How to block click events in uniapp

For developing mobile applications, user interaction experience is crucial. In some cases, we may need to block click events for certain views to avoid user misoperation or negative impact on the application. In Uniapp development, blocking click events is also very easy to implement.

1. Use the Vue command v-on

In Vue, we can use the v-on command to listen to various events, such as clicks, mouse movements, etc., but if we want to block For a click event of a view, you can use the Event.preventDefault() method to prevent the default behavior of the event.

In the code, we can achieve it in the following way:

<template>
  <view v-on:click.stop.prevent="{Handler}"></view>
</template>
<script>
export default {
  methods: {
    Handler() {
      //TODO: 处理点击事件
    }
  }
}
</script>

In this code, the v-on:click.stop.prevent directive prevents the default behavior of the click event, and by calling Handler method to handle click events. If we do not call the preventDefault() method, the click event will be triggered by default when the view is clicked.

2. Use the CSS attribute pointer-events

In addition to the above methods, we can also use the CSS attribute pointer-events to block the click event of the view.

In CSS, the pointer-events attribute defines how mouse events of an element are handled. By setting the pointer-events property to none, you can mask all mouse events on this element and its children.

In Uniapp development, we can achieve it in the following way:

<template>
  <view style="pointer-events:none"></view>
</template>

In this code, we add the pointer-events:none style to the view so that it cannot receive mouse events .

3. Use Touchstart and Touchend events

In Uniapp development, we can also use touchstart and touchend events to prevent the bubbling of touchend events in the touchstart event to achieve shielding click events.

In the code, we can achieve it in the following ways:

<template>
  <view @touchstart.prevent="onTouchStart" @touchend.prevent></view>
</template>
<script>
export default {
  methods: {
    onTouchStart() {
      //TODO: 处理touchstart事件
      event.stopPropagation(); //停止向上冒泡
    }
  }
}
</script>

In this code, we call the stopPropagation() method in the touchstart event to prevent the touchend event from bubbling to achieve shielding Click event effect.

Summary:

The above are three methods to implement shielding click events. In Uniapp development, we can choose different ways to implement it according to our needs. In actual development, we should choose the most appropriate implementation method based on specific scenarios and needs to improve the user experience of mobile applications.
