Give the element an ID attribute and then use JavaScript’s getElementById() function to access that element." This is only one of the methods, and the modern trend is rather to use the more dynamical methods getElementsByTagName('tag')[index], childNodes, nextSibling, previousSibling, parentNode... and to reduce the id refrence to a minimum necessary. “How do you access an element in an HTML document with JavaScript?

This is only one of the methods, and the modern trend is rather to use the more dynamical methods getElementsByTagName(‘tag’)[index], childNodes, nextSibling, previousSibling, parentNode… and to reduce the id refrence to a minimum necessary.

With the location or href property of the document object." Wrong. The correct answer is: With the location or with the location.href property of the window object. “How do you load a new URL in a browser?
With the location or href property of the document object.”

Wrong. The correct answer is: With the location or with the location.href property of the window object.

Indeed a novice JavaScript user should know how to do the items mentioned in the article. Hence the title “JavaScript Beginning Interview Questions.” I just find it ironic that many who claim advanced JavaScript skills fail to answer these questions.

Maybe I missed something but anyone who claims to be even a novice at JS should know most of the things on this list. Neat article however. - Leif P.S. For an example of what I mean, here's some of my javascript experience (which is very minimal, but uses many of the techniques described in this article): video.greenmangames.vze.com, affiliates.greenmangames.vze.com, graphics.greenmangames.vze.com, colorpicker.greenmangames.vze.com, citator.greenmangames.vze.com... etc. Interesting article… but I’m a very novice javascript user and knew how to do most of those things.

Here's hoping we do get some candidates that can answer these now. That would be an improvement. :) In response to your finely suggested questions: 1) Good idea. This question should definitely be added if they are getting the other correct. <a href="http://joeyjavascript.com/2007/04/25/javascript-difference-between-null-and-undefined/" rel="nofollow">JavaScript Difference Between null and defined</a> 2) If they claim to know OO principles this can be asked. 3) Data typing is another good suggestion. <a href="http://joeyjavascript.com/2007/08/07/javascript-data-types/" rel="nofollow">JavaScript Data Types</a> Kevin,

Obviously you're now going to get candidates that can answer these! How about a couple of additions: 1. What's the difference between null and Undefined? (to spot the philosophers:-) 2. How would you use JavaScript in an object-oriented manner? 3. What do you think about data typing in JavaScript? Nice article. Obviously you’re now going to get candidates that can answer these!
