javascript - 给定一个 JSON 对象，如何根据键查找项目？

Question

给定一个 JSON 对象，例如:

var data = {items: [
{value: "21", name: "Mick Jagger"},
{value: "43", name: "Johnny Storm"},
{value: "46", name: "Richard Hatch"},
{value: "54", name: "Kelly Slater"},
{value: "55", name: "Rudy Hamilton"},
{value: "79", name: "Michael Jordan"}
]};

我怎样才能做这样的事情:

datagood = data.where(value == 55)

JS/jQuery 可以实现类似的功能吗？谢谢

Answer 1

jQuery's grep function允许您过滤数组:

var datagood = $.grep(data.items, function (item) {
    return item.value == 55;
});

如果您想要更强大的实用程序，请查看 this SO question on JS LINQ libraries .

或者，underscore.js对于数组/对象操作也很有用。
