Using DOM elements in Javascript – Part 3

Saturday, February 16th, 2019 by Servage
Inner HTML gives us a simple method for accessing and changing the text and markup inside an element. It behaves differently from the methods we’ve covered so far. Let’s say we need a quick way of adding a paragraph of text to the first element on our page with a class of intro: var introDiv = document.getElementsByClassName("intro"); introDiv.innerHTML = "<p>This is our intro text</p>"; The second statement here adds the content of the string to introDiv (an element with the class value “intro”) as a real live element because innerHTML tells JavaScript to parse the strings “<p>” and “</p>” as markup. style The DOM also allows you to ...

Here we will discuss about some more id attributes syntaxes. By id attribute value getElementById() This method returns a single element based on that element’s ID (the value of its id attribute), which we provide to the method as an argument. For example, to access this particular image: <img src="photo.jpg" alt="" id="lead-photo">' We include the id value as an argument for the getElementById() method: var photo = document.getElementById("lead-photo"); By class attribute value getElementsByClassName() Just as it says on the tin, this allows you to access nodes in the document based on the value of a class attribute.

We have earlier seen an introduction to DOM Nodes and Structures in JavaScript. Now let’s discuss some advanced DOM Management Concepts to make best use of it in Web Development. The document object in the DOM identifies the page itself, and more often than not will serve as the starting point for our DOM crawling. The document object comes with a number of standard properties and methods for accessing collections of elements. Just as length is a standard property of all arrays, the document object comes with a number of built-in properties containing information about the document. We then wind our way to the element ...

Beautiful charts enrich your data

Saturday, December 29th, 2018 by Servage
chartjsMany websites display data tables as part of their content. This is easily done with the <table> element in HTML, which is invented for the purpose of showing tabular data. However, graphs and charts have been more cumbersome for years, because they are more complex content elements. Initially charts were generated as images which could be included in the web page. Later the Flash technology has made more interactive charts possible, however the problems with Flash and its limitations have rendered those kinds of charts unpopular. Lately HTML has evolved a lot, and with the introduction of the <canvas> element more advanced drawings on pages have become possible. With the <canvas> element ...

The later two languages allow you to define variables and use them in calculations you can perform in your stylesheet. Also code blocks allow for ...
