uview image 的高宽百分比可以通过设置 CSS 样式来实现。你可以在 HTML 中为该元素添加样式,如下所示:
```html
<div style="width: 100%; height: 100%;">
<img src="your_image.jpg" style="width: 100%; height: 100%;" />
</div>
```
这样,uview image 元素的宽度和高度都会占据其父元素的百分之百。同时,内部的 img 元素也会根据父元素的大小进行自适应。

uview2.x中轮播图怎么控制image大小
在uview2.x中轮播图控制image大小,可以通过设置`width`和`height`属性来实现。如下所示:
```html
<swiper :autoplay="true" :interval="3000" :duration="500" :circular="true" :indicator-style="indicatorStyle" :indicator-active-style="indicatorActiveStyle">
<swiper-item v-for="(item, index) in bannerList" :key="index">
<img :src="item.image" mode="aspectFit" style="width: 100%; height: 150rpx;">
</swiper-item>
</swiper>
```
在以上的代码中,通过给`img`标签设置`style`属性来控制图片的大小。其中,`width`设置为100%表示宽度铺满整个轮播图容器,`height`设置为150rpx表示高度为150像素。你可以根据实际需求进行调整。
uView querySelector
`uView` is a UI framework for building cross-platform mobile applications using Vue.js. If you want to use `querySelector` in `uView`, you can do so by following these steps:
1. Import and install `uView` in your project.
2. Create a reference to your component using a ref attribute. For example, `<view ref="myComponent"></view>`.
3. Use the `this.$refs` object to access the component in your Vue methods or lifecycle hooks.
4. Utilize the `querySelector` method on the component reference to select elements within that component's template.
Here's an example of how you can use `querySelector` in a `uView` component:
```vue
<template>
<view ref="myComponent">
<text>Example Text</text>
</view>
</template>
<script>
export default {
mounted() {
const exampleText = this.$refs.myComponent.querySelector('text');
console.log(exampleText); // Print the selected element
},
};
</script>
```
Remember to replace "text" with the appropriate selector for your specific use case.
