Konva 内容重叠无法触发点击事件的解决方法
写在前面:
- 环境:Vue3 + Konva + vite
- 在绘制界面时踩坑,主要是关于 listening 属性的使用
-
在绘制界面时,不免出现有内容重叠的情况,这会影响事件的触发
-
使用设置
listening
属性可以允许事件穿透,默认为true
不可穿透(示例如下)<template> <div> <div id="mybtn"></div> </div> </template> <script> import Konva from 'konva'; export default { data() { return { position: { posX: 0, posY: 0, }, size: { width: 100, height: 50, }, styles: { borderSize: 1, fontSize: 12, backgroundColor: '', fontColor: '#000', borderColor: '#000', opacity: 1, }, btnText: 'Button', }; }, mounted() { this.initializeKonva(); }, methods: { initializeKonva() { const stage = new Konva.Stage({ container: 'mybtn', width: this.size.width, height: this.size.height, }); const layer = new Konva.Layer(); stage.add(layer); const button = new Konva.Rect({ x: this.position.posX, y: this.position.posY, width: this.size.width, height: this.size.height, fill: this.styles.backgroundColor, stroke: this.styles.borderColor, strokeWidth: this.styles.borderSize, opacity: this.styles.opacity, }); const buttonText = new Konva.Text({ x: this.position.posX, y: this.position.posY, width: this.size.width, height: this.size.height, text: this.btnText, fontSize: this.styles.fontSize, fontFamily: 'Arial', fill: this.styles.fontColor, align: 'center', verticalAlign: 'middle', listening: false, // 设置listening为false,允许事件穿透 }); button.on('click', this.clickBtn); layer.add(button); layer.add(buttonText); layer.draw(); }, clickBtn() { console.log('clickBtn run'); // 点击事件逻辑 } }, }; </script> <style scoped> div { width: 100%; height: 100%; } </style>
