js-sequence代码编写

js-sequence-diagrams depends on Snap.svg and Underscore.js (or lodash). You can download all these files manually, or use “bower install bramp/js-sequence-diagrams”.

Then include the following HTML:

<script src="webfont.js"></script>
<script src="snap.svg-min.js"></script>
<script src="underscore-min.js"></script>
<script src="sequence-diagram-min.js"></script>

and now you have two options. You can manually parse the text:

<div id="diagram"></div>
<script>
  var diagram = Diagram.parse("A->B: Message");
  diagram.drawSVG("diagram", {theme: 'hand'});
</script>

or use jQuery to do all the work:

<div class="diagram">A->B: Message</div>
<script>
$(".diagram").sequenceDiagram({theme: 'hand'});
</script>
