Hi moon, Thanks very much for that! Yes, replacing $ with jQuery worked (regardless of whether I used single or double quotes around #myDiv). I’ll be careful with $ signs in %html directives with string interpolation then☺.
Note that the alert box pops up 3 times in all. Did you get that when you ran the code? This relates to my previous postscript about the code being executed 3 times in a paragraph. Is this expected behaviour?! Thanks, Lucas.

It might help.

Here’s a very simple example that illustrates the problem. Try pasting this into a Zeppelin paragraph: print(s"""%html <div id="myDiv" style="height:400px"></div> <script> $('#myDiv').ready(function() { alert('My div is loaded!'); }); </script> """) When I run the paragraph I get these errors: <console>:1: error: invalid string interpolation: `$$', `$'ident or `$'BlockExpr expected print(s"""%html <div id="myDiv" style="height:400px"></div> ^ <console>:3: error: unclosed character literal $('#myDiv').ready(function() { ^ Does anyone know how to fix these errors please? (I can get rid of the second error by replacing the single quotes with double quotes in $('#myDiv') but I’m not sure that’s the right thing to do!) Many thanks, Lucas. PS Incidentally I’ve noticed in the browser’s Javascript console that the paragraph seems to get executed 3 times! Is this expected behaviour? I’m using a standalone installation of the binary zeppelin-0.5.0-incubating.
