elementui 分页page-size current-page 不随着组件改变问题

问题出在未使用  .sync 上!

    :current-page.sync="pageData.PageIndex"

   :page-size.sync='pageData.PageSize'

  //

PageSize 还有参数大小写的问题 检查是否一致

<el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page.sync="pageData.PageIndex"
      :page-sizes ="pageData.PageSizes"
      :page-size.sync='pageData.PageSize'
      layout="total, sizes, prev, pager, next, jumper"
      :total="pageData.total"
    >
    </el-pagination>

 

 

//分页条件
      pageData: {
        PageIndex: 1,
        PageSize: 10,
        PageSizes: [5, 10, 20, 30, 40],
        Order: "",
        total: 0,
      },
