clear iframe cache issue in IE9

Question

I am using iframe to load pdf. $('#iframe01').attr('src', url);

Everytime when loading new pdf file, it shows the old one for a very short period of time.

So, I am using $('#iframe01').find('body').html('') to clear the previous cached pdf when user click the different pdf file, it is working fine in Chrome.

However, when I test it in IE9, after opened the pdf and closed it, when click 2nd file, in console, it is saying: No such interface supported and crash.

Any reason for this happen?

Answer 1

好的， contentWindow.document.body.innerHTML = ''修复。

Answer 2

Try to add some extra data's in your URL like

$('#iframe01').attr('src', url + "?date="+new Date().getTime() );

this will be considered as every time the new url comes and erase the old data.

Hope this helps. But not tested.
