## Scrollbar
|
|
|
|
Used to replace the browser's native scrollbar.
|
|
|
|
### Basic usage
|
|
|
|
:::demo Use `height` property to set the height of the scrollbar, or if not set, it adapts according to the parent container height.
|
|
|
|
```html
|
|
<template>
|
|
<el-scrollbar height="400px">
|
|
<p class="item" v-for="item in 20">{{ item }}</p>
|
|
</el-scrollbar>
|
|
</template>
|
|
```
|
|
|
|
:::
|
|
|
|
### Horizontal scroll
|
|
|
|
:::demo When the element width is greater than the scrollbar width, the horizontal scrollbar is displayed.
|
|
|
|
```html
|
|
<template>
|
|
<el-scrollbar>
|
|
<div class="flex-content">
|
|
<p class="item" v-for="item in 50">{{ item }}</p>
|
|
</div>
|
|
</el-scrollbar>
|
|
</template>
|
|
```
|
|
|
|
:::
|
|
|
|
### Max height
|
|
|
|
:::demo The scrollbar is displayed only when the element height exceeds the max height.
|
|
|
|
```html
|
|
<template>
|
|
<el-button @click="add">Add Item</el-button>
|
|
<el-button @click="delete">Delete Item</el-button>
|
|
<el-scrollbar max-height="400px">
|
|
<p class="item" v-for="item in count">{{ item }}</p>
|
|
</el-scrollbar>
|
|
</template>
|
|
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
count: 3,
|
|
}
|
|
},
|
|
methods: {
|
|
add() {
|
|
this.count++
|
|
},
|
|
delete() {
|
|
if (this.count > 0) {
|
|
this.count--
|
|
}
|
|
},
|
|
},
|
|
}
|
|
</script>
|
|
```
|
|
|

### Manual scroll
|
|
|
|
:::demo Use `setScrollTop` and `setScrollLeft` methods can control scrollbar manually.
|
|
|
|
```html
|
|
<template>
|
|
<el-scrollbar ref="scrollbar" height="400px" always @scroll="scroll">
|
|
<div ref="inner">
|
|
<p class="item" v-for="item in 20">{{ item }}</p>
|
|
</div>
|
|
</el-scrollbar>
|
|
|
|
<el-slider
|
|
v-model="value"
|
|
@input="inputSlider"
|
|
:max="max"
|
|
:format-tooltip="formatTooltip"
|
|
></el-slider>
|
|
</template>
|
|
|
|
<script>

|
export default {
|
|
data() {
|
|
return {
|
|
max: 0,
|
|
value: 0,
|
|
}
|
|
},
|
|
mounted() {
|
|
this.max = this.$refs.inner.clientHeight - 380
|
|
},
|
|
methods: {
|
|
inputSlider(value) {
|
|
this.$refs.scrollbar.setScrollTop(value)
|
|
},
|
|
scroll({ scrollTop }) {
|
|
this.value = scrollTop
|
|
},
|
|
formatTooltip(value) {
|
|
return `${value} px`
|
|
},
|
|
