文字省略

提示

如果是在x轴上的,就在x轴上添加triggerEvent: true,如果是y轴就在y轴添加,我是在y轴上添加的
echarts的横向柱状图文字省略,鼠标移入显示内容 vue3,echarts,javascript,vue
并且自定义的方法(我取名为
extension

// echarts 横向省略文字 鼠标移入显示内容
export const extension = chart => {
	// 注意这里,是以y轴显示内容过长为例,如果是x轴的话,需要把params.componentType == 'yAxis'改为xAxis
	// 判断是否创建过div框,如果创建过就不再创建了
	// 该div用来盛放文本显示内容的,方便对其悬浮位置进行处理
	let elementDiv = document.getElementById("extension");
	if (!elementDiv) {
		let div = document.createElement("div");
		div.setAttribute("id", "extension");
		div.style.display = "block";
		document.querySelector("html").appendChild(div);
	}
	chart.on("mouseover", function (params) {
		console.log(params, "鼠标移入");

		if (params.componentType == "yAxis") {
			let elementDiv = document.querySelector("#extension");
			//设置悬浮文本的位置以及样式
			let elementStyle =
				"position: absolute;z-index: 99999;color: #fff;font-size: 12px;padding: 5px;display: inline;border-radius: 4px;background-color: #303133;box-shadow: rgba(0, 0, 0, 0.3) 2px 2px 8px";
			elementDiv.style.cssText = elementStyle;
			elementDiv.innerHTML = params.value;
			document.querySelector("html").onmousemove = function (event) {
				let elementDiv = document.querySelector("#extension");
				let xx = event.pageX - 10;
				let yy = event.pageY + 15;
				console.log("22", xx);
				elementDiv.style.top = yy + "px";
				elementDiv.style.left = xx + "px";
			};
		}
	});
	chart.on("mouseout", function (params) {
		//注意这里,我是以y轴显示内容过长为例,如果是x轴的话,需要改为xAxis
		if (params.componentType == "yAxis") {
			let elementDiv = document.querySelector("#extension");

			elementDiv.style.cssText = "display:none";
		}
	});
};
