var Arrlist = [
{name:"张三",age:25,time:"2018-07-30 17:45:13"},
{name:"赵六",age:18,time:"2018-07-26 11:10:30"},
{name:"李四",age:28,time:"2018-07-30 16:53:27"},

{name:"王五",age:999,time:"2018-07-28 11:10:30"},
];

var list = [];
var lsitobj = {};
for(var i=0;i<Arrlist.length;i++){
if(!lsitobj[Arrlist[i].name]){
list.push(Arrlist[i])
lsitobj[Arrlist[i].name] = true
}
}
console.log(list)
