vue echarts tooltip使用动态模板

先上代码

					  tooltip: {
						  // 这里是车辆icon
						  show: true,
						// trigger: "item",
						// backgroundColor: "transparent",
						appendToBody: true,
						textStyle: {
						color: "#ffffff" //设置文字颜色
						},
						formatter: (params) => {
							return formatHtml(params.data)
						},
					  },

然后mounted(){}

mounted(){

			window.formatHtml = function(params){
				// 车辆弹窗
				const item = params.extraInfo.item;
			
				let carData = {};
				carData.stop_time = item.stopTime;
				carData.car_number = item.carNum;
				carData.vkey = item.vkey;
				carData.isConn = item.isConn == 1 ? '在线' : '离线';
				carData.ups = item.ups == 1 ? '电源正常' : '电源异常';
				carData.accStatus = item.accStatus == 1 ? '点火' : '熄火';
				carData.speed = item.speed + 'km/h';
				carData.dir = (item.dir);
				carData.live = '';
				// carData.car_token = car_token;
				carData.shareUrl = item.shareUrl ? item.shareUrl.replace("http://", "https://") : '';
				carData.userName = item.userName;
				carData.userPhone = item.userPhone;
				    return `
				    <div class='input-card content-window-card'>
				        <div class="showInfo">
				            <div class='input-item'>
