如何停止文字溢出宽度？

Question

我需要知道为什么我的文本总是overflow。 我想在overflow

时将其隐藏

var canvas = window._canvas = new fabric.Canvas('c1');

var text = new fabric.Text("Bharatasdsaasdasda\nnn\nklssd", {
    fontFamily: 'Courier New',
    left: 0,
    top: 0,
    fontSize: 16,
    fill: '#000000',
    scaleToWidth: 2.8
});

var rect = new fabric.Rect({
    width: 100,
    height: 100,
    fill: '#ffcc12',
});

var group = new fabric.Group([rect, text]);
canvas.add(group);
text.width = 10;
canvas.renderAll();
