另请注意,您需要实际加载cufon字体。使用Fabric.js时没有默认字体。
<script src="fabric.js"></script>
<script src="cufon.calibri.js"></script>
提供了很多字体
这是作者正计划取消对cufon的需求。这里讨论:Fabric.js + Google Fonts
如果您想渲染一个块,那么该块内部会有一些文本。我会做这样的事情。
//Render the block
var block = canvas.add(new fabric.Rect({
left: 100,
top: 100,
fill: 'blue'
}));
//Render the text after the block (so that it is in front of the block)
var text = canvas.add(new fabric.Text('I love fabricjs', {
left: block.left, //Take the block's position
top: block.top,
fill: 'white'
}));
//Render the text and block on the canvas
//This is to get the width and height of the text element
canvas.renderAll();
//Set the block to be the same width and height as the text with a bit of padding
block.set({ width: text.width + 15, height: text.height + 10 });
//Update the canvas to see the text and block positioned together,
//with the text neatly fitting inside the block
canvas.renderAll();

查看How to render text教程。
这很简单:
canvas.add(new fabric.Text('foo', {
fontFamily: 'Delicious_500',
left: 100,
top: 100
}));

另外值得注意的是,您可能需要调整Cufon的offsetLeft以帮助正确定位文本。类似的东西:
Cufon.fonts[your-fontname-in-lowercase-here].offsetLeft = 120;
