document.getElementById("someId") Vs. someId

This question might seem silly, but what's the difference between accessing an element (with id "someId") using document.getElementById("someId") Vs. just typing someId ?

eg:

document.getElementById("someId").style.top = "12px";

vs

someId.style.top = "12px";

Here's a sample code http://jsfiddle.net/pRaTA/ (I found that it doesn't work in firefox)

Solution

  • The difference is that while someId works in some browsers, document.getElementById("someId") actually complies with the W3C standard.
