我正在尝试使用contains进行过滤。但不起作用。任何人都可以在这里找到问题。
const nestedFilter = (targetArray, filters) => {
var filterKeys = Object.keys(filters);
return targetArray.filter(function(eachObj) {
return filterKeys.some(function(eachKey) {
return eachObj[eachKey].includes(filters[eachKey]);
});
});
};
let filter1 = {Id: "24", Name: "Api Gateway"};
let products = [

答案 0 :(得分：0)
您在控制台中遇到以下错误：
eachObj [eachKey] .includes不是函数
出现此错误是因为每个对象中的值之一在您的数组中为Number类型。代码String.prototype.includes()中使用的方法适用于String类型，不适用于Number类型，并且会抛出上述错误。
要解决此问题，您需要先使用Number上可用的.toString()方法将Number.ptototype类型的值转换为字符串，然后再使用.includes()：
let filter = {Id: "24", Name: "Api Gateway"};
let data = [{
"Id": 100024,
"Name": "Api Gateway UpdateXX",
"Description": "Course 0002 for Albanian literature",
"CreatedBy": "B, Mohamedarif (Cognizant)",
"CreatedDate": "2019-21-17T06:35:20.107Z"
}, {

"Description": "stridfgdfgng",
"CreatedBy": "Script",
"CreatedDate": "2019-04-17T06:35:20.107Z"
}];
let resultBy = (targetArr, filterObj) => {
let keys = Object.keys(filterObj);
return targetArr.filter(
o => keys.every(key => o[key].toString().includes(filterObj[key]))
);
};
console.log(resultBy(data, filter));
