更新時(shí)間：2024年01月30日 09:26:11 作者：左小白

找到一個(gè)好用的vue樹形穿梭框組件都很難,又不想僅僅因?yàn)橐粋€(gè)穿梭框在element-ui之外其他重量級(jí)插件,本文給大家分享vue3+Element Plus實(shí)現(xiàn)自定義穿梭框的示例代碼,感興趣的朋友一起看看吧

先上效果圖：具體細(xì)節(jié)可以自己調(diào)整這里主要說(shuō)明派單，取消這兩個(gè)按鈕的實(shí)現(xiàn)

DOM部分代碼：

穿梭框的table表頭是動(dòng)態(tài)的html中無(wú)需修改，使用這個(gè)組件首先需要在scripe中創(chuàng)建如下變量

const tableData = ref([]) //左側(cè)數(shù)據(jù)
const selectedLeft = ref([])// 左側(cè)選中數(shù)據(jù)
const sharedData = ref([])//右側(cè)數(shù)據(jù)
const selectedRight = ref([])// 右側(cè)選中數(shù)據(jù)
//表格loading
const flagTbale = ref(false) //可以去除所有的flagTbale 變量即可去除loading功能
//兩個(gè)table表頭
const cols = ref([
    { id: 1, prop: 'latnName', label: '本地網(wǎng)' },
    { id: 2, prop: 'orgId', label: '組織編碼' },
    { id: 3, prop: 'orgName', label: '組織' },
])

然后就是最重要的按鈕功能

// 取消按鈕
const buttonLeft = async () => {
    if (!selectedRight.value || !Array.isArray(selectedRight.value)) {
        selectedRight.value = [];
    }
    // 將右側(cè)選中的數(shù)據(jù)移動(dòng)到左側(cè)
    tableData.value = tableData.value.concat(selectedRight.value);
    // 從右側(cè)數(shù)據(jù)中移除已經(jīng)移動(dòng)的數(shù)據(jù)
    sharedData.value = sharedData.value.filter(item => !selectedRight.value.includes(item));
    // 清空右側(cè)選中的數(shù)據(jù)
    selectedRight.value = [];
}
// 分享按鈕
const buttonRight = async () => {
    if (!selectedLeft.value || !Array.isArray(selectedLeft.value)) {
        selectedLeft.value = [];
    }
    // 將左側(cè)選中的數(shù)據(jù)移動(dòng)到右側(cè)
    sharedData.value = sharedData.value.concat(selectedLeft.value);
    // 從左側(cè)數(shù)據(jù)中移除已經(jīng)移動(dòng)的數(shù)據(jù)
    tableData.value = tableData.value.filter(item => !selectedLeft.value.includes(item));
    // 清空左側(cè)選中的數(shù)據(jù)
    selectedLeft.value = [];
}

按鈕禁用邏輯實(shí)現(xiàn)

// 按鈕是否禁用
const qxfxDisabled = ref(true)
const fxDisabled = ref(true)
// 左側(cè)表格選中事件
const handleLeftSelectionChange = (selection) => {
    if (selection.length !== 0) {
        fxDisabled.value = false
    }
    if (selection.length === 0) {
        fxDisabled.value = true
    }
};
// 右側(cè)表格選中事件
const handleRightSelectionChange = (selection) => {
    selectedRight.value = selection;
    if (selection.length !== 0) {
        qxfxDisabled.value = false
    }
    if (selection.length === 0) {
        qxfxDisabled.value = true
    }
};

到這里你就可以使用在這個(gè)組件了。這是經(jīng)過插分的代碼原本還擁有表頭切換的邏輯如有需要可留言.我后續(xù)可以在做整理
