vue- elementUi 分页偶数

在element分页中使用pager-count报错:

Invalid prop: custom validator check Failed for prop "pagerCount"

官网文档

解决

1. 修改源码验证部分

pagerCount: {
  type: Number,
  validator(value) {
    return (value | 0) === value && value > 4 && value < 22 && (value % 2) === 1;
  },
  default: 7
},

2. 数据处理

<el-pagination :pager-count="data.pagerCount"></el-pagination>

this.isEven = data.pagerCount % 2 === 0;
if (this.isEven) {
  data.pagerCount += 1;
  this.$nextTick(() => {
    let quicknextDom =
      this.$el.getElementsByClassName('btn-quicknext')[0];
    quicknextDom.prevIoUsSibling.style.display = 'none';
  });
}
