Re: Perl, JavaScript and quoting/escaping

Actually I solved it half-way: The problem is less the quoting on the perl side, but what ends up in the html output:

\" becomes " - so inside the href="" we can use the single-quote ' to differentiate things. And if in these single-quotes values need to be presented we double quote \\' so the \' ends up in the html, like example.jsfunction('<a href=\'\'></a>')

But still I am in trouble if I need to add yet another nested layer of quoted values, for example example.jsfunction('<a href=\'\' onclick=\\'alert('test')\\'></a>') - what shoudl I do with the quotes around test? Any ideas?

Update:
I've found out that, at least in Firefox, using entities works: example.jsfunction('<a href=\'\' onclick=\\'alert("test")\\'></a>') - but is that portable?

As the prior poster said: use perl's "bring your own quote characters" to rescue you. Leave ' and " for javascript's feeble mind.	[reply]

oops - a simple typo in the post, code was ok.	[reply]

Generally, as long as you keep using the same type of quote, you double the \'s for each nested level, so try: `example.jsfunction('<a href=\'\' onclick=\\'alert(\\\\'test\\\\')\\'>< +/a>')` [download]	[reply] [d/l]

That would only work for if all of JS, HTML and Perl used "\" to escape. HTML doesn't. Assuming you had the right number of slashes — you don't — you're code results in the following HTML: `<a href='' onclick='alert(\' <- Nice JS! test\')' <- eh? ></a>` [download]	[reply] [d/l]
