In this series we are using the IndexedDB API to create a basic note-keeping utility within a Web page. In the first part of the series we setup the HTML5 page elements and started IndexedDB processing by attempting to open the database. In this part we will be working on creating the object store, which is how we define the structure of the note database. In the final two parts of the series we will handle inserting, deleting and querying notes. This is part 2 in a series of 4 tutorials: Setup and opening the...
Accept it. Under the particular domain of web development, Python has offered much more than we expected it to in the early 2000’s. It now offers multiple pre-built web frameworks that even a novice coder can utilize for the development of complex applications. Today, we will witness it. Today, we will go through the process of building a dynamic web form using one of its frameworks called Web2Py on a local machine/server. In the progression of this tutorial, you will be able to learn how dynamic web...
Do you work on multiple sites at a time? Then no doubt you would love to improve your speed and your overall development workflow. Think of what it takes to set up WordPress the old school way: Downloading the latest version. Extracting the downloaded zip file. Creating a new database. Creating wp-config.php file. Developing WordPress sites has never been easier with WAMP and Simple WordPress Auto Installer. The Auto Installer script is now available that allows you to add a WordPress install within...
I recently developed an application that sent variables into a mathematic function. This function needed to have a numeric count of the exactly how many zeros there were in a certain array. For this snippet, we can use both numeric and text based arrays. I printed it using this code: Our two example arrays will be: $array_num = array(1, 1, 1, 2, 3, 4, 4, 4, 4, 4, 5, 6); $array_text = array(apple, apple, apple, orange, banana, banana); We then put this array into array_count_values() $count_array_num =...
With hundreds of millions of users entering hundreds of billions of queries into major search engines such as Google, Yahoo and Bing, the importance of designing a site to be search-engine friendly cannot be underestimated. However, even the most experienced designers and developers can make simple mistakes that can cost their site thousands of views and (potentially) uncounted revenues. HTML Issues ... Sometimes, the “old-fashioned” methods are still the most effective. While many SEO...
Web developers have a fond love for open source tools not only because these tools are generally free of cost, but they can be modified in any way the developer sees fit. That is actually where the free in free/open source software comes from. While .NET and other paid technologies and tools do have their place on the Web, it really is open source tools and applications that power it. There are thousands of great open source applications and picking the best among them is really hard since so many people have...
Indexed Database (IndexedDB) is an API for storing data at client side and a proposed standard, still in the relatively early stages of development. With the IndexedDB API, developers can store data objects within the user's browser. In this tutorial series we will explore the basics of this emerging technology by building a simple note-keeping facility for a Web page or site. Users will be able to add and delete notes, with past notes automatically displaying when the user revisits. The notes are...
Whether it is a list of products you are promoting, published ads or other elements on the sidebar, you will likely want to have these elements in view at all times even when scrolling. By using JQuery, you can make this possible. To do this, use the code snippet below: //keep element in view (function($) { $(document).ready( function() { var elementPosTop = $('#sidebar-ads').position().top; $(window).scroll(function() { var wintop = $(window).scrollTop(), docheight = $(document).height(),...
