[MuyePeikon]

Element UI version

2.2.1

OS/Browsers version

Chrome

Vue version

2.5.16

Reproduction Link

https://jsfiddle.net/e8v5za0f/

Steps to reproduce

1. change the page-size to 400;
2. change jumper to a big number (keep on focus status && without press enter key);
3. change the page-size to 100/200/300;

What is Expected?

After step 3, jumper can stay with number 1.

What is actually happening?

At the start of step 3, jumper will change to 1. But after step 3, jumper will change to the big number you enter in step 2.
Besides, if u clear the number in step 2, then after step 3, the number in jumper will be cleared too.
