Include the necessary YUI CSS and JavaScript files
You can find out the YUI file dependencies here: [1]
Serve the files needed by the Logger Conrol from YUI servers by defining the following in your widget HTML file:
<head>
<!-- css -->
<link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.5.1/build/logger/assets/skins/sam/logger.css">
<!-- js -->
<script type="text/javascript" src="http://yui.yahooapis.com/2.5.1/build/yahoo-dom-event/yahoo-dom-event.js"></script>
<script type="text/javascript" src="http://yui.yahooapis.com/2.5.1/build/logger/logger-min.js"></script>
...
</head>
Alternatively, you can copy the necessary files to your widget bundle and serve them locally on your device when the widget is running:
Please familiarize yourself with the YUI licensing terms.
Use the logger in your JavaScript (or HTML)
Please check YUI Logger Control documentation for more instructions. The sample code below just creates a container for the Logger Control on the HTML page and allows logging a hard coded word to the screen.
window.onload = init;
var myLogReader;
var myConfigs = {
width: "230px",
height: "30em",
newestOnTop: true,
footerEnabled: false
};
// Initializes the widget
function init() {
var myContainer = document.body.appendChild(document.createElement("div"));
myLogReader = new YAHOO.widget.LogReader(myContainer);
}
function logMsg() {
YAHOO.log("hello there");
}
The full source of the HTML using the JavaScript above is:
