例如在列表里面筛选出指定用户的数据信息

let obj = {};
let list=[{id:"061gse49",state:1,name:'cc'},{"285jds2",state:0,name:"ruby"},{id:"243kii5",state:0,name:"kk"},{id:"965sfe2",state:1,"yaya"}];

let userId ="965sfe2"
obj = list.find((item) =>{
  return item.id === userId;
})
console.log("obj===",obj);//{id:"965sfe2",state:1,"yaya"}
let curUserId = obj.id;
