Filter array of objects by multiple properties and values
提问by BarryWalsh
Is it possible to filter an array of objects by multiple values?
是否可以通过多个值过滤对象数组？
E.g in the sample below can I filter it by the term_ids 5 and 6 and type car at the same time?
例如，在下面的示例中，我可以通过 term_ids 5 和 6 过滤它并同时输入 car 吗？
[
{
"id":1,
"term_id":5,
"type":"car"
},
{
"id":2,
"term_id":3,
"type":"bike"
},
{
"id":3,
"term_id":6,
"type":"car"
}
]
Definitely up for using a library if it makes it easier.
绝对可以使用库，如果它更容易的话。

You can do it with Array.filter
你可以用Array.filter
var data = [{
"id": 1,
"term_id": 5,
"type": "car"
},
{
"id": 2,
"term_id": 3,
"type": "bike"
},
{
"id": 3,
"term_id": 6,
"type": "car"
}
];
var result = data.filter(function(v, i) {
return ((v["term_id"] == 5 || v["term_id"] == 6) && v.type == "car");
})
console.log(result)回答by Nenad Vracar
You can do this with plain js filter()method and use &&to test for both conditions.
您可以使用普通的 jsfilter()方法执行此操作，并用于&&测试这两种情况。
var data = [{"id":1,"term_id":5,"type":"car"},{"id":2,"term_id":3,"type":"bike"},{"id":3,"term_id":6,"type":"car"}];
var result = data.filter(function(e) {
return [5, 6].includes(e.term_id) && e.type == 'car'
});

The following function will help you out.
以下功能将帮助您。
nestedFilter = (targetArray, filters) => {
var filterKeys = Object.keys(filters);
return targetArray.filter(function (eachObj) {
return filterKeys.every(function (eachKey) {
if (!filters[eachKey].length) {
return true;
}
return filters[eachKey].includes(eachObj[eachKey]);
});
});
};
Use this function with filters described as below:
将此函数与如下所述的过滤器一起使用：
var filters = {
"id": ["3"],
"term_id": ["6"],
"type": ["car","bike"]
}
Dont pass empty array. If there are no values in the array, skip that property in the filters.
不要传递空数组。如果数组中没有值，则在过滤器中跳过该属性。
The result will be filtered array.
结果将被过滤数组。
