我有一个非常简单的paper.js脚本的奇怪情况。如果我不移动鼠标,则5秒后脚本将不会绘制文本。一旦我移动,它就会被显示出来。有人可以向我解释这种奇怪的行为吗?

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Simplify</title>
    <script type="text/javascript" src="http://paperjs.org/assets/js/paper.js"></script>    
    <script type="text/paperscript" canvas="canvas">
        setTimeout(function () {
            var textItem = new PointText({
                content: 'Click and drag to draw a line.',
                point: new Point(20, 30),
                fillColor: 'black',
            });
        }, 5000);
    </script>
</head>
<body>
    <canvas id="canvas" resize></canvas>    
</body>
</html>

您是否尝试过添加paper.view.draw();到你的功能结束?

setTimeout(function () {
        var textItem = new PointText({
            content: 'Click and drag to draw a line.',
            point: new Point(20, 30),
            fillColor: 'black',
        });
     view.draw();
    }, 5000);
