HTML SVG connect

jQuery plugin for drawing responsive paths between arbitrary HTML elements (with SVG).

Install

Load jQuery and the plugin:

<script src="jquery.min.js" type="text/javascript"></script>
<script src="jquery.html-svg-connect.js" type="text/javascript"></script>

or install with npm:

npm install html-svg-connect

Usage

Attach it to your container element on DOM ready, and define your paths as an array. Each path is an object with the start and end elements defined as CSS selector IDs:

(The elements don't have to be different; you can specify that any one element connects with any number of different elements.)

<script type="text/javascript">
    jQuery(document).ready(function($) {
      $("#svgContainer").HTMLSVGconnect({
        paths: [
          { start: "#red", end: "#aqua" },
          { start: "#purple", end: "#green" }
        ]
      });
    });
</script>

This will draw an SVG graphic with two pipes between the respective elements, and recalculate them as the window re-sizes.

Paths can also be added on-demand after loading (e.g., after an AJAX call), by calling addPaths with an array of path objects to add (this array has the same options available as when initialising paths).

var newPaths = [
  { start: "#red", end: "#green" }, 
  { start: "#aqua", end: "#green" }
 ];
$("#svgContainer").HTMLSVGconnect("addPaths", newPaths);

Options

These are defined as properties at the same level as the paths property.

Name	Type	Description	Default
stroke	string	Path colour	#000000
strokeWidth	integer	Path thickness (px)	10
orientation	string	Whether the path begins/ends from the side of the element or from the top/bottom. Options: [horizontal | vertical | auto]	auto
offset	integer	Number of pixels added to the path before the first curve.	0
class	string	Path class (css) name.	empty

The global options can also be overridden on a per path basis:

{
  stroke: "#00FF00",
  strokeWidth: 12,
  class: "",
  paths: [
    { start: "#red", end: "#aqua", stroke: "#FF0000", strokeWidth: 8 },
    { start: "#purple", end: "#green", orientation: "vertical", offset: 20, class: "dashed-blue" }
  ]
}
