Prototype: extending elements with Element object in an iframe seems not working
Hi,
I just started learning prototype, and I encountered a problem
while trying to use Element.extend with iframe content:
/
**********************************************************************/
// I create an iframe and insert it in my document:
var iframe = $(document.createElement("iframe"));
document.getElmentsByTagName("body")[0].appendChild(iframe);
// I create content in for my new iframe:
iframe.contentDocument.write("<html><head></head><body></body></
html>");
// I get the iframe body element:
var body = iframe.contentDocument.getElementsByTagName("body");
//I create a div element in the iframe, and extend it with Element
properties:
var div = $(document.createElement("div"));
// I insert the div element in the iframe body:
body.appendChild(div);
// Then I try to absolutize the position of my div element...
div.absolutize();
// ... and I get the following error message:
// div.absolutize is not a function
// If I try to use the depreciated Position object...
Position.absolutize(div);
// ...then I got another interesting error message:
// element.getStyle is not a function
// which is an error that occurs in the absolutize Element method
call
// absolutize: function(element) {
// element = $(element);
// -----> if (element.getStyle(''position'')
=''absolute'') return;
/
***********************************************************************/
It seems that when I insert the element in the iframe, then it is not
anymore able to be extended with Element methods and properties...
Did anyone ever meet this kind of problem?
How did you issue?
Thanks,

Interesting. I think the main problem you are running into is that everything in the iframe has been sandboxed away from the parent, so none of the prototype methods that you are expecting to be there, will be there. -justin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.
