项目中常见的分页显示，第二页从1开始编号，然后在切换分页的过程中，偶现不对，都是小问题，整理记录一下，供参考。
template：
... <el-table-column type="index" label="编号" :index="getIndex" width="80px"> </el-table-column> ... <Pagination :total="total" :pageSize="pageSize" :currentPage="currentPage" @sizeChange="sizeChange" @currentChange="currentChange"> </Pagination>
script：
getIndex (index) {
if (this.currentPage==0){
return (this.currentPage) * this.pageSize + index + 1
} else{
return (this.currentPage-1) * this.pageSize + index + 1
}
},
由于后端第一页是从0开始的，而前端是从第一页开始，所以需要在当前页减1。关于分页，本页条数
sizeChange(val){
let that = this;
that.currentPage = 1;
that.pageSize = val;
that.getPageInfo(that.currentPage, val);
},
跳转页面
currentChange(val){
let that = this;
that.currentPage = val;
that.getPageInfo(val, that.pageSize);
},
页面加载数据
getUserList(currentPage, pageSize){
let that = this;
that.$axios({
method: 'get',
url: '***',
params: {
currentPage: (currentPage || that.currentPage || 1)-1,
pageSize: pageSize || that.pageSize || 10
},
needInterceptors: true,
showError: true,
loader: true
}).then(function(result){
let data = result && result.data || [];
let page = result && result.pageCont || {};
that.total = page.totalItems || 0;
that.tableData = data;
})
},
试了几次，这样写应该是没有问题的，也解决了后端传0开始的问题。
