That gave me more elements than I wanted. It would have been too hard
to then step through the array and work out that was actually meant to
be executed. Here's what I currently have working. I know that it is
a hack way of doing it but it seems to be the only way of getting an
array instead of just the first / last match:
var scripts=(cont.indexOf("<script>")!=-1) ?
cont.substring(cont.indexOf("<script>")).split("</script>") : [];
for (var i=0; i<scripts.length; i++)
scripts[i]=scripts[i].substring(scripts[i].indexOf("<script>")+8);
// this seems to be needed as the last element is always wrong.
if (scripts.length>1) scripts.length--;
for (var i=0; i<scripts.length; i++) alert(scripts[i]);
If someone knows of a better way, please help me. It seems a very dodgy
method of simply extracting tags from a string.
I should have a working example up in a few days. It uses a java
applet to download a url and then reads through it and extracts the
<title>, <body> and <script> tags. This should allow for dynamic
loading of content without the need for Loadpanel and simply extending
the setHTML method of a dynlayer.
