我使用html2canvas转换画布上的div.像这样:
<script src="js/libs/jquery-1.7.1.min.js"></script>
<script src="js/libs/jquery-ui-1.8.17.custom.min.js"></script>
<script src="js/html2canvas/html2canvas.js"></script>
...
<body id="body">
<div id="demo">
...
</div>
</body>
<script>
$('#demo').html2canvas({
onrendered: function( canvas ) {
var img = canvas.toDataURL()
window.open(img);
}
});
</script>
我收到此错误:html2canvas.js中的"未捕获错误:IndexSizeError:DOM异常1":
ctx.drawImage( canvas, bounds.left, bounds.top, bounds.width, bounds.height, 0, 0, bounds.width, bounds.height );
有没有人知道发生了什么？
