Hello,
We recently started using the Wonder Ajax framework (which is amazing
btw, well done guys), but we want to be able to detect if javaScript
is enabled on the client's browser.
I suspect this is a problem solved by many before, but I cannot seem
to find a reliable solution.
I have considered setting cookies using client-side javascript, then
checking for them server-side.
But conditions can arise where this might not work.
Checking client-side should be the simplest and more reliable way,
but I have hit a little problem.
The <noscript> condition is simple (no issues there)
The <script> condition is less simple. You have to use a
document.write('..');
The problem is now an escaping issue (as demonstrated below):
TheComponent.html
---------------------------
<noscript>
<webobject name = ClickedRemoveFromOrder> Remove </webobject>
</noscript>
<script type="text/javascript">
document.write('<wo:AjaxUpdateLink action =
"$clickedRemoveFromOrder" title = "Remove from basket" class =
"remove" updateContainerID = "$mediaItem.pk.toString"> Remove </
wo:AjaxUpdateLink>');
</script>
---------------------------
Generates:
---------------------------
<noscript>
<a class="remove" title="Remove from basket" href="/cgi-bin/
WebObjects/Shop.woa/wo/3.0.17.10.0.0.1.3.11.1.1.1.1.3.1.5.1.3.1">
Remove </a>
</noscript>
<script type="text/javascript">
document.write('<a href="javascript:void(0);" onclick="AUL.update
('246', {}, '3.0.17.10.0.0.1.3.11.1.1.1.1.3.1.5.1.3.3');"
title="Remove from basket" class="remove"> Remove </a>');
</script>
---------------------------
I believe I need to escape the following characters so that they can
be inserted into the document.write as a parameter.
' /
and probably a few more?
Is there a container I can use that will escape the generated HTML
automatically?
Or maybe an additional binding on AjaxUpdateLink (escapeForJavascript)?
Other suggestions welcome.
Thanks in advance,
Mark
