Document.getElementsByTagName ("*") Or document.all

document.getElementsByTagName("*") works for IE / Firefox / Opera, but does not work for Chrome and Safari.

document.all works for IE / Chrom / Safari, but does not work for Firefox.

How can I handle this?

document.allshould be avoided as this is not up to standard. Instead, you can use document.getElementById()to Private Node or use $("*")To select all elements using jQuery.

However, if you want to use document.all, then make sure the tag is <!DOCTYPE>removed from your page, and the xmlns attribute is also removed from your tag <html>.

- :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">


<html>

FireFox 19.0.2 document.all .

:. <!DOCTYPE>, , - , , document.all script, .

, , , , <!DOCTYPE>, document.all .

:

if (document.all !== undefined)
{
   allElements = document.all;
}
else
{
   allElements = document.getElementsByTagName("*");
}


allElements = document.all ? document.all : document.getElementsByTagName("*");
