1. 获取 url 的参数
function getParameter(parName){
var str = parName.toLowerCase() + "=";
var gvalue = "";
var HREF = location.href;
var upperHREF = location.href.toLowerCase();
if(upperHREF.indexOf(str)>0){
gvalue = HREF.substring(upperHREF.indexOf(str) + str.length,upperHREF.length);
if(gvalue.indexOf('&')>0) gvalue = gvalue.substring(0,gvalue.indexOf('&'));
if(gvalue.indexOf("#")>0) gvalue = gvalue.split("#")[0];
}
return gvalue;
}
2. 数组对象 根据条件过滤
(1). 获取年龄 18 的数据
let array = [{id:1,name:"靓仔",age:18},{id:2,name:"靓女",age:18},{id:3,name:"瘦子",age:16},{id:4,name:"肥仔",age:28}]
function filterAge (array=[]){
let array = [{id:1,name:"靓仔",age:18},{id:2,name:"靓女",age:18},{id:3,name:"瘦子",age:16},{id:4,name:"肥仔",age:28}]
function filterId (array=[]){
