I have soo many nested arrays like this
[['branch',12,'name','cofee'],['state',15,'name','tea'],['Country',12,'name','tea']['branch',15,'name','Choclate']]
I want to filter array which is having the element branch so result ll be like this
[['branch',12,'name','cofee'],['branch',15,'name','Choclate']]
can anybody help me on this
You should provide a predicate to filter which checks if the array contains 'branch'.
If you can use ES6, I would do:
const data = [
['branch', 12, 'name', 'cofee'],
['state', 15, 'name', 'tea'],
['Country', 12, 'name', 'tea'],
['branch', 15, 'name', 'Choclate']
];
const processed = data.filter(d => (d.indexOf('branch') > -1));
console.log(processed);If you can't use ES6:
const data = [
['branch', 12, 'name', 'cofee'],
['state', 15, 'name', 'tea'],
['Country', 12, 'name', 'tea'],
['branch', 15, 'name', 'Choclate']
];
const processed = data.filter(function (d) {
return d.indexOf('branch') > -1;
});
console.log(processed);You are missing a comma in your array. You are dealing with a 2d array, a simple object to work with really. Just use a for loop looking for item [0] in each array.
var div = document.createElement("div");
var myArray = [['branch',12,'name','cofee'],['state',15,'name','tea'],['Country',12,'name','tea'],['branch',15,'name','Choclate']];
var filteredArray = [[]];
for (var i = 0; i < myArray.length; i++) {
if(myArray[i][0] === 'branch'){
filteredArray.push(myArray[i]);
}
}
var t = document.createTextNode(filteredArray);
div.appendChild(t);
document.body.appendChild(div);Well a modern approach is ;
var data = [['branch',12,'name','cofee'],['state',15,'name','tea'],['Country',12,'name','tea'],['branch',15,'name','Choclate']],
filtered = data.filter(f => f.includes("branch"));
console.log(filtered);
