假如数组为

				swiperList: [{
					img: "../../../static/logo.png",
					name: "THIS IS a"
					img: "../../../static/logo.png",
					name: "THIS IS b"
					img: "../../../static/logo.png",
					name: "THIS IS c"
					img: "../../../static/logo.png",
					name: "THIS IS d"
				}]

如果变成[[],[]]，里面的数组里面有2个元素

				[
						"img": "../../../static/logo.png",
						"name": "THIS IS a"
						"img": "../../../static/logo.png",
						"name": "THIS IS b"
						"img": "../../../static/logo.png",
						"name": "THIS IS c"
						"img": "../../../static/logo.png",
						"name": "THIS IS d"
				]

		computed: {
			resultSwiperList() {
				let pages = []
				this.swiperList.forEach((item, index) => {
					let page = Math.floor(index / 2)
					if (!pages[page]) {
						pages[page] = []
