# Layout 布局

通过基础的 12 分栏,迅速简便地创建布局

注意

如需实现类似宫格的布局,请使用uView的Grid宫格组件,可以设置角标,功能更完善和灵活

# 平台差异说明

# 基本使用

通过col组件的span设置需要分栏的比例

<template>
    <view class="u-page">
        <view class="u-demo-block">
            <text class="u-demo-block__title">基础使用</text>
            <view class="u-demo-block__content">
                <u-row customStyle="margin-bottom: 10px">
                    <u-col span="6">
                        <view class="demo-layout bg-purple-light"></view>
                    </u-col>

                </u-row>
                <u-row customStyle="margin-bottom: 10px">
                    <u-col span="4">
                        <view class="demo-layout bg-purple"></view>
                    </u-col>
                    <u-col span="4">
                        <view class="demo-layout bg-purple-light"></view>
                    </u-col>
                    <u-col span="4">
                        <view class="demo-layout bg-purple-dark"></view>
                    </u-col>
                </u-row>
                <u-row justify="space-between">
                    <u-col span="3">
                        <view class="demo-layout bg-purple"></view>
                    </u-col>
                    <u-col span="3">
                        <view class="demo-layout bg-purple-light"></view>
                    </u-col>
                    <u-col span="3">
                        <view class="demo-layout bg-purple"></view>
                    </u-col>
                    <u-col span="3">
                        <view class="demo-layout bg-purple-light"></view>
                    </u-col>
                </u-row>
            </view>
        </view>
    </view>
</template>

<style lang="scss">
    .wrap {
        padding: 12px;
    }

    .demo-layout {
        height: 25px;
        border-radius: 4px;
    }

    .bg-purple {
        background: #CED7E1;
    }

    .bg-purple-light {
        background: #e5e9f2;
    }

    .bg-purple-dark {
        background: #99a9bf;
    }
</style>

# 分栏间隔

通过设置row组件的gutter参数,来指定每一栏之间的间隔(最终表现为左边内边距各为gutter/2),默认间隔为0

<view class="u-demo-block__content">
    <u-row
            justify="space-between"
            gutter="10"
    >
        <u-col span="3">
            <view class="demo-layout bg-purple"></view>
        </u-col>
        <u-col span="3">
            <view class="demo-layout bg-purple-light"></view>
        </u-col>
        <u-col span="3">
            <view class="demo-layout bg-purple"></view>
        </u-col>
        <u-col span="3">
            <view class="demo-layout bg-purple-light"></view>
        </u-col>
    </u-row>
</view>

<style lang="scss">
    .wrap {
        padding: 12px;
    }

    .demo-layout {
        height: 25px;
        border-radius: 4px;
    }

    .bg-purple {
        background: #CED7E1;
    }

    .bg-purple-light {
        background: #e5e9f2;
    }

    .bg-purple-dark {
        background: #99a9bf;
    }
</style>

# 混合布局

通过指定col组件的span属性,指定不同的值,达到不同的比例

<view class="u-demo-block__content">
    <u-row
        justify="space-between"
        gutter="10"
    >
        <u-col span="2">
            <view class="demo-layout bg-purple-light"></view>
        </u-col>
        <u-col span="4">
            <view class="demo-layout bg-purple"></view>
        </u-col>
        <u-col span="6">
            <view class="demo-layout bg-purple-dark"></view>
        </u-col>
    </u-row>
</view>

<style lang="scss">
    .wrap {
        padding: 12px;
    }

    .demo-layout {
        height: 25px;
        border-radius: 4px;
    }

    .bg-purple {
        background: #CED7E1;
    }

    .bg-purple-light {
        background: #e5e9f2;
    }

    .bg-purple-dark {
        background: #99a9bf;
    }
</style>

# 分栏偏移

通过指定col组件的offset属性可以指定分栏偏移的栏数。

<view class="u-demo-block__content">
    <u-row
            justify="space-between"
            customStyle="margin-bottom: 10px"
    >
        <u-col
                span="3"
                offset="3"
        >
            <view class="demo-layout bg-purple-light"></view>
        </u-col>
        <u-col
                span="3"
                offset="3"
        >
            <view class="demo-layout bg-purple"></view>
        </u-col>
    </u-row>
    <u-row>
        <u-col span="3">
            <view class="demo-layout bg-purple-light"></view>
        </u-col>
        <u-col
                span="3"
                offset="3"
        >
            <view class="demo-layout bg-purple"></view>
        </u-col>
    </u-row>
</view>

# 对齐方式

通过row组件的justify来对分栏进行灵活的对齐, 可选值为start(或flex-start)、end(或flex-end)、centeraround(或space-around)、between(或space-between), 其最终的表现类似于css的justify-content属性。

注意:由于持微信小程序编译后的特殊结构,此方式不支持微信小程序。

<view class="u-demo-block__content">
    <u-row
            justify="space-between"
            customStyle="margin-bottom: 10px"
    >
        <u-col
                span="3"
        >
            <view class="demo-layout bg-purple-light"></view>
        </u-col>
        <u-col
                span="3"
        >
            <view class="demo-layout bg-purple"></view>
        </u-col>
    </u-row>
    <u-row>
        <u-col span="3">
            <view class="demo-layout bg-purple-light"></view>
        </u-col>
        <u-col
                span="3"
        >
            <view class="demo-layout bg-purple"></view>
        </u-col>
    </u-row>
</view>
