使用javascript根据对象的属性从数组中删除对象

给定对象数组：

var items = [
{"rank":"3","color":"red"},
{"rank":"4","color":"blue"},
{"rank":"0","color":"green"},
{"rank":"6","color":"blue"},
{"rank":"0","color":"yellow"}
];

我想删除所有排名为0的条目，因此结果将是：

项目：

[{"rank":"3","color":"red"},
{"rank":"4","color":"blue"},
{"rank":"6","color":"blue"}];

    Try to filter by trusy value and apply + sign to convert from string to number:

    var items = [
   {"rank":"3","color":"red"},
   {"rank":"4","color":"blue"},
   {"rank":"0","color":"green"},
   {"rank":"6","color":"blue"},
   {"rank":"0","color":"yellow"}
];

result = items.filter(({rank})=> +rank);
console.log(result);

    应用过滤器：

    var items = [{"rank":"3","color":"red"},{"rank":"4","color":"blue"},{"rank":"0","color":"green"},{"rank":"6","color":"blue"},{"rank":"0","color":"yellow"}];

result = items.filter(({rank})=>rank>0);
console.log(result);

{"rank":"6","color":"blue"},

];

let filteredArray = items.filter(el => el.rank > 0);

console.log(filteredArray);

    您可以使用Array.filter方法执行此操作。

    items = items.filter(i=> {
   return i.rank !== '0';
});

    您可以像这样应用过滤器：

    items = items.filter(el => el.rank != "0")

    您可以将过滤器添加到Items数组：

    items.filter(item => item.rank > 0)
