我想在js中实现这样的功能
function(arrayOfObjects, arrayOfValues, property) {
/*here i want to return all the objects of 'arrayOfObjects'
which satisfies the following condition
(index is the iterative index of array 'arrayOfObjects')
arrayOfObjects[index][property] is equivalent to any of
the values that lies in arrayOfValues */
};
例如：
arrayOfObjects = [{ a: 1, b: 2 }, { a: 3, b:4 }, { a: 1, b :3 }];
arrayOfValues = [ 2, 3 ];
function(arrayOfObjects, arrayOfValues, 'b')
应该
return [{ a: 1, b: 2 }, { a: 1, b :3 }] 最佳答案
arrayOfObjects.filter(function (elem) {
return elem.hasOwnProperty(property)
&& -1 !== arrayOfValues.indexOf(elem[property]);
});
如果需要IE8支持：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter#Compatibility
关于javascript - js中是否有类似``谎言''运算符的东西，因为我们的 Mongoose /mongo中有``$ in''，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/20474243/
