vue3+vxe-table实现可编辑、展开行(展开行内容为动态表格)

需求:为了支持运维的高效率工作,需要新增,编辑,归档事项,事项中又包括了task1,task2,task3......在任务项中又包括了要做的各种编辑项,新增项,先几个图来介绍下:

1.新增事项:通过弹窗填写新增的事项,其中包括了提交时做的各种校验

2.事项列表,包括编辑事项和新增的任务的操作项,(不要问我为什么没有删除项,这里的设计是在我们点击编辑时。有一列“事项状态”,可以更改里面的事项状态来达到删除的作用)

其中还,每个展开行中都会有一个表格,通过点击事项名称或者 “新增任务”按钮 可展开行

3.新增任务:这里给出的需求是在原来有的事项中去新增子事项,我们这里称新任务,那么就是需要新增一行表格,并且表格内要有对应的填写项,而且是可以指定是在任务的前面还是末尾添加一行表格;

4.编辑事项/任务:这两个项时比较相似的,也就是点击编辑可改当前事项的内容

分析: 用到vxe-table,里面比较相像的是tree结构和展开行,但是对于这两种,我们还是选择展开行内嵌入表格。找个主要是考虑展开行的数据是一个有自己表头的单独表格。然后后端返回的数据中也不好定义parentId和自己的id。同时我们这边来看一下后端的数据输出格式:

那就是集展开行、编辑、树形表格于一体,下面我们来直接上代码

结构这块我们可以这样实现: `

            <vxe-table ref="xTable" border show-overflow show-header-overflow :column-config="{resizable: true}"

                <!-- @edit-closed="cancelRowEvent" -->

                <vxe-column field="qe_event_name" title="事项" type="expand">
                    <!-- 展开行 -->
                    <template #content="{row:eventRow,rowIndex:eventRowIndex}">

初始化定义:

const editData = reactive({
    loading: false,
    tableData: [

    ],
    taskOption: ["未开始", "进行中", "已完成", "暂停"],
    eventOption: ["未开始", "进行中", "已完成", "暂停", "归档"],
    tableTooltipConfig: {
        howAll: true,
        enterable: true,
        theme: 'light',
        // contentMethod: ({ type, column, row, items, _columnIndex }) => {
        //     const { field } = column
        //     if (!field) {
        //         return
        //     }
        //     if (field == 'qe_event_link') {
        //         let arrLink = row[field].split(';')
        //         return arrLink.join('\n')
        //     }

        //     //return row[field]
        // }
    },
    taskTooltipConfig: {
        howAll: true,
        enterable: true,
        theme: 'light',
    }
})
    const xTable = ref()

在结构中我们可以观察到有动态树的存在,我们是这么解决的:

        if (el) {
            iframeRefs[key] = el
        }
    };
     const iframeRefs = {}`

对于事件的操作:

//编辑事项
const editRowEvent = (row) => {
        const $table = xTable.value
        $table.setEditRow(row)

    }
//保存事项
const saveRowEvent = (row) => {
        const $table = xTable.value
        $table.clearEdit().then(() => {
            editData.loading = true
            setTimeout(() => {
                editData.loading = false
                let obj = {
                    qe_event_index: row.qe_event_index,
                    qe_event_name: row.qe_event_name,
                    qe_event_creator: row.qe_event_creator,
                    qe_event_detail: row.qe_event_detail,
                    qe_event_estimate: row.qe_event_estimate,
                    qe_event_link: row.qe_event_link,
                    qe_event_status: row.qe_event_status,
                    qe_event_progress: row.qe_event_progress
                    //task_list: row.task_list

                }

                create_event(obj).then(res => {
                    if (res.code == 200) {
                        ElMessage.success(res.message)
                        getTable();

                    } else {
                        ElMessage.error(res.message)
                    }

                })

            }, 300)
        })
    }
//取消保存事项
const cancelRowEvent = () => {
        const $table = xTable.value
        $table.clearEdit().then(() => {
            // 还原行数据
            $table.revertData()
        })
    }



//新增任务
    const addTaskEvent = async (row) => {
        const $fatable = xTable.value
        if (!$fatable.isExpandByRow(row)) {
            await $fatable.toggleRowExpand(row)
        }

        const $table = iframeRefs['tree' + row.qe_event_index]
        const record = {
            qt_task_name: '',
            qt_task_oper: '',
            qt_task_progress: '',
            qt_task_status: '',
            qt_task_create: '',
            qt_task_estimate: '',
            qt_task_link: ''
        }

        const { row: newRow } = await $table.insertAt(record, row.qe_task_list[0])
        await $table.setEditCell(newRow,)
        await $table.setEditRow(newRow);
    }

//编辑任务
const editRowTask = (frow, row) => {
        const $table = iframeRefs['tree' + frow.qe_event_index]
        currentTaskRowKey.value = row.qt_task_index;
        $table.setEditRow(row)
    }

//保存任务
    const saveRowTask = (frow, row, eventRowIndex) => {

        fatherRow.value = frow;
        let task_list_name = frow.qe_task_list.map(item => {
            return item.qt_task_name
        })

        if (row.qt_task_name == '') {
            ElMessage.error('任务名称不能为空')
            return;
        }
        //新增下的任务
        if (!row.qt_task_index) {
            if (task_list_name.indexOf(row.qt_task_name) != -1) {
                ElMessage.warning('新增的任务有重新啦!')
                return;
            }
        }
        //编辑任务
        // if (row.qt_task_index == currentTaskRowKey.value) {
        //     let flagFtype = task_list_others.value.every((item) => !!item.qt_task_name);
        //     if (flagFtype) {
        //         ElMessage.warning('修改后的任务名已经存在啦!')
        //         return;
        //     }
        // }
