Tooltipster can take a string as content. For example,
var myHTML = "Hello world";
instance.content(myHTML);
But the content cannot include HTML tags. You can't use this
var myHTML = "Hello <i>world</i>";
although this
var myHTML = "Hello <i>world</i>";
works.
What is the straightforward way to set a string of tagged HTML as the content of Toolstipster?
The problem was not Tooltipster. It was using Toolstipster with XHTML.
var myHTML = "Hello <i>world</i>";
instance.content(myHTML);
works just fine . . . in HTML but not in XHTML, as was being used here.
XHTML parses entities inside <script>
. To stop that, wrap the script inside a CDATA:
<script type="text/javascript">
//<![CDATA[
var myHTML = "Hello <i>world</i>";
instance.content(myHTML);
//]]>
</script>
