handsontable/vue3 不通过右键进行,通过点击ref实现右键所有功能

可以通过使用 `contextmenu` 事件来模拟右键菜单的行为。首先,在需要触发右键菜单的元素上添加一个 `ref`,然后在组件中监听 `contextmenu` 事件,阻止默认行为并计算出鼠标点击位置,最后根据点击位置和需要显示的菜单项来显示右键菜单。
下面是一个示例代码:
```html
<template>
<div ref="container" @contextmenu.prevent="showContextMenu">
<table>
<thead>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr v-for="(person, index) in people" :key="index">
<td>{{ person.name }}</td>
<td>{{ person.age }}</td>
</tr>
</tbody>
</table>
<div ref="contextMenu" class="context-menu" :style="{ top: contextMenuTop + 'px', left: contextMenuLeft + 'px' }">
<ul>
<li @click="editCell">Edit Cell</li>
<li @click="deleteRow">Delete Row</li>
</ul>
</div>
</div>
</template>
<script>
import { ref } from 'vue';
import Handsontable from 'handsontable';
export default {
setup() {
const containerRef = ref(null);
const contextMenuRef = ref(null);
const contextMenuTop = ref(0);
const contextMenuLeft = ref(0);
const people = [
{ name: 'Alice', age: 20 },
{ name: 'Bob', age: 30 },
{ name: 'Charlie', age: 25 },
];
function showContextMenu(event) {
event.preventDefault();
const container = containerRef.value;
const contextMenu = contextMenuRef.value;
if (!container || !contextMenu) {
return;
}
const x = event.clientX - container.offsetLeft;
const y = event.clientY - container.offsetTop;
contextMenuTop.value = y;
contextMenuLeft.value = x;
contextMenu.style.display = 'block';
}
function editCell() {
const hot = Handsontable.getSingleton();
const selected = hot.getSelected();
const [row, col] = selected[0];
const cell = hot.getCell(row, col);
cell.focus();
}
function deleteRow() {
const hot = Handsontable.getSingleton();
const selected = hot.getSelected();
const [row, _] = selected[0];
hot.alter('remove_row', row);
}
return {
containerRef,
contextMenuRef,
contextMenuTop,
contextMenuLeft,
people,
showContextMenu,
editCell,
deleteRow,
};
},
mounted() {
const container = this.containerRef;
const contextMenu = this.contextMenuRef;
if (!container || !contextMenu) {
return;
}
container.addEventListener('click', () => {
contextMenu.style.display = 'none';
});
contextMenu.addEventListener('click', () => {
contextMenu.style.display = 'none';
});
}
};
</script>
<style scoped>
.context-menu {
position: absolute;
display: none;
z-index: 1;
}
.context-menu ul {
list-style: none;
margin: 0;
padding: 0;
background-color: #fff;
border: 1px solid #ccc;
box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.3);
}
.context-menu li {
padding: 8px 12px;
cursor: pointer;
}
.context-menu li:hover {
background-color: #f7f7f7;
}
</style>
```
在上述代码中,我们使用 `ref` 分别引用了包含表格和右键菜单的容器元素和右键菜单元素。在容器元素上监听 `contextmenu` 事件,阻止默认行为并计算出鼠标点击位置,然后根据位置计算出右键菜单应该出现的位置。`editCell` 和 `deleteRow` 分别是右键菜单中的两个操作,它们可以通过 Handsontable 的 API 来实现。最后,我们在组件的 `mounted` 钩子中监听容器和右键菜单的点击事件,以便在点击其他地方时隐藏右键菜单。
