For example, it is possible that the layout and definition of a Table visualization in TIBCO Spotfire could change in a future version. This also means that you cannot assume how other elements outside your DOM are defined in order to be compatible with future versions of TIBCO Spotfire. Thus if you add a div element in the Text Area that your JavaScript operates on, you are safe. This means that the JavaScript should only change parts of the HTML DOM that reside in the Text Area and that is defined in the the HTML of the Text Area.

See also How to include your own instances of jQuery and jQueryUI in Text Areas.Īs a general rule the JavaScript should only modify elements in the HTML code that you have created and have control over yourself. Your use of any of those libraries is entirely at your own discretion and is not supported or warranted by TIBCO. TIBCO provides no guarantee whatsoever of the correctness, usability or compatibility of the libraries in scope. This means that there are a lot of JavaScript libraries defined by TIBCO Spotfire and third parties in scope, including JQuery ($) and JQueryUI. The first important thing to know is that the JavaScripts you add to the Text Area will execute in the same environment as the JavaScripts defined by TIBCO Spotfire to implement all functionality in the Text Area and other TIBCO Spotfire visualizations. The intended use of JavaScripts in the Text Area is to decorate your own elements and make them more interactive, for example adding highlight effects on elements or creating an interactive layout. JavaScripts can be inserted into a Text Area via the Edit HTML option and then clicking the “Insert JavaScript” button in the toolbar. I have prepared some basic HTML with a little bit of styling so we can put the onclick event into real-world practice.This article contains best practices and recommendations for how to develop custom JavaScript code in Text Areas in TIBCO Spotfire ® analysis files in a supportable and maintainable way so the analysis files will continue to work with future versions of TIBCO Spotfire. In JavaScript, you invoke a function by calling its name, then you put a parenthesis after the function identifier (the name). The value it takes, which is the function you want to execute, says it all, as it is invoked right within the opening tag. Note that the onclick attribute is purely JavaScript. You place the JavaScript function you want to execute inside the opening tag of the button.
This could be when a user submits a form, when you change certain content on the web page, and other things like that. The onclick event executes a certain functionality when a button is clicked.
How to Use the onclick event in JavaScript Then we'll see how the more modern "click" eventListner works, which lets you separate the HTML from the JavaScript. In this tutorial, we are going to explore the two different ways of executing click events in JavaScript using two different methods.įirst, we'll look at the traditional onclick style that you do right from the HTML page. Buttons, on the other hand, are usually manipulated by JavaScript events so they can trigger certain functionality. Links take you to a certain part of the page, another page of the website, or another website entirely. Whenever you visit a website, you'll probably click on something like a link or button.
