jQuery.Ruler
jQuery.Ruler is a jQuery plugin born out of sheer curiosity and on a whim. It dynamically places rulers on the x & y axes, with tick marks every 5 pixels & labels every 50 pixels. Should you wish, there are options to enable tracking of the cursor position with a crosshair and/or a box showing the coordinates within the ruler space.
Usage
Add jQuery & the Ruler plugin. jQuery.Ruler requires jQuery v1.8.0 or greater. At the time of writing jQuery v1.8.3 is the latest stable release.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> <script src="js/jquery.ruler.js"></script>
Script
$(function() { $('body').ruler(); });
Licensing
jQuery.Ruler is dual licensed under the MIT & GPL licenses.
Options
Options are set with an object as an argument to the .ruler() function call. All options are optional; the plugin will use the default values.
$(function() { $('body').ruler({ vRuleSize: 18, hRuleSize: 18, showCrosshair : false, showMousePos: true }); });
