uniapp 图片长按会之后会出现默认菜单，移动端会出现复制、分享等。我是直接封装成一个图片组件，长按和点击会触发不同的事件类型，图片组件如下：

javascript 复制代码

<template>
	<view>
		<image v-bind="$attrs" @touchstart="imgTouchStart" @touchend="imgTouchEnd"></image>
	</view>
</template>

<script setup>
	const props = defineProps({
		time:{//触发长按逻辑的时常，单位ms
			type:Number,
			default:800
		},
		stop:{//是否需要组织冒泡
			type:Boolean,
			default:true
		}
	})
	const emits = defineEmits(['customerClick'])
	let pressTimer = null;
	let longPressTriggered = false;
	const imgTouchStart = e => {
		e && e.preventDefault()
		if(props.stop){
			e && e.stopPropagation()
		}
		longPressTriggered = false;
		pressTimer = setTimeout(() => {
			longPressTriggered = true;
			emits('customerClick',{type:'longpress'})
		}, props.time);
	}
	
	const imgTouchEnd = (e) => {
		if(props.stop){
			e && e.stopPropagation()
		}
		pressTimer && clearTimeout(pressTimer);
		if (!longPressTriggered) {
			emits('customerClick',{type:'click'})
		}
	}
	
</script>

<style>
</style>

使用如下：

javascript 复制代码

<template>
    //组件名称自定义
    <sbtImage class="image no-select" :src="src" @customerClick="data=>imageClick(data,item)"></sbtImage>
</template>

<script setup>

const imageClick = (e,data) => {
	if(e.type == 'longpress'){
		//长按事件的处理逻辑
	}else if(e.type == 'click'){
		//点击事件的处理逻辑
	}
}
</script>
