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:

<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.
