Question

How could I do a search by name and surname with an array javascript?
and every time I search something that begins with je, div=result show me all Name and Surnames with Je in this case Jessica and Jey;
this would be a onkeydown event, right?

<input type='text' id='filter' placeholder='search in array'>

here I print the result:

<div id='result'></div>

this is my array :

var datos = [ ['Jessica','Lyn',3],
         ['Jhon','Cin',5],
         ['Alison','Peage',1],
         ['Thor','zhov',12],
         ['Jey','hov',32]  
        ];

Answer 1

var $result = $('#result');

$('#filter').on('keyup', function () {
    var $fragment = $('<div />');
    var val = this.value.toLowerCase();
    $.each(datos, function (i, item) {console.log( item[0].toLowerCase().indexOf(val) );
        if ( item[0].toLowerCase().indexOf(val) == 0 ) {
            $fragment.append('<p>' + item[0] + ' ' + item[1] + '</p>');
        }
    });
    $result.html( $fragment.children() );
});
