How to simulate this PHP function in jQuery?

Question

The function below made in PHP will return me an array where the searched word fits, as I can do the same though with jQuery?

$meuArrayMultidimensional = array(array("campo" => "teste"), array("campo" => "valor qualquer"), array("campo" => "teste"));
$search = "uma palavra qualquer";
$retorno = array_keys(
    array_filter(
    $meuArrayMultidimensional,
        function ($value) use ($search) {
            return (stripos($value['colunaDoArray'], $search) !== false);
        }
    )
);

Answer 1

If the goal is to filter to get the field later, you can use the array.filter() -- if it is to take the index, you can use the array.forEach()

the equivalent of stripos is "string".indexOf() and you can’t hit against false because he returns 0 if the index found is at position 0 of the string. you can also use the search - if you need to use Regex (Pex "hello world".search(/\sworld/i))

To iterate over an object, you can iterate through its keys with the Object.keys():

var objectoMultidimensional = {'0':{campo: 'teste'},'1':{campo: 'valor qualquer'}, '2':{campo: 'teste'}}
var result3 = [], objecto;
Object.keys(objectoMultidimensional).forEach(function(key, index) {
   objecto = objectoMultidimensional[key]; 
   if (objecto.campo.indexOf(search) > -1) {
       result3.push(objecto)
   }
});

console.log(result3)

you can still use the Object.values allied with the array.filter if the browser supports it (or if you are using a Shim):

var result4 = Object.values(objectoMultidimensional).filter(function(objecto) { 
    return objecto.campo.indexOf(search) > -1 
})

console.log(result4)

How do you notice, Object.values() returns an array with the values within the given object, instead of Object.keys() only returns keys from it.

To do the same with the search() that I talked about:

var search = 'TESTE';
var regExp = new RegExp(search, 'i');
var resultado = ['olá', 'mundo', 'teste'].filter(function(text) { return text.search(regExp) > -1 });
console.log(resultado);
