javascript - Why does the zoom attribute in the image automatically add the domain name when using js to zoom in and out?

Question

The code I added is this,

<img src="https://img.alicdn.com/bao/uploaded/i1/1435205015500799928/TB2YGP.bncCL1FjSZFPXXXZgpXa_!!0-rate.jpg_40x40.jpg" data-action="zoom" src="https://img.alicdn.com/bao/uploaded/i1/1435205015500799928/TB2YGP.bncCL1FjSZFPXXXZgpXa_!!0-rate.jpg_400x400.jpg" />
            <img src="https://img.alicdn.com/bao/uploaded/i1/1435205015500799928/TB2YGP.bncCL1FjSZFPXXXZgpXa_!!0-rate.jpg_40x40.jpg" data-action="zoom" src="https://img.alicdn.com/bao/uploaded/i1/1435205015500799928/TB2YGP.bncCL1FjSZFPXXXZgpXa_!!0-rate.jpg_400x400.jpg" />

But after execution, it becomes like this

<img src="https://img.alicdn.com/bao/uploaded/i1/1435205015500799928/TB2YGP.bncCL1FjSZFPXXXZgpXa_!!0-rate.jpg_40x40.jpg" **data-action="www.baidu.com/zoom"** src="https://img.alicdn.com/bao/uploaded/i1/1435205015500799928/TB2YGP.bncCL1FjSZFPXXXZgpXa_!!0-rate.jpg_400x400.jpg" />

I don’t know why after execution, the data-action="zoom"
becomes like this data-action="www.baidu.com/zoom"

I use this js

Are there any troubleshooting methods?

Answer 1

Okay, just change the data-action to other characters and it will be done. The reason is unknown

Answer 2

Put a breakpoint on js and take a look
