基于其他数组过滤对象上的数组(Filter an array on objects based on an other array)
我是这样的arry
var data = [{ category: "2014-1-1", subCategory: [{ name: "shoe", val: 70, toolTip: "toolTip-shoe-70", drill: false }, { name: "pant", val: 60, toolTip: "toolTip-pant-60", drill: false }, { name: "shirt", val: 50, toolTip: "toolTip-shirt-50", drill: false }, { name: "Tshirt", val: 40, toolTip: "toolTip-Tshirt-40", drill: true }, { name: "socks", val: 30, toolTip: "toolTip-socks-30", drill: false }, { name: "watchs", val: 20, toolTip: "toolTip-watchs-20", drill: false }, { name: "hats", val: 10, toolTip: "toolTip-hats-10", drill: false }] }, { category: "2014-3-2", subCategory: [{ name: "shoe", val: 16, toolTip: "toolTip-shoe-16", drill: false }, { name: "pant", val: 12, toolTip: "toolTip-pant-12", drill: false }, { name: "shirt", val: 14, toolTip: "toolTip-shirt-14", drill: false }, { name: "Tshirt", val: 13, toolTip: "toolTip-Tshirt-13", drill: false }, { name: "socks", val: 22, toolTip: "toolTip-socks-22", drill: true }, { name: "watchs", val: 31, toolTip: "toolTip-watchs-31", drill: false }, { name: "hats", val: 21, toolTip: "toolTip-hats-21", drill: false }] }, { category: "2014-6-3", subCategory: [{ name: "shoe", val: 22, toolTip: "toolTip-shoe-22", drill: false }, { name: "pant", val: 25, toolTip: "toolTip-pant-25", drill: false }, { name: "shirt", val: 28, toolTip: "toolTip-shirt-28", drill: false }, { name: "Tshirt", val: 33, toolTip: "toolTip-Tshirt-33", drill: false }, { name: "socks", val: 25, toolTip: "toolTip-socks-25", drill: false }, { name: "watchs", val: 40, toolTip: "toolTip-watchs-40", drill: false }, { name: "hats", val: 38, toolTip: "toolTip-hats-38", drill: true }] }, { category: "2014-9-3", subCategory: [{ name: "shoe", val: 25, toolTip: "toolTip-shoe-25", drill: false }, { name: "pant", val: 33, toolTip: "toolTip-pant-33", drill: false }, { name: "shirt", val: 37, toolTip: "toolTip-shirt-37", drill: false }, { name: "Tshirt", val: 38, toolTip: "toolTip-Tshirt-38", drill: false }, { name: "socks", val: 32, toolTip: "toolTip-socks-32", drill: false }, { name: "watchs", val: 28, toolTip: "toolTip-watchs-28", drill: true }, { name: "hats", val: 41, toolTip: "toolTip-hats-41", drill: false }] }, { category: "2014-12-4", subCategory: [{ name: "shoe", val: 22, toolTip: "toolTip-shoe-22", drill: false }, { name: "pant", val: 41, toolTip: "toolTip-pant-41", drill: false }, { name: "shirt", val: 33, toolTip: "toolTip-shirt-33", drill: false }, { name: "Tshirt", val: 22, toolTip: "toolTip-Tshirt-22", drill: false }, { name: "socks", val: 11, toolTip: "toolTip-socks-11", drill: false }, { name: "watchs", val: 39, toolTip: "toolTip-watchs-39", drill: false }, { name: "hats", val: 32, toolTip: "toolTip-hats-32", drill: false }] }, { category: "2015-3-5", subCategory: [{ name: "shoe", val: 33, toolTip: "toolTip-shoe-33", drill: false }, { name: "pant", val: 51, toolTip: "toolTip-pant-51", drill: false }, { name: "shirt", val: 43, toolTip: "toolTip-shirt-43", drill: false }, { name: "Tshirt", val: 43, toolTip: "toolTip-Tshirt-43", drill: false }, { name: "socks", val: 46, toolTip: "toolTip-socks-46", drill: false }, { name: "watchs", val: 47, toolTip: "toolTip-watchs-47", drill: false }, { name: "hats", val: 49, toolTip: "toolTip-hats-49", drill: false }] }];我想根据以下数组从这个数组中过滤subCategory 。
var arr = ["hats", "watchs"];因为我已经完成了以下操作，但它没有过滤

var arr = ["hats", "watchs"];
So for I have done following, but it is not filtering

最满意答案
您可以使用.filter来获取所需内容：
var filteredData = data.filter(function(topLevel) {
topLevel.subCategory = topLevel.subCategory.filter(function(bottomLevel) {
return arr.indexOf(bottomLevel.name) < 0;
})
return topLevel.subCategory.length;
});
演示：
You can use .filter to pull what you need:
var filteredData = data.filter(function(topLevel) {
topLevel.subCategory = topLevel.subCategory.filter(function(bottomLevel) {
return arr.indexOf(bottomLevel.name) < 0;
})
return topLevel.subCategory.length;
});
