<script type= "Text/javascript" >//<! [Cdata[if (GetCookie (' Firefoxiframe ')) {document.write (' <p id= ' Addad "><a href=" cookie.html "> Click here to delete this iframe</a></p> '); document.write (' <iframe height= ' "width=" marginheight= "0" marginwidth= "0" frameborder= "0" src= "nAdPre.swf "></iframe>");} else{document.write (' <p id= ' Addad "><a href=" cookie.html "> click here to add a iframe</a></p> ');}//]] ></script>

Open the bug demonstration, because the cookie does not exist, the display of three Flash is implemented through the IFRAME
Click "Click here to add an iframe ad", Jump to a new page to write a cookie named Firefoxiframe
Click "Back" or the return button of the browser, back to the Bug demo page, found inside the IFRAME flash dislocation, that is, the location 2 of the IFRAME link Flash is not loaded, showing the location of 3 flash, position 3 of the display is the location of the 4 flash, The location 4 flash still exists.

If you write a cookie or delete a cookie, not through the browser's return, directly through the URL access, there will be no dislocation
simple analysis and Solution
It seems that when Firefox returns, JavaScript is re-executed, but the IFRAME is not re-loaded according to the SRC attribute, but instead is paired with a similar number to the IFRAME and SRC, and because the JavaScript is executed when it returns, Causes an IFRAME to be one (or one less), which results in a mismatch in the back.

above is guessing only, But this is really a bug,ie of Firefox (2.0.0.3) when the JavaScript is re-executed, and the IFRAME is re-loaded by SRC, and when opera returns, JavaScript does not re-execute and the page does not change. The

solution is to add a hidden iframe to the text, and the code above modifies the following code:

document.write (' <p id= "Addad" ><a href= "cookie.html" > click here to add a iframe</a></p> '); Modify the above code to become document.write (' <iframe src= ' # "style=" Display:none; " ></iframe> '); document.write (' <p id= "Addad" ><a href= "cookie.html" > click here to add a iframe</a></p> ');

The above is the Firefox return when the IFRAME display bug Solution _ Experience Exchange content, more relevant content please pay attention to topic.alibabacloud.com (www.php.cn)!
