HarmonyOS Next开发学习手册——基础组件(rating开发）

rating为评分条组件，表示用户使用感受的衡量标准条。

创建rating组件

在pages/index目录下的hml文件中创建一个rating组件。

<!-- xxx.hml -->
<div class="container">
  <rating></rating>
</div>

---

.container {
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
  background-color: #F1F3F5;
}
rating {
  width: 80%;
  height: 150px;
}

设置评分星级

rating组件通过设置numstars和rating属性设置评分条的星级总数和当前评星数。

<!-- xxx.hml -->
<div class="container">
  <rating numstars="6" rating="5">
  </rating>
</div>

---

/* xxx.css */
.container {
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
  background-color: #F1F3F5;
}
rating {
  width: 80%;
  height: 150px;
}

设置评分样式

rating组件通过star-background、star-foreground和star-secondary属性设置单个星级未选择、选中和选中的次级背景图片。

<!-- xxx.hml -->
<div class="container">
  <div style="width: 500px;height: 500px;align-items: center;justify-content: center;flex-direction: column;;">
    <rating numstars="5" rating="1" class="myrating" style="width: {
  
  {ratewidth}}; height:{
  
  {rateheight}};
    star-background: {
  
  {backstar}}; star-secondary: {
  
  {secstar}};star-foreground: {
  
  {forestar}};rtl-flip: true;">
    </rating>
  </div>
</div>

---

/* xxx.css */
.container {
  width: 100%;
  height: 100%;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  background-color: #F1F3F5;
}

// index.js
export default {
  data: {
    backstar: 'common/love.png',
    secstar: 'common/love.png',
    forestar:
