Enhance dojo.io.bind to execute embedded and linked script files

[[email protected]…]

Add an option into dojo.io.bind to execute any javascript in between <script></script> tags, and to automatically include any external scripts linked via <script src=""></script>

Here's a function that (pretty much) does the trick. Although I'm sure it could be cleaned up substantially. It just needs to be included in the dojo.io.bind function call.

---

executeScript = function (content) {

handle <script src="foo"> first var src = new RegExp?('<script.*?src=".*?"'); var repl = new RegExp?('<script.*?src="'); var matches = src.exec(content);

var semaphore = 0;

if (matches != null)

{ for (i = 0; i < matches.length; i++)

{

get the src of the script var scriptSrc = matches[i].replace(repl, ); scriptSrc = scriptSrc.substring(0, scriptSrc.length-1);

this evals remote scripts

dojo.io.bind({

url: scriptSrc, load: function(type, evaldObj) {/* do nothing */ }, error: function(type, error) {alert(type); alert(error); /* do nothing */ }, mimetype: "text/javascript", sync: true

});

}

}

Remove the script tags we matched

repl = new RegExp?('<script.*?src=".*?".*?</script>'); content = content.replace(repl, );

Next, handle inline scripts

Clean up content: remove inline script comments repl = new RegExp?('.*?$', 'gm'); content = content.replace(repl, '

');

Clean up content: remove carraige returns repl = new RegExp?('[

]', 'g');

content = content.replace(repl, ' ');

Match anything inside <script> tags

src = new RegExp?('<script.*?</script>', 'g');

matches = content.match(src);

For each match that is found... if (matches != null) { for (i = 0; i < matches.length; i++)

{

Remove begin tag

var repl = new RegExp?('<script.*?>', 'gm'); var script = matches[i].replace(repl, );

Remove end tag

repl = new RegExp?('</script>', 'gm'); script = script.replace(repl, );

Execute commands

setTimeout(script, 250);

}

}

}

This is in ContentPane? now (although Josh needs to add a fix to prevent reloading already loaded scripts). Does it need to be in dojo.io.bind, or some other more general place?

I'm not sure it does need to be anywhere but ContentPane?. It doesn't make sense in bind().
