javascript - jQCloud 不生成任何元素

我刚刚使用 Bower 和以下命令在我的项目中添加了 jQCloud2 库

bower install jqcloud2 --save

jQCloud - http://mistic100.github.io/jQCloud/demo.html

在头部添加了 css 和 javascript 文件

下面是我正在使用的一小段代码

<div id="cloud">
</div>
<script>
$(function(){
  var words = [
  {text: "Lorem", weight: 13},
  {text: "Ipsum", weight: 10.5},
  {text: "Dolor", weight: 9.4},
  {text: "Sit", weight: 8},
  {text: "Amet", weight: 6.2},
  {text: "Consectetur", weight: 5},
  {text: "Adipiscing", weight: 5}
];

$('#cloud').jQCloud(words);
});
</script>

我正在使用的库

  1. jQuery - 1.11.3
  2. jQuery-UI - 1.11.3
  3. Bootstrap - 3.3.5
  4. jQCloud2 - 2.0.1

我没有看到通过 jQCloud 库生成任何代码，是我做错了什么吗？感谢您的帮助

最佳答案 

$(document).ready(function($) {
  var words = [{
    text: "Lorem",
    weight: 13
  }, {
    text: "Ipsum",
    weight: 10.5
  }, {
    text: "Dolor",
    weight: 9.4
  }, {
    text: "Sit",
    weight: 8
  }, {
    text: "Amet",
    weight: 6.2
  }, {
    text: "Consectetur",
    weight: 5
  }, {
    text: "Adipiscing",
    weight: 5
  }];

  var some_words_with_same_weight =
    $("#jqcloud").jQCloud(words, {
      width: 500,
      height: 350
    });

});

您只需要宽度和高度。
