### Element UI Image Component Documentation and Examples
Element UI provides a versatile `el-image` component designed specifically for handling images within applications efficiently. The following details cover its usage, properties, events, slots, and methods.
#### Basic Usage Example
To integrate the `el-image` into your project, ensure that Element UI is installed and imported correctly. Below demonstrates how to use this component:
```html
<template>
<div class="demo-image">
<div class="block" v-for="fit in fits" :key="fit">
<span>{{ fit }}</span>
<el-image style="width: 100px; height: 100px" :src="url" :fit="fit"></el-image>
</div>
</div>
</template>
<script>
export default {
data() {
return {
url: 'https://fuss10.elemecdn.com/e/5d/4a731a90594a4af544c0c25941171jpeg.jpeg',
fits: ['fill', 'contain', 'cover', 'none', 'scale-down']
};
}
};
</script>
```
The above code snippet showcases different fitting options available when displaying an image through the `el-image` tag[^1].
#### Properties Explained
Several attributes can customize the behavior of the displayed image:
- **alt**: Alternative text description.
- **src**: Source URL string pointing towards the desired image file location.
- **lazy**: Boolean flag enabling lazy loading functionality which loads only visible elements initially improving performance especially on pages containing many images.
- **scroll-container**: Selector identifying container element responsible for triggering scroll event used alongside lazy load feature.
- **preview-src-list**: Array holding URLs intended for preview mode allowing users to view larger versions upon clicking smaller thumbnails.
- **z-index**: Controls stacking order during previews ensuring proper layering among multiple overlapping components.
- **referrerpolicy**: Specifies referrer information included while fetching resources adheres W3C specification guidelines enhancing security measures against potential leaks.
These configurable parameters provide flexibility catering various requirements ranging simple static displays up till complex interactive galleries.
#### Events Supported
Event listeners attached directly onto `<el-image>` tags allow developers to react accordingly based on user interactions or internal state changes like successful fetch completion (`load`) or failure (`error`). Handling these scenarios gracefully ensures robustness under unpredictable network conditions maintaining good UX standards expected today's web apps.
#### Slots Available
Customization extends beyond mere attribute settings thanks to named slot support offering greater control over layout design aspects including but not limited to placeholder visuals shown before actual media becomes ready after being fetched remotely from servers across internet connections varying speeds reliability levels etcetera:
- **default**: Content rendered inside custom placeholders until main object fully loaded replacing temporary markers seamlessly once completed without disrupting overall flow experience negatively impacting end-users perception quality service provided online platforms striving excellence every aspect interaction possible.
In summary, mastering utilization possibilities offered via comprehensive set features embedded within `el-image` empowers creators build visually appealing interfaces capable delivering rich multimedia experiences effortlessly meeting modern expectations effectively addressing diverse needs audiences worldwide seeking engaging digital spaces fostering communication collaboration innovation alike.
