How to expand all categories of this treeview
Rickie replied to Andres ControlGroup's topic in JavaScript
Are you wanting them to stay expanded or are you looking for them to then be closed by user click? -
Thank you for your response. I am curious to know more about why you wouldn't recommend the first one because of the onload HTML attribute? The first one is from W3SCHOOLS tutorial and I tend to think most of the time W3SCHOOLS would show the best ways for learners.

Hi, I've been doing a few tutorials for creating a canvas and I have came across 2 ways in doing this and hoping someone may be able to explain why you would do over one way instead of the other. W3SCHOOLS tutorial: <!DOCTYPE <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Mazing</title> <link rel="stylesheet" type="text/css" href="css/style.css"> </head> <body onload="startMazeGame()"> <script> function startMazeGame() { mazeArea.start(); } var mazeArea = { canvas : document.createElement("canvas"), start : function() { this.canvas.width = 500; this.canvas.height = 500; this.context = this.canvas.getContext("2d"); document.body.insertBefore(this.canvas, document.body.childNodes[0]); } } </script> </body> </html> Various tutorials show it done this way, including Mozilla ballgame guide: <!DOCTYPE html> <html> <head> <title>Game</title> <meta charset="UTF-8"/> <style> * { padding: 0; margin: 5; } canvas { margin: 0 auto; display: block; background: #eeee; } </style> </head> <body> <canvas id="myCanvas" width="480" height="330"></canvas> <script> var canvas = document.getElementById("myCanvas"); var ctx = canvas.getContext("2d"); </script> </body> <html> Many thanks.
