Is this a right way to search names into JavaScript arrays?


By : Christian Mills
Date : October 16 2020, 06:10 AM
it helps some times You can use Array.filter and Array.includes like this:
code :
var students = [ { name: 'David', age: 12 }, { name: 'Daniel', age: 13 }, { name: 'Alex', age: 10 } ];

let searchByFirstName = str => students.filter(({name}) => name.includes(str))

console.log(searchByFirstName('Da'))
console.log(searchByFirstName('ex'))
console.log(searchByFirstName('iel'))
var students = [ { name: 'David', age: 12 }, { name: 'Daniel', age: 13 }, { name: 'Alex', age: 10 } ];

let searchByFirstName = str => students.filter(({name}) => name.startsWith(str))

console.log(searchByFirstName('Da'))
console.log(searchByFirstName('A'))

I think the issue was by ths following , If you don't want to include jQuery UI, you could try something like Better Autocomplete.

Dynamic Variable Names with JavaScript - Two arrays?

Hope that helps You need to create the object (or array depending on your needs) before you can add anything to it.
code :
window.userMarkers = {};

$.each($.parseJSON(window.usersArray), function (i, user) {
    window.userMarkers[user['id']] = L.marker(98.76, 12.34).addTo(map);
    console.log(window.userMarkers[user['id']]);
});

Javascript Creating Arrays with Unique Names with a for loop

it should still fix some issue I haven't heard of a doosy yet, but I think you'll need to instantiate a separate Eventarrayarray Array instance for each iteration:
code :
for (var f = 0; f < data.events.event.length; f++) {
  if (data.events.event[f].hasOwnProperty('title')) {
    var Eventarrayarray = new Array();

    Eventarrayarray["marker"] = marker[f];
    ...

    Eventarray[f] = Eventarrayarray;
}
for (var f = 0; f < data.events.event.length; f++) {
  if (data.events.event[f].hasOwnProperty('title')) {
    Eventarray[f] = {
      marker: marker[f],
      ...
    };
}

Accessing variable names of Javascript arrays

To fix this issue data[0][1] returns {name: "john"}. You can then use the Object.keys function that will return the keys of an object. It will return ['name']. Then you just have to get the first item of this array.
code :
const data = [["0", {name: "john"}], ["1", {surname: "white"}]];

console.log(Object.keys(data[0][1])[0]);
console.log(Object.keys(data[1][1])[0]);

Need Help Declaring Arrays with Different Names, JavaScript

seems to work fine Generally (i.e. in almost any programming language) dynamically creating variable names like that is discouraged and not really possible (short of using eval). Why not just use an array?
Before your top-level loop, create an array that is to contain the strVect arrays:
