栅格布局


栅格布局

栅格布局容器根节点,使用grid-row与grid-col进行栅格布局。具体请参考Grid-container

创建grid-container组件

在pages/index目录下的hml文件中创建一个grid-container组件,并添加Grid-row子组件。

<!-- index.hml -->
<div class="container">
  <grid-container id="mygrid" columns="5" gutter="20px" style="background-color: pink;">
    <grid-row style="height:100px;justify-content:space-around;width: 80%;background-color: #f67002;margin-left: 
      10%;"></grid-row>
    <grid-row style="height:300px;justify-content:space-around;background-color: #ffcf00;width: 100%;"></grid-row>
    <grid-row style="height:150px;justify-content:space-around;background-color: #032cf8;width: 100%;"></grid-row>
  </grid-container>
</div>

调用方法

grid-container点击组件调用getColumns、getColumnWidth、getGutterWidth方法,返回栅格容器列数、column宽度及gutter宽度。长按调用getSizeType方法返回当前容器响应尺寸类型(xs|sm|md|lg)。

<!-- index.hml -->
<div class="container">
  <grid-container id="mygrid" columns="6" gutter="20px" style="background-color: pink;padding-top: 100px;" 
    onclick="getColumns" onlongpress="getSizeType">
    <grid-row style="height:100px;justify-content:space-around;background-color: #4cedf3;width: 20%;margin-left: 
      40%;"></grid-row>
    <grid-row style="height:150px;justify-content:space-around;background-color: #4cbff3;width: 50%;margin-left:
      25%;"></grid-row>
    <grid-row style="height:200px;justify-content:space-around;background-color: #465ff6;width: 80%;margin-left: 
      10%;"></grid-row>
    <grid-row style="height:200px;justify-content:space-around;background-color: #5011ec;width: 100%;"></grid-row>
  </grid-container>

添加grild-col

创建grid-container组件并添加grid-row,在grid-row组件内添加grild-col组件形成布局。

<!-- index.hml -->
<div class="container">
  <grid-container id="mygrid" columns="4" gutter="0" style="background-color: pink;" onclick="getColumns" onlongpress="getSizeType">
    <grid-row style="height: 100px;justify-content: space-around;background-color: #4cbff3;width: 100%;">
      <grid-col span="0">
        <div style="align-items: center;justify-content: center;height: 100%;width: 100%;">
          <text style="color: dodgerblue;" onclick="getCol">top</text>
        </div>
      </grid-col>
    </grid-row>
    <grid-row style="height:500px;justify-content:space-around;background-color: #3b55ef;width: 100%;">
      <grid-col span="0" style="width: 20%;">
        <div style="align-items: center;justify-content: center;height: 100%;width: 100%;">
          <text style="color: dodgerblue;">left</text>
        </div>
      </grid-col>
      <grid-col span="0" style="background-color:orange;width: 80%;">
        <div style="width: 100%;height: 100%;align-items: center;justify-content: center;">
          <text>right</text>
        </div>
      </grid-col>
    </grid-row>
    <grid-row style="height: 100px;justify-content: space-around;background-color: #4cbff3;width: 100%;">
      <grid-col style="background-color:#c075ef;" span="0">
        <div style="width: 100%;height: 100%;padding: 20px;align-items: center;justify-content: center;">
          <text>bottom</text>

icon-note.gif 说明: grid-row仅支持grid-col为子组件,只能在grid-col组件中添加填充的内容。

场景示例

本场景中循环输出list中的内容,创建出网格布局。进行下拉操时触发refresh(刷新页面)方法,这时会向list数组中添加一条数据并设置setTimeout(延迟触发),达到刷新请求数据的效果。

<!-- index.hml -->
<div class="container">
  <refresh refreshing="{{fresh}}" onrefresh="refresh">
    <grid-container id="mygrid" gutter="20" style="margin: 10px;">
      <grid-row style="height:200px;width: 100%;background-color: #e7e7e2;margin-top: 50px; padding: 0px 20px;border-radius: 15px;" for="item in list">
        <grid-col span="0" style="width: 40%;">
          <div style="align-items: center;justify-content: center">
            <image src="{{item.src}}" style="object-fit: contain;border-radius: 30px;"></image>
          </div>
        </grid-col>
        <grid-col span="0" style="width: 60%;">
          <div style="align-items: center;justify-content: center;width: 100%;height: 100%;text-align: center;">
            <text>image{{item.id}}</text>
          </div>
        </grid-col>
      </grid-row>
    </grid-container>
  </refresh>
