使用mapboxgl，我添加了一个自定义的 map 控件，可以做一些特殊的功能，基本功能引用了office例子。但是当我完成代码时，我发现按钮事件点击不起作用。我已经添加了 stopPropagation 函数。那么如何在mapbox控件中添加点击事件呢？
mapboxgl.accessToken = 'pk.eyJ1IjoieGlhb2thbmciLCJhIjoiY2lqc2d2NXlyMGhkbHU0bTVtcGNiOWxseCJ9.J5qsX13KKNT1slMGS-MOLg';
var map = new mapboxgl.Map({
container: 'map', // container id
style: 'mapbox://styles/mapbox/streets-v9', // stylesheet location
center: [-74.50, 40], // starting position [lng, lat]
zoom: 9 // starting zoom
});
class ToggleControl {
onAdd(map){
this.map = map;
this.container = document.createElement('div');
this.container.className = 'my-custom-control';
const button = this._createButton('monitor_button')
this.container.appendChild(button);
return this.container;
}
onRemove(){
this.container.parentNode.removeChild(this.container);
this.map = undefined;
}
_createButton(className) {
const el = window.document.createElement('button')
el.className = className;
el.textContent = 'toggleControl';
el.addEventListener('click',(e)=>{
e.style.display = 'none'
console.log(e);
// e.preventDefault()
e.stopPropagation()
},false )
return el;
}
}
const toggleControl = new ToggleControl()
map.addControl(toggleControl,'top-left')<!DOCTYPE html>

问题是 mapbox 容器定位样式删除了鼠标事件处理(pointer-events: none;):
.mapboxgl-ctrl-top-left,
.mapboxgl-ctrl-top-right,
.mapboxgl-ctrl-bottom-left,
.mapboxgl-ctrl-bottom-right {
position: absolute;
pointer-events: none;
z-index: 2;
}
因此您需要将类 mapboxgl-ctrl ( pointer-events: auto; ) 添加到容器中以捕获事件:
this.container.className = 'mapboxgl-ctrl my-custom-control';
或者手动设置这个 CSS 属性:
.my-custom-control {
pointer-events: auto;
}
