How do I filter the word "mango" in an array from an object that contains, please? Example "mango"
var myIteams= [
{
title: "Title One",
section: 1,
tag: ["orange", "apple", "banana", "mango"]
},
{
title: "Title Two",
section: 15,
tag: ["mango"]
},
{
title: "Title Three",
section: 21,
tag: ["orange", "apple" ]
},
]
Just use Array.prototype.filter to filter the array with callback. Then use Array.prototype.includes to match the right item.
var myItems = [
{
title: "Title One",
section: 1,
tag: ["orange", "apple", "banana", "mango"]
},
{
title: "Title Two",
section: 15,
tag: ["mango"]
},
{
title: "Title Three",
section: 21,
tag: ["orange", "apple" ]
},
];
const match = myItems.filter(item => {
return item.tag.includes('mango');
});
console.log(match);
You can use Array.filter for this. It takes a function which should return something either 'truthy' or 'falsey'. If it returns something truthy, it keeps the item, otherwise it is filtered out.
var myIteams= [
{
title: "Title One",
section: 1,
tag: ["orange", "apple", "banana", "mango"]
},
{
title: "Title Two",
section: 15,
tag: ["mango"]
},
{
title: "Title Three",
section: 21,
tag: ["orange", "apple" ]
},
]
const result = myIteams.filter(item => item.tag.indexOf('mango') > -1)
console.dir(result)You can use filter to filter the array and some to find a tag list, which contains your desired value.
var myItems = [{
title: "Title One",
section: 1,
tag: ["orange", "apple", "banana", "mango"]
},
{
title: "Title Two",
section: 15,
tag: ["mango"]
},
{
title: "Title Three",
section: 21,
tag: ["orange", "apple"]
},
]
const filtered = myItems.filter(o => o.tag.some(t => t === 'mango'));
console.log(filtered);You can use filter and includes to get elements which contains tag 'Mango' in it
Filter: Filter provides new array where we get elements from existing array with some condition.
includes: It is used to determines wheter array includes certain element or not. It returns
trueorfalse
var myIteams= [
{
title: "Title One",
section: 1,
tag: ["orange", "apple", "banana", "mango"]
},
{
title: "Title Two",
section: 15,
tag: ["mango"]
},
{
title: "Title Three",
section: 21,
tag: ["orange", "apple" ]
},
];
var result = myIteams.filter(x => x.tag.includes("mango"));
console.log(result);You can use the filter method with an includes method in it. Here's an example of creating a function that lets you pass in what item you want to find.
var myItems = [
{
title: "Title One",
section: 1,
tag: ["orange", "apple", "banana", "mango"]
},
{
title: "Title Two",
section: 15,
tag: ["mango"]
},
{
title: "Title Three",
section: 21,
tag: ["orange", "apple" ]
},
];
function findItem(itemToFind) {
return myItems.filter(item => item.tag.includes(itemToFind));
}
console.log(findItem('mango'))
