We started with the basics — like how to turn JavaScript on and off in your browser. We then quickly moved on to the basic syntax of JavaScript. We learned that you can include JavaScript within your HTML page, or you can place it in an external file — the choice is yours.</p> <p>We learned about some of the key concepts of JavaScript and that these concepts are pretty standard across most programming/scripting languages — concepts such as operators, variables and functions.</p> <p>We learned that intrinsic events enable you run a script in response to a user's action.</p> <div class="ad">  <div data-fuse="23059883629"></div> </div> <p>We covered some more of the standard programming concepts such as If statements, Switch statements and loops.</p> <p>We learned how to catch an error and present a friendly message back to the user (so as to not scare them off).</p> <p>Among the advanced topics were cookies, which enable us to "remember" a user by writing and reading a file on their hard drive. We learned how to present the date and time in a nice format, then we looked at arrays — another standard programming concept.</p> <p>Finally, we looked at the concept of unobtrusive JavaScript and how we can be more mindful of non-JavaScript users. In particular, ensuring our application still works for non-JavaScript users.</p> <h2>What Next?</h2> <p>Here are some <a href="/javascript/examples/">JavaScript examples</a> that you can use to base your own code on.</p> <p>Also check out the <a href="/jquery/tutorial/">jQuery Tutorial</a>. jQuery is a JavaScript framework that can make it easy to create cross-browser JavaScript applications that "just work".</p> <p>Another good one is the <a href="/json/tutorial/">JSON Tutorial</a>. JSON is data interchange format that you will probably find very familiar, now that you've seen how JavaScript works.</p> <ul class="pager"> <li><a href="/javascript/tutorial/unobtrusive_javascript.cfm"><i class="fa fa-long-arrow-left" aria-hidden="true"></i> Unobtrusive JavaScript</a></li> <li><a href="/javascript/examples/">JavaScript Examples <i class="fa fa-long-arrow-right" aria-hidden="true"></i></a></li> </ul> </article> <div class="sidebar"> <nav> <ul> <li> <h3><a href="/javascript/tutorial/">JavaScript Tutorial</a></h3> <ul> <li><a href="/javascript/tutorial/introduction.cfm">Introduction</a></li> <li><a href="/javascript/tutorial/how_to_enable_javascript.cfm">How to Enable JavaScript</a></li> <li><a href="/javascript/tutorial/javascript_syntax.cfm">JavaScript Syntax</a></li> <li><a href="/javascript/tutorial/javascript_popup_boxes.cfm">JavaScript Popup Boxes</a></li> <li><a href="/javascript/tutorial/javascript_html.cfm">JavaScript and HTML</a></li> <li><a href="/javascript/tutorial/external_javascript_file.cfm">External JavaScript File</a></li> <li><a href="/javascript/tutorial/javascript_operators.cfm">JavaScript Operators</a></li> <li><a href="/javascript/tutorial/javascript_variables.cfm">JavaScript Variables</a></li> <li><a href="/javascript/tutorial/javascript_functions.cfm">JavaScript Functions</a></li> <li><a href="/javascript/tutorial/javascript_events.cfm">JavaScript Events</a></li> <li><a href="/javascript/tutorial/javascript_if_statements.cfm">JavaScript If Statements</a></li> <li><a href="/javascript/tutorial/javascript_switch_statement.cfm">JavaScript Switch Statements</a></li> <li><a href="/javascript/tutorial/javascript_while_loop.cfm">JavaScript While Loop</a></li> <li><a href="/javascript/tutorial/javascript_for_loop.cfm">JavaScript For Loop</a></li> <li><a href="/javascript/tutorial/javascript_try_catch.cfm">JavaScript Try Catch</a></li> <li><a href="/javascript/tutorial/javascript_escape_characters.cfm">JavaScript Escape Characters</a></li> <li><a href="/javascript/tutorial/javascript_void_0.cfm">JavaScript Void(0)</a></li> <li><a href="/javascript/tutorial/javascript_cookies.cfm">JavaScript Cookies</a></li> <li><a href="/javascript/tutorial/javascript_date_and_time.cfm">JavaScript Date and Time</a></li> <li><a href="/javascript/tutorial/javascript_arrays.cfm">JavaScript Arrays</a></li> <li><a href="/javascript/tutorial/two_dimensional_arrays.cfm">Two Dimensional Arrays</a></li> <li><a href="/javascript/tutorial/innerhtml_in_javascript.cfm">JavaScript innerHTML</a></li> <li><a href="/javascript/tutorial/unobtrusive_javascript.cfm">Unobtrusive JavaScript</a></li> <li><a href="/javascript/tutorial/javascript_summary.cfm">JavaScript Summary</a></li> </ul> </li> <li><h3>JavaScript Reference</h3> <ul> <li><a href="/javascript/examples/" title="">JavaScript Examples</a></li> <li><a href="/javascript/javascript_reserved_words.cfm" title="">JavaScript Reserved Words</a></li> <li><a href="/javascript/javascript_event_handlers.cfm" title="Introduction to the 12 JavaScript event handlers">JavaScript Event Handlers</a></li> <li><a href="/javascript/javascript_date_and_time_functions.cfm" title="Full listing of all JavaScript methods for dealing with date and time.">JavaScript Date and Time Functions</a></li> </ul> <li><h3>jQuery</h3> <ul> <li><a href="/jquery/tutorial/" title="">jQuery Tutorial</a></li> <li><a href="/jquery/examples/" title="">jQuery Examples</a></li> </ul> </li> <li><h3>JSON</h3> <ul> <li><a href="/json/tutorial/" title="Data format for exchanging data between applications and different environments.">JSON Tutorial</a></li> </ul> <li> </ul> </nav> <div class="ad ad-left">  <div data-fuse="23059511712"></div> </div> </div> <div class="ads"> <div class="ad ad-right">  <div data-fuse="23059883626"></div> </div> </div> </div> <div class="searchbox-bottom"> <form action="/search/" id="cse-search-box-bottom" class="site-search"> <div> <input type="hidden" name="cx" value="partner-pub-6331358926293806:npmuvy-i8kk"> <input type="hidden" name="cof" value="FORID:10"> <input type="hidden" name="ie" value="ISO-8859-1"> <input type="text" name="q" size="30" class="site-search-input"> <button type="submit" name="sa" class="site-search-button"><i class="fa fa-search"></i></button> </div> </form> <script src="//cse.google.com/cse/brand?form=cse-search-box-bottom&lang=en"></script> </div> <footer> <p class="about"><a href="/"><i class="fa fa-home"></i> Home</a> | <a href="/about.cfm" rel="nofollow">About</a> | <a href="/contact.cfm" rel="nofollow">Contact</a> | <a href="/terms_of_use.cfm" rel="nofollow">Terms of Use</a> | <a href="/privacy_policy.cfm" rel="nofollow">Privacy Policy</a></p> <p>© Copyright 2000 -
