vue表格多选切换分页保持勾选状态
LBJsagiri 人气:0第一种情况（配合后端做选中数据处理）
定义三个参数，是否为全选（isSelectAll）、不是全选时选择的数据（selectObject： []）、反选数据（unSelectObject：[]）
HTML

data: [], isSelectAll: false, condition: '', selectObject: [], unSelectObject: [], selectEquipsIds: '0',
JS
// 全选
onSelectAll() {
this.isSelectAll = true
this.getDataList()
},
//取消全选
selectAllcancel() {
this.isSelectAll = false
this.selectEquipsIds = '0'
this.getDataList()
},
//全选当前页
selectAll() {
if (this.isSelectAll) {
for (let i = this.data.length - 1; i >= 0; i--) {
var _index = this.unSelectObject.indexOf(this.data[i].id)
if (_index != -1) {
this.unSelectObject.splice(_index, 1)

console.log(this.unSelectObject)
} else {

console.log(this.selectObject)

console.log(this.unSelectObject)

var _index = this.selectObject.indexOf(this.data[i].id)
if (_index != -1) {
this.selectObject.splice(_index, 1)

console.log(this.selectObject)

},
// 选中一行
TableSelectRow(selection, row) {
if (this.isSelectAll) {
var _index = this.unSelectObject.indexOf(row.id)
if (_index != -1) {
this.unSelectObject.splice(_index, 1)
console.log(this.unSelectObject)
}
} else {
if (!this.selectObject.includes(row.id)) {
this.selectObject.push(row.id)
console.log(this.selectObject)

// 判断是否选中

api().then((res) => {

if (res.success) {

this.sortData() //分页时保留选中状态
if (this.data.length == 0 && this.searchForm.pageIndex > 1) {
this.searchForm.pageIndex -= 1
this.getDataList()
}
}
})
},实现效果
全选效果
单独选择效果
整页全选选择效果
整页全选＋单选
第二种情况（只给后端传需要传的数据）
定义一个参数，已选数据（selectObject：[]）
HTML

// 选择分页数
onPageSizeChange(param) {

this.loading = true
api().then((res) => {

if (this.data.length == 0 && this.searchForm.pageIndex > 1) {

})
},
},以上均已实测可用。
