我是JavaScript和Django的新手。我必须使用D3js动画制作svg文件，以便练习并理解其工作原理我决定将the miserables widget添加到我的本地Django网站。我有一个简单的观点：d3js返回“[object％20Object]”和“Uncaught TypeError：无法读取属性：未定义的节点”
def miserable(request):
return render_to_response('index.html')
的网址是： url(r'^moremiser/$','more_miserable')和我都抄index.html，然后miserable.json到我的模板文件夹。当我转到应该显示小部件的网址时，我所得到的只是一个空白屏幕。我究竟做错了什么？设置本地网站的人安装了tinymce和压缩机，是否会造成问题？ 这里是index.html和miserables.json的代码。他们都是在我的模板文件夹：
#index.html
<!DOCTYPE html>
<meta charset="utf-8">
<style>
.node {
stroke: #fff;
stroke-width: 1.5px;
}
.link {
stroke: #999;
stroke-opacity: .6;
}
</style>
<body>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script>
var width = 960,
height = 500;
var color = d3.scale.category20();
var force = d3.layout.force()
.charge(-120)
.linkDistance(30)
.size([width, height]);
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height);
d3.json("miserables.json", function(error, graph) {
force
.nodes(graph.nodes)
.links(graph.links)
.start();
var link = svg.selectAll(".link")
.data(graph.links)
.enter().append("line")
.attr("class", "link")
.style("stroke-width", function(d) { return Math.sqrt(d.value); });
var node = svg.selectAll(".node")
.data(graph.nodes)
.enter().append("circle")
.attr("class", "node")
.attr("r", 5)
.style("fill", function(d) { return color(d.group); })
.call(force.drag);
node.append("title")
.text(function(d) { return d.name; });
force.on("tick", function() {
link.attr("x1", function(d) { return d.source.x; })
.attr("y1", function(d) { return d.source.y; })
.attr("x2", function(d) { return d.target.x; })
.attr("y2", function(d) { return d.target.y; });
node.attr("cx", function(d) { return d.x; })
.attr("cy", function(d) { return d.y; });

当我打开谷歌浏览器JavaScript调试器，我看到的不是去URL“moremiser”服务器尝试去“moremiser/[对象％20Object ]，然后出现另一个错误消息：“”Uncaught TypeError：无法读取属性：未定义的节点“。我应该修改什么？
是响应200的状态吗？ – Willian 2013-03-01 16:29:57
不，我只是检查了Bash，它是404。此外，我打开代码查看器（Google Chrome中的F12）和Frames /（127.0.0.1）/ Scripts中，我看到“Uncaught TypeError：无法读取属性”节点“未定义”。 – 2013-03-01 16:39:12
我该怎么办？ – 2013-03-01 16:46:07
