我是JSNetworkX的新手。我使用jsnetworkx.org中的示例创建了一个图表，但我只能记录它，我无法显示它。
所以这是<?php
namespace App\Http\Controllers;
use Request;
use Auth;
use Sentinel;
use App\Feed;
use App\Http\Requests;
use App\Blog;
use App\Http\Controllers\Controller;
use App\Comment;
class FeedsController extends Controller
{
public function index() {
// $comments = Comment::latest()->get();
$feeds = Feed::with('comments', 'user')->where('user_id', Sentinel::getUser()->id)->latest()->get();
$blogs = Blog::latest()->simplePaginate(5);
$blogs->setPath('blog');
return view('action.index', compact('feeds', 'blogs'));
}
public function store(Requests\CreateFeedRequest $request)
{
$request->merge( [ 'user_id' => Sentinel::getuser()->id] );
Feed::create($request->all());
return redirect('home');
}
public function storecomment(Requests\CommentRequest $request, Feed $feed)
{
$comment = new Comment;
$comment->user_id =Sentinel::getuser()->id;
$comment->feed_id = $request->feed_id;
$comment->comment = $request->comment;
$comment->save();
return redirect('/home');
}
}
文件：
index.html这是用<html>
<head>
<script src="https://d3js.org/d3.v4.js"></script>
<script src="jsnetworkx.js"></script>
</head>
<body>
<script src = "script.js"></script>
</body>
</html>
编写的代码：
script.js这是输出： [0,1,2,3,4,5]
这是我得到的错误：
JSNetworkX错误 - TypeError：undefined不是对象（评估＆＃39; M.layout.force＆＃39;）
答案 0 :(得分：0)
问题包括最新版本的D3.js.
更改
<script src="https://d3js.org/d3.v4.js"></script>
到
<script src="https://d3js.org/d3.v3.js"></script>
会修复它。
