TypeError：d3.layout.cloud不是一个函数 [英] TypeError: d3.layout.cloud is not a function
问题描述
我要从这里复制程式码。我的代码本质上与示例代码相同，除非我在我的服务器上运行d3.layout.cloud.js。当我运行它我得到一个类型错误d3.layout.cloud不是一个函数。这可能是什么原因？
I am copying code from here. My code is essentially identical to the example code except I am running d3.layout.cloud.js on my server. When I run it I am getting a type error that d3.layout.cloud is not a function. What could be the reasons for this?
<!DOCTYPE html>
<meta charset="utf-8">
<script src="../lib/d3/d3.js"></script>
<script src="../d3.layout.cloud.js"></script>
<body>
<script>
var fill = d3.scale.category20();
d3.layout.cloud().size([300, 300])
.words([
"Hello", "world", "normally", "you", "want", "more", "words",
"than", "this"].map(function(d) {
return {text: d, size: 10 + Math.random() * 90};
}))
.rotate(function() { return ~~(Math.random() * 2) * 90; })
.font("Impact")
.fontSize(function(d) { return d.size; })
.on("end", draw)
.start();
function draw(words) {
d3.select("body").append("svg")
.attr("width", 300)
.attr("height", 300)
.append("g")
.attr("transform", "translate(150,150)")
.selectAll("text")
.data(words)
.enter().append("text")
.style("font-size", function(d) { return d.size + "px"; })
.style("font-family", "Impact")
.style("fill", function(d, i) { return fill(i); })
.attr("text-anchor", "middle")
.attr("transform", function(d) {
return "translate(" + [d.x, d.y] + ")rotate(" + d.rotate + ")";
})
.text(function(d) { return d.text; });
}
</script>
推荐答案
您确定放了d3.cloud。 layout.js在您的服务器上的正确文件夹中？
Are you sure you've put d3.cloud.layout.js in the correct folder on your server?
我编辑您的代码以指向存在的文件：
I edited your code to point to files that do exist:
<script src="http://d3js.org/d3.v3.min.js"></script>
<script src="https://gist.github.com/emeeks/3361332/raw/61cf57523fe8cf314333e5f60cc266351fec2017/d3.layout.cloud.js"></script>
似乎工作正常：
要查看是否会导致您的问题，请使用chrome（ctrl-shift-j）打开控制台，看看是否有任何无法加载资源错误。
To see if this is causing your problem, open the console in chrome (ctrl-shift-j) and see if there are any "Failed to load resource" errors.
