UE5.1 利用WEBUI插件完成UE与JS的交互（UE5.1嵌入WEB）

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：

修改该HTML代码：

    var dom = document.getElementById('container');
    var myChart = echarts.init(dom, null, {
      renderer: 'canvas',
      useDirtyRect: false
    });
    var app = {};
    
    var option;

    option = {
  xAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  yAxis: {

  series: [

      data: [120, 200, 150, 80, 70, 110, 130],

      showBackground: true,
      backgroundStyle: {
        color: 'rgba(180, 180, 180, 0.2)'
      }
    }
  ]
};

    if (option && typeof option === 'object') {
      myChart.setOption(option);
    }

    ue.interface.ue2js = function(ueData){
      var jsonObj = JSON.parse(ueData);
      myChart.setOption(jsonObj);
    };

    window.addEventListener('resize', myChart.resize);
