uniapp实现图片（单张/多张）预览

一、单张预览

			getImgIndex(index) {
				let imgs = this.temperatureData.map(item => {
					return item.img
				})
				uni.previewImage({
					urls: imgs,
					current: index
				})
			},

二、多张预览

			getImgIndex(index) {
				this.imgArray = [];
				this.imgArray = this.temperatureData[index].img
				uni.previewImage({
					current: 0, //当前为第几张
					urls: this.imgArray,
					indicator: 'number',
					loop: true
				});
			},

效果图：

We’re not put on this Earth to think of only ourselves
