Current behavior

Pagination 组件中，点选切换pageSize的时候会在发出nzPageSizeChange事件之间先发出一个nzPageIndexClickChange事件。

Expected behavior

点选切换pageSize的时候不再发出nzPageIndexClickChange事件

What is the motivation / use case for changing the behavior?

该bug导致导致在asyncTable中点选每页条目时行为异常；这是由于_buildIndexes方法中调用了_jumpPage方法造成的，而_jumpPage应该只由用户点击操作来调用

Angular version: ^4.0

will be fixed in next version, thanks for your feedback.

@vthinkxie Can add a boolean parameter in the _jumpPage function?

_jumpPage(index, isClick = true) {
    ...
    if (isClick) {
         this.nzPageIndexClickChange.emit(this.nzPageIndex);
    }
  }

correct:

_buildIndexes() {
    this._lastIndex = Math.ceil(this._total / this._pageSize);
    if (this._current > this._lastIndex) {
      // - this._jumpPage(this._lastIndex);
      this.nzPageIndex = this._lastIndex;
      this.nzPageIndexChange.emit(this.nzPageIndex);
    }
   ...
  }
