openlayers禁用鼠标滚轮放大、拖拽事件并设置为只有按住Ctrl键才可以执行放大拖拽操作

 禁用openlayers鼠标滚轮放大、拖拽移动地图设置这两行代码即可：

new Map({interactions: defaults({ dragPan: false, mouseWheelZoom: false }),
})

或者设置只允许按住Ctrl键才可以操作 

import { DragPan, MouseWheelZoom, defaults } from "ol/interaction.js";
import { platformModifierKeyOnly } from "ol/events/condition.js";const map = new Map({interactions: defaults({ dragPan: false, mouseWheelZoom: false }).extend([new DragPan({condition: function (event) {return (// 检查是否有两个触点，或者按下了ctrl键this.getPointerCount() === 2 || platformModifierKeyOnly(event));},}),new MouseWheelZoom({condition: platformModifierKeyOnly,}),]),layers: [new TileLayer({source: new OSM(),}),],target: "map",view: new View({center: [0, 0],zoom: 2,}),});

•  new MouseWheelZoom({ condition: platformModifierKeyOnly }) 用于创建一个鼠标滚轮缩放交互
• condition是一个配置项，用于指定触发缩放的条件。
• platformModifierKeyOnly是一个条件函数，仅在按住平台修饰键（如 Ctrl 键）时返回 true。
