uni-app将rpx转px

        sizeDeal(size) {
		    const info = uni.getSystemInfoSync()
		    const scale = 750 / info.windowWidth;
			// 分离字体大小和单位,rpx 转 px
			let s = Number.isNaN(parseFloat(size)) ? 0 : parseFloat(size)
			let u = size.toString().replace(/[0-9]/g, '').replace('-','')
			if (u == 'rpx') {
				s /= scale
				u = 'px'
			} else if (u == '') {
				u = 'px'
			}else if (u == 'vw') {
				u = 'px'
				s = s / 100 * 750 / scale
			}
			return [s, u, s + u]
