过滤对象数组，其属性包含JavaScript中的值
假设我们有一个像这样的对象数组-
const arr = [{
name: 'Paul',
country: 'Canada',
}, {
name: 'Lea',
country: 'Italy',
}, {
name: 'John',
country: 'Italy',
}, ];我们需要设计一种根据字符串关键字过滤对象数组的方法。搜索必须在对象的任何属性中进行。
例如-
When we type "lea", we want to go through all the objects and all their properties to return the objects that contain "lea". When we type "italy", we want to go through all the objects and all their properties to return the objects that contain italy.
示例
为此的代码将是-
const arr = [{
name: 'Paul',
country: 'Canada',
}, {
name: 'Lea',
country: 'Italy',
}, {
name: 'John',
country: 'Italy',
}, ];
const filterByValue = (arr = [], query = '') => {
const reg = new RegExp(query,'i');
return arr.filter((item)=>{
let flag = false;
for(prop in item){
if(reg.test(item[prop])){
flag = true;
}
};
return flag;
});
};
console.log(filterByValue(arr, 'ita'));输出结果
控制台中的输出将是-
[
{ name: 'Lea', country: 'Italy' },
{ name: 'John', country: 'Italy' }
