I\u2019ve lost count of the number of Javascript scripts I\u2019ve seen floating around that include the equivalent of the following code snippet:<\/p>\n
if (document.all) {
\nelement = document.all[id];
\nelse {
\nelement = document.getElementById(id);
\n}<\/p>\n
document.all was introduced in Internet Explorer 4, because the W3C DOM hadn\u2019t yet standardised a way of grabbing references to elements using their ID. By the time IE 5 came out, document.getElementById() had been standardised and as a result, IE 5 included support for it.<\/p>\n
IE 5 was released in September 1998. A popular browser statistics site (insert usual disclaimer as to the reliability of any stats but your own here) show IE 4\u2019s market share to be in the region of 1%. Even Netscape 4 has more users than that!<\/p>\n
Don\u2019t use document.all. document.getElementById() is supported by every Javascript supporting browser released since 1998.<\/p>\n","protected":false},"excerpt":{"rendered":"
