//使用节点和事件模块
YUI（）。use（node，event，function（Y）{
var handleClick = function（e）{
var docBody = Y.one（＃doc-body）; //相当于原型和jQuery中的$（元素）
var winHeight = docBody.get（'winHeight'）; viewportwidth
var winWidth = docBody.get（'winWidth'）; //获得viewport宽度
var red = parseInt（e.pageX *（255 / winWidth））;
var green = parseInt（e.pageY *（255 / winHeight））;
var blue = parseInt（red * green * 0.004）;
var bgstyle =rgb（+ red +，+ green + ;+ blue +）;
console.log（＃background-color：+ bgstyle +for＃doc-body）;
docBody.setStyle（background-color，bgstyle ）; //与原型和jQuery（元素）.css（）中的$（element）.setStyle（）相同
Y.one（＃rgbvalues）.set（innerHTML，bgstyle）; // set innerHTML
};
Y.on（mousemove，handleClick，＃doc-body）;
}）;

该脚本在FF5或Opera中无效，但在Chrome中运行良好。在萤火虫控制台上也没有错误。即使我从mousemove改变事件点击它是行不通的。
要解决您的问题，请添加此CSS：
html，body {
margin：0;
padding：0;
height：100％
}
html 和 body 元素在默认情况下并不占用100％的高度。
因为浏览器之间的不一致行为可能与您的页面使用怪癖模式有关，因为你没有文档类型。添加这个作为第一行：
<！DOCTYPE html>
I have a very simple YUI3 script which changes background of a web page. Here is the source
<html>
<head>
<title>YUI 3 events do not work!</title>
</head>
<body id="doc-body">
<div id="rgbvalues"> </div>
<script src="http://yui.yahooapis.com/3.3.0/build/yui/yui-min.js" charset="utf-8"></script>
<script type="text/javascript">
//use node and event modules
YUI().use("node", "event", function(Y){
var handleClick = function(e) {
var docBody = Y.one("#doc-body"); //equivalent to $(element) in prototype and jQuery(element)
var winHeight = docBody.get('winHeight');//get "viewport" height
var winWidth = docBody.get('winWidth');//get "viewport" width
var red = parseInt (e.pageX * (255/winWidth));
var green = parseInt(e.pageY * (255/winHeight));
var blue = parseInt (red*green*0.004);
var bgstyle = "rgb("+red+","+green+"," +blue+")";
console.log("setting background-color:"+bgstyle+" for #doc-body");
docBody.setStyle("background-color", bgstyle);//same as $(element).setStyle() from prototype and jQuery(element).css()
Y.one("#rgbvalues").set("innerHTML", bgstyle);//set innerHTML
};
Y.on("mousemove", handleClick, "#doc-body");
});
</script>
</body>
</html>
The script doesn't work in FF5 or Opera but works well in Chrome. There is no error on firebug console either. Even if I change the event from mousemove to click it doesn't work.
To fix your problem, add this CSS:
html, body {
margin: 0;
padding: 0;
height: 100%
}
The html and body elements do not take up 100% height by default.
The reason for the inconsistent behaviour between browsers is probably to do with the fact that your page is using Quirks Mode, because you don't have a doctype. Add this as the very first line:
<!DOCTYPE html>
