|
|
The last few challenges showed that each object in the JSON array contains an `imageLink` key with a value that is the URL of a cat's image.
|
|
|
|
|
|
|
|
When you're looping through these objects, you can use this `imageLink` property to display this image in an `img` element.
|
|
|
|
|

|
|
|
Here's the code that does this:
|
|
|
|
|
2020-11-27 19:02:05 +01:00
|
|
|
`html += "<img src = '" + val.imageLink + "' " + "alt='" + val.altText + "'>";`
|
|
|
|
|
|
|
|

2020-11-27 19:02:05 +01:00
|
|
|
Add code to use the `imageLink` and `altText` properties in an `img` tag.

|
|
You should use the `imageLink` property to display the images.
|
|
|
|
|
|
|
|
```js
|
|
|
|
assert(code.match(/val\.imageLink/g));
|
2018-09-30 23:01:58 +01:00
|
|
|
```
|
|
|
|
|
2020-11-27 19:02:05 +01:00
|
|
|
You should use the `altText` for the alt attribute values of the images.
|
|
|
|
|
|
|
|
```js
|
|
|
|
assert(code.match(/val\.altText/g));
|
|
|
|
```
