Below I will share with you an example of using vue combined with Echarts to achieve click highlighting effect. It has a good reference value and I hope it will be helpful to everyone.

This article mainly introduces how to use Echarts in vue to achieve click highlighting effect.

1. First, take a look at the introduction on the official website:

http://echarts.baidu.com/api.html#action .graph.focusNodeAdjacency

2. Bind these two events during initialization. The events that need to be bound are mouse click events and right-click events.

mounted: function () {
  let that = this;
  let myChart = this.$echarts.init(document.getElementById(&#39;myChart&#39;));
  myChart.on(&#39;click&#39;, function (params) {
  console.log(params);
  //点击高亮
  that.myChart.dispatchAction({
   type: &#39;focusNodeAdjacency&#39;,
   // 使用 dataIndex 来定位节点。
   dataIndex: params.dataIndex
  });
  if (params.dataType == &#39;edge&#39;) {
   that.handleClick(params);
  } else if (params.dataType == &#39;node&#39;) {
   if (that.firstNode == &#39;&#39;) {
   that.firstNode = params.name;
   } else {
   that.secondNode = params.name;
   }
  }
  });
  //取消右键的弹出菜单
  document.oncontextmenu = function () {
  return false;
  };
  //右键取消高亮
  myChart.on(&#39;contextmenu&#39;, function (params) {
  console.log(params);
  that.myChart.dispatchAction({
   type: &#39;unfocusNodeAdjacency&#39;,
   // 使用 seriesId 或 seriesIndex 或 seriesName 来定位 series.
   seriesIndex: params.seriesIndex,
  })
  });
  that.myChart = myChart;
  that.drawLine();
 },

Copy after login
