javascript – d3生成的SVG没有响应
作者：互联网
我正在尝试创建一个响应式SVG.我已经成功创建了一个示例SVG：
<html xmlns:xlink="http://www.w3.org/1999/xlink"><head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
</head>
<body>
<div id="container">
<svg viewBox="0 0 600 200" preserveAspectRatio="xMidYMid" id="chart">
<circle fill="red" cy="100" cx="100" r="100"></circle>
<circle fill="blue" cy="100" cx="300" r="100"></circle>
<circle fill="green" cy="100" cx="500" r="100"></circle>
</svg>
</div>
</body></html>

如果您在jsfiddle版本中调整面板边界,则可以看到圆圈的大小适当缩放.
我想用D3创建完全相同的SVG.
<html xmlns:xlink="http://www.w3.org/1999/xlink"><head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
<script type="text/javascript" src="http://d3js.org/d3.v3.js"></script>
</head>
<body>
<div id="container">
</div>
<script type="text/javascript">
var width=600, height=200;
var svg = d3.select("#container").append("svg")
.attr("id","chart")
.attr("preserveAspectRatio", "xMidYMid")
.attr("viewbox", "0 0 "+ width + " " + height);
svg.append("circle")
.attr("r","100")
.attr("cx","100")
.attr("cy","100")
.attr("fill","red");
svg.append("circle")
.attr("r","100")
.attr("cx","300")
.attr("cy","100")
.attr("fill","blue");
svg.append("circle")
.attr("r","100")
.attr("cx","500")
.attr("cy","100")
.attr("fill","green");
</script>
</body></html>

尽管我可以说,渲染的HTML完全相同,但第二个示例无法正常工作(请参阅jsfiddle).
奇怪的是,如果我使用浏览器的检查器来更改viewBox属性中的任何四个数字,行为会立即按预期工作.
思考？
解决方法:
viewBox有一个大写的B：
.attr("viewBox", "0 0 "+ width + " " + height);
