html
<el-pagination
background
layout="sizes, prev, pager, next, jumper, total"
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:total="1000">
</el-pagination>
<script>
export default {
methods: {
handleSizeChange: function (val) {
alert("每页记录数变化" + val)
},
handleCurrentChange: function (val) {
alert("页码发生变化" + val)
}
}
}
</script>
layout 与下面组件的对应关系
size-change 和 current-change 事件来处理页码大小和当前页变动时候触发的事件。
