Where is the uniapp click event written?

uniapp is a cross-platform framework developed based on Vue.js. It aims to achieve the goal of once development and multi-platform operation. It is compatible with almost all mainstream mobile device operating systems on the market. When developing a uniapp application, click events are an integral part of the development process. This article will discuss where the click events in uniapp should be written.

In uniapp, you can use the v-on directive to add click events. Normally, we will write the click event in the script of the page. For example, when we click a button on the page, the corresponding click event can be triggered in the following way:

<template>
  <button @click="handleClick">点击我</button>
</template>

<script>
  export default {
    methods: {
      handleClick() {
        console.log('点击事件触发')
      }
    }
  }
</script>

In this example, we render the button in the template and define a handleClick method and bind it to the button using the @click directive. When we click the button, the handleClick method will be triggered and output a simple console message.

In addition to writing the click event in the script of the page, another common implementation method is to pass the click event as the props of the component. This method is usually used when the reusability of components is high. By passing the click event to the component as a property in the props object, you can make the component's click event easier to reuse. For example:

<template>
  <myButton :onClick="handleClick" />
</template>

<script>
  import myButton from './myButton.vue'
  
  export default {
    components: {
      myButton
    },
    methods: {
      handleClick() {
        console.log('点击事件触发')
      }
    }
  }
</script>

In this example, we create a component named myButton and pass the handleClick method to the component as onClick props. In the implementation of the myButton component, we can use props to receive the onClick attribute and bind it to the button through the v-on directive to implement the click event.

In short, whether you write the click event in the script of the page or pass it to the component as the props of the component, you can implement the click event in uniapp. Developers can choose the most appropriate implementation method based on the actual needs of the project and combined with the design and development requirements of the components.
