Can uniapp directly call the click event?

In modern web design, the click event is one of the most important interactive events. The click event is an event triggered when the user clicks or taps an element. Although click events are very common in web design, how to call click events in mobile application design is worth discussing.

In the uniapp framework, we can use @tap to bind the click event of an element. The @tap event is an event triggering method encapsulated by the uniapp framework, which is equivalent to the click event. However, if you really want to use the click event, you can also use native JS to implement the click event in uniapp.

How to use click event directly? First, in uniapp, we can refer to an element by using ref. For example, the code in the template is as follows:

<template>
  <div ref="myDiv">click me</div>
</template>

In the above code, we refer to the element as myDiv through the ref directive.

Next, we need to bind a click event to the element. In the uniapp framework, we can implement this function through the mounted life cycle function. Modify the above code:

<template>
  <div ref="myDiv" @click="handleClick">click me</div>
</template>

<script>
export default {
  methods: {
    handleClick() {
      console.log('Clicked!');
    }
  },
  mounted() {
    const myDiv = this.$refs.myDiv;
    myDiv.addEventListener('click', this.handleClick);
  }
};
</script>

We bind the click event to $refs, and add a click listener to the element in the mounted life cycle function. Finally, we need to call a named function handleClick() To implement the click event function.

It should be noted that before removing the component, we need to use the removeEventListener() method to remove the click listener of the element. This step needs to be kept in mind to avoid problems such as memory leaks.

In general, although the @tap event is provided in the uniapp framework to bind and monitor element click events, the click event in native JS can also be implemented in the uniapp framework. We can achieve this by first referencing the element (using ref) and then binding the click event listener in the mounted lifecycle function.
