我如何获得尺寸为＆＃34; XS＆＃34;的产品？和＆＃34; S＆＃34;和颜色＆＃34;怀特＆＃34; ？

基本上，你可以使用一个回调来测试对象的所需值，如果匹配则返回true。

function (p) {
    return (p.size === 'XS' || p.size === 'S') && p.color === 'White';
}

＆＃13;

var products = [{ "sku": "SKU001", "size": "XS", "color": "Red" }, { "sku": "SKU002", "size": "S", "color": "Blue" }, { "sku": "SKU003", "size": "XS", "color": "Black" }, { "sku": "SKU004", "size": "M", "color": "Red" }, { "sku": "SKU005", "size": "M", "color": "White" }, { "sku": "test1", "size": "S", "color": "White" }, { "sku": "test2", "size": "XS", "color": "White" }],
    result = _.filter(products, function (p) {
        return (p.size === 'XS' || p.size === 'S') && p.color === 'White';
    });

console.log(result);
