有没有一种简单的方法来查找基于属性值的列表中的对象，不用循环就行了？

Is there a simple way to find an object in a list based on an attribute value, without looping on the list?

例如给出类似下面的列表：

For example given a list like the following :

var lst = [{name : "foo", value : "fooValue"}, {name: "bar", value: "barValue"}];

是有某种找到的方法，这样， lst.find（名，富）将返回其中有一个名称的对象，其值为foo的属性？

is there some kind of "find" method, such that lst.find("name", "foo") would return the object which has a "name" attribute with the value "foo"?

推荐答案

您可以使用$过滤服务：

You can use the $filter service:

angular.module('app', [])

function ParentCtrl($scope, $filter){
    var lst = [{name : "foo", value : "fooValue"}, {name: "bar", value: "barValue"}, { name: 'foo', value: 'something else'}];
    var newTemp = $filter("filter")(lst, {name:'foo'});
    console.log(newTemp);
}
