    <p>I am sorry if this is a dumb or easy question but I am fairly new to Javascript/jQuery. The past month I have really started to delve into the land of scripting and have seen two different, maybe three, ways people use <code>var</code> in Javascript/jQuery.</p> <p>The way I use a var is like so,</p> <pre><code>var nav = $('nav'); nav.hide(); </code></pre> <p>A very common way I have seen people use vars,</p> <pre><code>var nav = $('nav'); $(nav).hide(); </code></pre> <p>From the answers,</p> <pre><code>var $nav = $('nav'); $nav.hide(); </code></pre> <p>From what I have learned from searching through Google is what you typed inside the variable is saved there to later be used. I then figured if I wrote the $() around the var when I was using it, it would duplicate the $(). Yet both ways seem to work so I know it does not duplicate it and therefore can tell that it is the same thing.</p> <p>Is there a correct way to use <code>vars</code> or are both equally the same and it doesn't matter?</p> <p>I apologize again if this is a known answer and will be happy to remove it if someone can show me the original question but I couldn't find anything on it.</p> <p><em>A great bit of information from an answer that I didn't mark as the answer but I find to be very important.</em></p> <pre><code>var element = document.createElement("div"); $("body").append(element); $(element).hide(); </code></pre> <blockquote> <p>In the example above, $(element) is necessary, because it takes a DOM object and converts it to a jQuery selector. jQuery functions only work on jQuery selectors, so you couldn't simply do element.hide().</p> </blockquote>

    1. COYou should probably take a step back and make sure you understand: JavaScript is the language. jQuery is a framework. Also, jQuery sucks, especially since IE got in gear ;)

    2. COI am more familiar with jQuery due to the ease of writing it and am 100% understanding that jQuery is based off of javascript. I luckily am in a class right now for javascript so that should help. :D

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
