JavaScript

General

• JavaScript or JQuery can be used to program dynamic effects on web pages easily and across browsers or to make web applications more comfortable
• Our websites already contain jQuery
  All functions of this JavaScript library can be used
• Additional JavaScript code should always be integrated via a separate file (do not use inline code!) – integration is done via variable $javascript in the page header
  • $javascript[] = 'example/code.js'
• Typical application scenarios include:
  • dynamic manipulation of web pages
  • plausibility check (data validation) of form input before submission
  • Display of dialog boxes and pop-ups
  • Sending and receiving data without reloading the page in the browser (Ajax)
  • Suggestion of search terms during input
• The possibilities of JavaScript or JQuery are very manifold, therefore use:
  • the introduction and some usage examples in the TUCAL documentation
  • the official JQuery documentation
