ColorPicker 颜色选择器
用于颜色选择,支持多种格式。
基础用法
:::demo 使用 v-model 与 Vue 实例中的一个变量进行双向绑定,绑定的变量需要是字符串类型。
<div class="block">
<span class="demonstration">有默认值</span>
<el-color-picker v-model="color1"></el-color-picker>
</div>
<div class="block">
<span class="demonstration">无默认值</span>
<el-color-picker v-model="color2"></el-color-picker>
</div>
<script>
export default {
data() {
return {
color1: '#409EFF',
color2: null
}
}
};
</script>
<!--
<setup>
import { defineComponent, ref } from 'vue';
export default defineComponent({
setup() {
const color1 = ref('#409EFF');
const color2 = ref(null);
return {
color1,
color2,
};
},
});
</setup>
-->
:::
选择透明度
:::demo ColorPicker 支持普通颜色,也支持带 Alpha 通道的颜色,通过show-alpha
属性即可控制是否支持透明度的选择。
<el-color-picker v-model="color" show-alpha></el-color-picker>
<script>
export default {
data() {
return {
color: 'rgba(19, 206, 102, 0.8)'
}
}
};
</script>
<!--
<setup>
import { defineComponent, ref } from 'vue';
export default defineComponent({
setup() {
const color = ref('rgba(19, 206, 102, 0.8)');
return {
color,
};
},
});
</setup>
-->
:::
预定义颜色
:::demo ColorPicker 支持预定义颜色
<el-color-picker
v-model="color"
show-alpha
:predefine="predefineColors">
</el-color-picker>
<script>
export default {
data() {
return {
color: 'rgba(255, 69, 0, 0.68)',
predefineColors: [
'#ff4500',
'#ff8c00',
'#ffd700',
'#90ee90',
'#00ced1',
'#1e90ff',
'#c71585',
'rgba(255, 69, 0, 0.68)',
'rgb(255, 120, 0)',
'hsv(51, 100, 98)',
'hsva(120, 40, 94, 0.5)',
'hsl(181, 100%, 37%)',
'hsla(209, 100%, 56%, 0.73)',
'#c7158577'
]
}
}
};
</script>
<!--
<setup>
import { defineComponent, ref } from 'vue';
export default defineComponent({
setup() {
const color = ref('rgba(255, 69, 0, 0.68)');
const predefineColors = ref([
'#ff4500',
'#ff8c00',
'#ffd700',
'#90ee90',
'#00ced1',
'#1e90ff',
'#c71585',
'rgba(255, 69, 0, 0.68)',
'rgb(255, 120, 0)',
'hsv(51, 100, 98)',
'hsva(120, 40, 94, 0.5)',
'hsl(181, 100%, 37%)',
'hsla(209, 100%, 56%, 0.73)',
'#c7158577',
]);
return {
color,
predefineColors,
};
},
});
</setup>

:::
不同尺寸
:::demo
<el-color-picker v-model="color"></el-color-picker>
<el-color-picker v-model="color" size="medium"></el-color-picker>
<el-color-picker v-model="color" size="small"></el-color-picker>
<el-color-picker v-model="color" size="mini"></el-color-picker>
<script>
export default {
data() {
return {
color: '#409EFF'
}
}
};
</script>
<!--
<setup>
import { defineComponent, ref } from 'vue';
export default defineComponent({
setup() {
const color = ref('409EFF');
return {
color,
};
},
});
</setup>
