字符截取对象

	onLoad() {
				let url = "type=1&page=1&size=20&sort=1&brand=SANY"
				let arr = this.ce(url)
						let str = url.split('&')
						let ob = {}
						str.map((item, index) => {
							let name=  item.substring(0,item.lastIndexOf("="))
							arr.map((i,o)=>{
								if(name==i){
									//ob[`${name}`]=item.slice(item.lastIndexOf('=')+ 1)
ob[name]=item.slice(item.lastIndexOf('=')+ 1)
								}
							})
						})
						console.log(ob)
		},
		// 从前台进入后台
		onHide() {},
		methods: {
			 ce (data,item , index){
				 let ddd = { }
				 let url = data
				 		let str = url.split('&')
				 		return str.map((item, index) => {
				 			let name=  item.substring(0,item.lastIndexOf("="))
							return name
				 		})
			 },
}

第二种

let url = "type=1&page=1&size=20&sort=1&brand=SANY"
			const str = url.split('&')
			const newstr = []
			for (let i = 0; i < str.length; i++) {
				newstr.push(str[i])
			}
			const paramObj = newstr.reduce((prev, current) => {
				current = current.replace(/\"/g, ''); // 去掉双引号
				const [key, value] = current.split("="); // 分离键值对
				prev[key] = value; // 设置为对象属性
				return prev;
			}, {});
			console.log(paramObj)
