關(guān)于hichart多個(gè)圖表懸浮同時(shí)顯示tooltips框的問題

之前提問并沒有指出是什么所謂同源事件 故而現(xiàn)在更新一波

正文開始

其實(shí)也沒有什么難度，看了你的demo，無非是一些事件注冊(cè)，好消息是我剛才順手寫了個(gè)vue-highchart里使用的例子，先放效果給你看吧

其實(shí)，最重要的是你忘記框架或者庫的存在，一切從js的層面去看它
以下是你評(píng)論里貼的例子的截圖

可以看到就是獲取自身chart對(duì)象以及dom 然后得到其它c(diǎn)hart對(duì)象以及dom 然后開始事件注冊(cè)
所以vue里面我們也這樣做不就好了？

我的代碼（關(guān)鍵步驟里面有注釋）

<template>
    <div>
        <highcharts style="height:200px;width:500px;" :options="createOption(chartData.chart1)" ref="c1"></highcharts>
        <highcharts style="height:200px;width:500px;" :options="createOption(chartData.chart2)" ref="c2"></highcharts>
        <highcharts style="height:200px;width:500px;" :options="createOption(chartData.chart3)" ref="c3"></highcharts>
    </div>
</template>

你看看事件注冊(cè)部分是不是和你的那個(gè)代碼很像，沒錯(cuò)，我就是照著抄的。

offset是啥？

至于offset方法是啥？因?yàn)槲彝耆灰蕾囉趈query，所以自己實(shí)現(xiàn)了一個(gè)offset方法，基本也是照著jquery源碼抄著改的
也可以給你看一下offset的代碼

// offset: borrow ideas from the implement of offset in jQuery.fn.extend
export const offset = elem => {
    /* jshint eqeqeq: false */
    const isWindow = obj => obj != null && obj == obj.window;
    const getWindow = ele =>
        isWindow(ele)
            ? ele
            : ele.nodeType === 9 ? ele.defaultView || ele.parentWindow : false;

    let docElem,
        win,
        box = { top: 0, left: 0 },
        doc = elem && elem.ownerDocument;

    if (!doc) {
        return;
    }
    docElem = doc.documentElement;
    // Make sure it's not a disconnected DOM node
    if (!docElem.contains(elem)) {
        return box;
    }
    // If we don't have gBCR, just use 0,0 rather than error
    // BlackBerry 5, iOS 3 (original iPhone)
    if (typeof elem.getBoundingClientRect === "function") {
        box = elem.getBoundingClientRect();
    }
    win = getWindow(doc);
    return {
        top:
            box.top +
            (win.pageYOffset || docElem.scrollTop) -
            (docElem.clientTop || 0),
        left:
            box.left +
            (win.pageXOffset || docElem.scrollLeft) -
            (docElem.clientLeft || 0),
    };
};

其它注意事項(xiàng)

哦對(duì)了，我只抄了mousemove部分，其它部分你自己對(duì)著慢慢抄.
實(shí)際使用的時(shí)候，addEventListener里的function最好不要匿名，這樣方面組件beforeDestory的時(shí)候可以removeEventListener取消監(jiān)聽
