I’ve always been an avid gamer going back to the late 80’s with the Nintendo (NES) system, then the Sega Mega Drive and Game Boy in the 90’s, then onto the Playstation. I’ve always wanted to make games but back then it was nearly impossible for an indie dev. That was until the invention

The $() function is an alias of jQuery() function, at first it looks weird and makes jQuery code cryptic, but once you get used to it, you will love it’s brevity. $() function is used to wrap any object into jQuery object, which then allows you to call various method defined jQuery object. You can even pass a selector string to $() function, and it will return jQuery object containing an array of all matched DOM elements. I have seen this jQuery asked several times, despite it’s quite basic, it is used to differentiate between developer who knows jQuery or not.

each() function is like an Iterator in Java, it allows you to iterate over a set of elements. You can pass a function to each() method, which will be executed for each element from the jQuery object, on which it has been called. This question sometime is asked as a follow-up of the previous question e.g. how to show all selected options in alert box. We can use the above selector code to find all the selected options and then we can use the each() method to print them in an alert box, one by one, as shown below:

$('[name=NameOfSelectedTag] :selected').each(function(selected){
alert($(selected).text());
});

The text() method returns text for that option.

Method chaining is calling another method on the result of another method, it results in clean and concise code, single search over DOM so better performance.

Make sure you know all the relevant news and blogs. You should be reading them regardless, but doing so on a daily basis during your job search is important. Be ready to talk casually and fluently about the latest web trends.

HTML elements communicate to the browser how to render text. When surrounded by angular brackets <> they form HTML tags. For the most part, tags come in pairs and surround text.

o link an image, use <img> tags. You need specify the image in quotes using the source attribute, src in the opening tag. For hyperlinking, the anchor tag, <a>, is used and the link is specified in the href attribute. Text to be hyperlinked should be placed between the anchor tags. Little known fact: href stands for “hypertext reference.” When linking to an email, the href specification will be “mailto:send@here.com.” See examples below:
