[GitHub] [echarts] JinJianQi opened a new issue, #17638: [Feature] How can I dispatch a wheel event programmatically?
JinJianQi opened a new issue, #17638:
URL: https://github.com/apache/echarts/issues/17638
### What problem does this feature solve?
I just have two Echart instances, both of them have a dataZoom. How do I make them move synchronously when I scroll?
### What does the proposed API look like?
Maybe just offer a dispatch function that I can pass a event that type is wheel.

Can you first make a demo (without zrender changes) to show what the problem is and then I can help check if this change is necessary?

@Ovilia Hello~, Thanks for reply, there is a demo to show that, I just want fake the wheel event on another div.
this is a simple demo:
<img width="702" alt="image" src="https://user-images.githubusercontent.com/33452468/191306445-164d9582-137e-4da3-8460-9616e19fb34a.png">
```
var dom = document.getElementById("chart-container");
var myChart = echarts.init(dom, null, {
renderer: "canvas",
useDirtyRect: false
});
var app = {};
var option;
option = {
xAxis: {},
yAxis: {},
dataZoom: [
{
type: "slider"
},
{
type: "inside"
}
],
series: [
{
type: "line",
data: [
[0, 0],
[1, 1],
[2, 2],
[6, 10]
]
}
]
};
let wrapper = document.createElement("div");
wrapper.innerText = "wheel on me";
wrapper.style.height = "300px";
wrapper.style.width = "300px";
wrapper.style.position = "fixed";
wrapper.style.backgroundColor = "rgba(0,0,0,.3)";
wrapper.style.top = "0px";
wrapper.style.left = "0px";
document.body.appendChild(wrapper);
const onWheel = (e) => {
console.log("onWheel");
const fakeWheel = new WheelEvent("wheel", e);
fakeWheel.zrX = e.offsetX;
fakeWheel.zrY = e.offsetY;
console.log(fakeWheel);
myChart.getZr().handler.proxy.dom.dispatchEvent(fakeWheel);
};
wrapper.addEventListener("wheel", onWheel);
if (option && typeof option === "object") {
myChart.setOption(option);
}
window.addEventListener("resize", myChart.resize);
```

I'm not sure it works with [connect](https://echarts.apache.org/en/api.html#echarts.connect). You can have a try.

I have to use two instances, because I need to set some styles on each one. Something like border style.
