Hello Chavo,

To access an iframes contents the source must be on the same domain.

Example :

Code:

$(function() {
    $('#emoticons').load(function() {
       $('#emoticons').contents().find('img').click(function() {
          $('#textArea').val($('#textArea').val() + $(this).attr('alt'));
       });
    });
});

And what codes i apply to iframe images? And it really must be hosted on forum?

On forumotion have an limit of maximum html modules?

The code I posted above shows how to access the iframes html contents. For the emoticon codes, it is done by the alt text of the image. We target this attribute and insert its value into the texarea.

To access the contents of an iframe, the iframe source must be on the same domain.

The max number of HTML pages you can have is 500. Please see this topic for limits :

So, i can put a texbox inside the frame and the person get it just pressing a button...

Have a possibility to switch automatically the theme when your internet is slow. 

And can apply a .css from the main frame to iframes on the page? And when switch the theme of the main frame switch on the iframe?

If you wanted to append a stylesheet to the iframe you can do :

Code:

$(function() {
    $('#myFrame').load(function() {
       $('#myFrame').contents().find('head').append('<link type="text/css" href="/mystyle.css" rel="stylesheet">');
    });
});

Two questions
This code will affect all pages on frame? If i go to another page it will be replaced by the theme of the page?

And how i modify this code for example make a list to choice the theme?

To apply to all frame pages you would need to append the style again, so you could do something like :

Code:

var setStyle = setInterval(function() {
    if ($('#myIframe').contents().find('#myStyle').length) return;
    $('#myIframe').contents().find('head').append('<link type="text/css" id="myStyle" href="mystyle.css" rel="stylesheet">');
},100);

You could set up a list of elements and have them run a function if clicked. You would need to clear the other functions when doing so. So, on click of the new style you would run a similar function above and kill your other intervals by calling clearInterval.

ex :

Code:

$('#mybutton').click(function() { clearInterval(setStyle) });
