vue 双y轴echarts x轴显示省略号 鼠标滑入显示提示窗
需求：鼠标移入x轴显示全部文字并且是悬浮窗的形式
效果图
上代码 cv直接用
html代码
js代码
悬浮窗核心代码
reminder(myChart) {
// params.componentType == 'xAxis'或者 params.componentType == 'yAxis' 看你需求是x还是y
// 显示悬浮窗 获取div 有就不创建没有创建
var divData = document.getElementById("extensionId");
if (!divData) {
var div = document.createElement("div");
div.setAttribute("id", "extensionId");
div.style.display = "block";
document.querySelector("html").appendChild(div);
}
// 鼠标移入事件
myChart.on("mouseover", function(params) {
if (params.componentType == "xAxis") {
var divData = document.querySelector("#extensionId");
//显示的样式 自己写就行
var elementStyle =
"position: absolute;z-index: 99999;color: #000;font-size: 12px;padding: 5px;display: inline;border-radius: 4px;background-color: #fff;box-shadow: rgba(0, 0, 0, 0.3) 2px 2px 8px;border:1px solid #000";
divData.style.cssText = elementStyle;
divData.innerHTML = params.value;
document.querySelector("html").onmousemove = function(event) {
var divData = document.querySelector("#extensionId");
var xx = event.pageX + 40; //x位置 自己调整
var yy = event.pageY - 20; //y位置 自己调整
divData.style.top = yy + "px";
divData.style.left = xx + "px";
};
}
});
// 鼠标移出事件
myChart.on("mouseout", function(params) {
if (params.componentType == "xAxis") {
var divData = document.querySelector("#extensionId");
divData.style.cssText = "display:none";
}
});
},柱状图核心代码
在下面得到echarts之后 传入这个方法 当然也可以写到一起
