json 的操作

json

let data = [  
  {"Networking": "apple", "count_value": "10"},  
	{"Networking": "orange", "count_value": "20"},  
	{"Networking": "banner", "count_value": "30"},

	{"Networking": "banner", "count_value": "90"},  
	{"Networking": "watermelon", "count_value": "40"}  
];
// 合并json中同名key值
	let obj = {};
	for(let i in data){
		if(obj[data[i].Networking]){
			obj[data[i].Networking].value = Number(obj[data[i].Networking].value) + Number(data[i].count_value);
		}else{
			obj[data[i].Networking] = {
				value: Number(data[i].count_value)
			}
		}
	}

//合并两个数组

	let str1=[{name:"11",age:11}];
	let str2=[{name:"22",age:22}];
	
	//1.方法一
	//let str3 = [];
	//for (let i = 0; i < str1.length; i++) {
	//  str3.push(str1[i]);
	//}
	// 
	//for (let i = 0; i < str2.length; i++) {
	//  str3.push(str2[i]);
	//}
	
	//2.方法二
	let str3 = str1.concat(str2);

//获取地址参数
	
	let searchUrl = 'http://10.10.0.200:8081/list?search=%E4%BD%A0%E5%A5%BD'; //window.location.href;
	let searchData = searchUrl.split("=");        //截取 url中的“=”,获得“=”后面的参数
	
	let  searchText = decodeURI(searchData[1]);   //decodeURI解码
