, '_'));
 
				newrows += '<tr><td><a href="/wiki/' + title + '">' + image.name + '</a>'
						+ '</td><td>' + image.size
						+ '</td><td>' + image.width
						+ '</td><td>' + image.height
						+ '</td></tr>';
			}
 
			$tbody.append(newrows);
		} catch (e) {
			$tbody.append('<tr><td colspan=4>An error occured while querying allimages API. See your JavaScript console for more details.</td></tr>');
			console.log('An error occured while querying allimages API:', e);
		}
	}
 
	// query the API
	if ($tbody.length > 0) {
		$.getJSON(url, callback);
	}
});
