我使用以下示例作为基础,并希望使其成为动态词云 https://github.com/jasondavies/d3-cloud

数据被添加到数组中,但我的word-cloud没有反映新添加的单词:

<script>
  var fill = d3.scale.category20();
  var data = [{word:"Hello",weight:20},{word:"World",weight:10},{word:"Normally",weight:25},{word:"You",weight:15},{word:"Want",weight:30},{word:"More",weight:12},{word:"Words",weight:8},{word:"But",weight:18},{word:"Who",weight:22},{word:"Cares",weight:27}];

  d3.layout.cloud().size([500, 500])
          .words(data.map(function(d) {
              return {text: d.word, size: d.weight};
          }))
          .padding(5)
         .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(" + …

我正在尝试将用户登录模块添加到 node.js 中的现有应用程序。它为每个模块使用单独的路由文件，并使用一个主路由文件来使用最终在 server.js 中使用的所有子路由。这是我的应用程序代码和结构：

app
    views
        user
            index.ejs
            login.ejs
            signup.ejs
            profile.ejs
    routes
        docs
            index.js
        user
            index.js
        index.js
    config
        passport.js

    server.js

服务器.js

const express = require('express')
    const app = express()
    const path = require('path')
    const bodyParser = require('body-parser')
    const cookieParser = require('cookie-parser')
    const passport = require('passport')
    const flash = require('connect-flash')
    const session = require('express-session')

    const routes = require('./routes/')

    const port = process.env.PORT || 3000;

    app.use(express.static(path.join(__dirname, 'public')));

    require('./config/passport')(passport);

    app.use(bodyParser.urlencoded({
        extended: true
    }));

    app.use(cookieParser());
    app.use(bodyParser.json());

    app.set('view engine', 'ejs');
    app.set('views', path.join(__dirname, 'views'));


    app.use(session({ …
