在这个小提琴中，我试图展示一个包含高图的div：
http://jsfiddle.net/ot24zrkt/129/
此行应显示容器：$('#container' + $(this).val()).show();？
小提琴代码：
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/highcharts-more.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>
<select id="category_faq">
<option value="0">item1</option>
<option value="1">item2</option>
<!-- <option value="3">item3</option> -->
</select>
<div id="container1" style="width:500px;height:400px;margin:1.5em 1em;"></div>
<script>
var d = new Date();
var pointStart = d.getTime();

答案 0 :(得分：2)
更改选择后，您将隐藏任何div
$('#category_faq').on('change', function () {
$('div').hide(); //this hides every div
$('#container' + $(this).val()).show(); //with no divs, there's no place for this to render
});
删除此行：$('div').hide();

另外，你在jsFiddle中选择了jQuery 1.6。如果你使用的是1.6，它就不能使用highcharts。你需要（我认为）至少1.10。
答案 1 :(得分：0)
看看：http://jsfiddle.net/ot24zrkt/133/
HTML：
<select id="category_faq">
<option value="1">item1</option>
<option value="2">item2</option>
<!-- <option value="3">item3</option> -->
</select>
JS：
$('#category_faq').on('change', function () {
$('div[id^="container"]').hide();
$('#container' + $(this).val()).show();
});
首先，您至少需要JQuery 1.7.2才能使highcharts正常工作。
此外，如果您希望更改事件正常工作，则应隐藏div但不是全部，在这种情况下，您还将隐藏由highcharts生成的#highcharts-0 div。您可以改为使用$('div[id^="container"]')。
最后，#category_faq中的选项值应与相应的#container div的数量相同。在你的JSFiddle中，你有选项值设置为0和1（应该是1和2），而你的第一个容器有#container1 id。
