[Mapbender-dev] using jquery ...

[Christoph Baudson (WhereGroup)]

I would be very interested in a solution. I use the jQuery library in a 
separate frame, but want to locate html elements in another iframe.

Until now I didn't succeed. In this example

 > imported_$('div.test a').find('span').each(function(i) { ...

the variable imported_$ only *points* to the jQuery library in the 
remote frame, so 'div.test a' will only find the div tags in the iframe 
where jQuery is loaded, and not in the intended iframe. At least that is 
my interpretation ;-)

I tried to clone the jQuery-object with my own recursive function, but 
the depth is too deep and I get a stack overflow.

Maybe we can do a debug sprint together sometime?
