next

@StevenYuysy 删除jumper中的数字后，当前页跳到第1页并不是点击next直接导致的，而是jumper失焦后其值此时为空字符串，应用值到internalCurrentPage前会校验设置的页码，部分源码如下，会被设置为1：

getValidCurrentPage(value) {
      value = parseInt(value, 10);
      // ...
      if (resetValue === undefined && isNaN(value)) {
        resetValue = 1; // here
      } else if (resetValue === 0) {
        resetValue = 1;
      }
      return resetValue === undefined ? value : resetValue;
    }
  }

@huguangju
jumper 失焦时 innerCurrentPage 被设置为 0，但是实际上，失焦的时候，页面没有发生跳转， innerCurrentPage 不应该会发生变化。

[huguangju]

@StevenYuysy innerCurrentPage 不会被设置为 0的。不过这里似乎存在问题，正常情况下，在 jumper
中输入页码后，仅应在按下回车键再作跳转比较合理。例如，我想跳到第20页，输完之后改变了主意想先直接点到第二页看看，目前的情况就是：当点击第二页时，会首先跳到第20页（若pageCount小于20则跳到pageCount），然后才会跳到第二页，也就是说 @current-change 会执行两次。
