Pat*_* S. 4 html css google-visualization responsive-design
我对 HTML、CSS 和 Javascript 比较陌生。我正在编写一个 JSP 应用程序(我是一名 Java 程序员)并且一直在学习响应式网页设计。我在让一些谷歌图表与响应式设计一起工作时遇到了麻烦。我在页面上并排放置了两个图表。
我什至用了一个例子来说明如何在 codepen 上获得响应式谷歌图表。当我在 codepen 的网站上使用它时,该示例有效。但是当我将它保存在我的电脑上并打开文件时,图表不再响应。这让我觉得不是代码本身有问题,而是我的浏览器有问题。任何帮助将不胜感激。
这是我的 JSP 应用程序的代码。HTML:
<div class="charts">
<div class="pieChartDiv">
<div id="piechart"></div>
</div>
<div class="lineChartDiv">
<div id="chart_div"></div>
</div>
</div>

页面截图和小页面截图:
第一个图表似乎不会调整大小。codepen 中的示例以相同的方式起作用。
代码笔示例:
https://codepen.io/flopreynat/pen/BfLkA
我可能会离开,所以请耐心等待。任何建议都会非常有帮助。
我相信这段代码可能是您的解决方案,如果窗口大小发生变化,它会调整图表的大小(“反应式响应”):
$(window).resize(function(){
ChartFunctionName();
});

我是初学者,但这是我发现并用来使我的 Google 图表具有响应性并且它有效的方法:仅供参考此示例页面,您可以在其中查看 Google 图表 -> 我使用的完整代码:
function TekenBasisschoolUitstroom()
{
var data = new google.visualization.arrayToDataTable([
['School', 'Speciaal-praktijk-kader', 'VMBO-kader', 'VMBO-T-voorheen MAVO', 'VMBO-T/HAVO', 'HAVO', 'HAVO/VWO',
'VWO'],
['De Ster', 1, 0, 0, 0, 3, 0, 1], ['OBS Driespan', 8, 3, 13, 1, 27, 0, 20] ]);
var schoolUitstroomOpties = {
