Solved: jQuery In A Sandbox
Guys, forget all that crap I wrote precedent emails ... I did not think
about a truly simple change that will not affect anything, will be extremely
simple to maintain, and will make jQuery automatically "sandboxable"
This is my latest snippet via Elsewhere:
// the callback you would use for ready (with $ as jQuery argument)
function onDocumentReady($){
$("body").html("test");
};
new Elsewhere("jquery-1.3.2.js")
.execute(function(onDocumentReady){
(parent.jQuery = jQuery)(function(){
onDocumentReady(jQuery);
});
}, [
onDocumentReady
])
;
That's it ... and this is all I have done to jQuery library itself:
line 12, begninning of the closure ...
(function(*document*){
line 4376, the end of the closure and its call:
})(*parent.document || document*);
With this ridiculous change, jQuery becomes instantly loadable via iframe or
main document.
Best Regards,
Andrea Giammarchi
