我希望通过单击按钮来缩放文本层。
var messageLayer = new Kinetic.Layer();
function writeMessage(message, xx, yy) {
var context = messageLayer.getContext();
context.font = '12pt Calibri';
context.fillStyle = 'white';
wrapText(context, message, xx, yy, seat_size, seat_size);
}
stage.add(messageLayer);
writeMessage(text, xx, yy);
document.getElementById('zoomInBtn').onclick = function zoomInStage(){
stage.setScale(2);
stage.draw();
}
我不知道为什么,但这似乎不起作用..
感谢您的帮助。
嗨,感谢您指出我的错误。但是在我添加 y 值之后,这仍然无法正常工作....
以下是我的代码:
enter <!DOCTYPE HTML>
<html>
<body>
<div id="container"></div>
<button id="scaleme" style="margin-left:10px;">Scale</button>
<script src="http://www.html5canvastutorials.com/libraries/kinetic-v4.3.0-beta2.js"></script>
<script>
function writeMessage(messageLayer, message) {
var context = messageLayer.getContext();
messageLayer.clear();
context.font = '18pt Calibri';
context.fillStyle = 'black';
context.fillText(message, 10, 25);
}
var stage = new Kinetic.Stage({
container: 'container',
width: 578,
height: 200
});
var messageLayer = new Kinetic.Layer();
stage.add(messageLayer);
writeMessage(messageLayer, 'text text text');
document.getElementById('scaleme').onclick = function scale(){
messageLayer.setScale(2,2);
}
</script>
</body>
</html>
请helppp....谢谢!
