ue5上调试js

一、UE4显示Echart图表

二、UE调用JS（修改Echart图表数据）

三、JS调用UE（UE4中打印js传递过来的数据）

一、UE4显示Echart图表

步骤：

1.下载WEBUI插件

我的UE编辑器版本是4.24.3对应版本的插件下载地址是

webui 插件：链接：https://pan.baidu.com/s/1vaZiqre8K2GEueVJOtZ2fA?pwd=xsby
提取码：xsby

下载后解压放到Plugins文件夹中

2.在Echart上下载一个例子

我下载的例子的链接：

Examples - Apache ECharts

点击下载示例

3.下载的HTML文件放到Content 或其子文件夹内：

4. 修改该HTML代码：
