Error after insert HTML code in DOM in console (Chrome browser)

Question

Get HTML in line: room["html"] = $(this).parents(".selectRowRoom").html(); and insert after load step-02.php in .thisRoom but this error is in Console.

$(function () {
var hotel = [];
var lenHotel = 0;
$('#forPrice').on('click', function() {
    $('select').each(function() {
        if($(this).val() > 0 && $(this).val() < 10) {
            var room = {};
            room["room"] = $(this).attr('room');
            room["price"] = $(this).attr('price');
            room["val"] = $(this).val();
            room["html"] = $(this).parents(".selectRowRoom").html();

            hotel.push(room);
        }
    });
    lenHotel = Object.keys(hotel).length;
    console.log(hotel);
});

$('#forPrice').click(function () {
    $('#Step-01').hide();
    $('#Step-02').show();
    $('.hiddenAndShow').hide();
    $( "#Step-02" ).load( 'step_02', function () {
        for(var i = 0; i <= lenHotel; i++) {
            $("#Step-02").find('.thisRoom').append("<tr class=\"selectRowRoom\">");
            $("#Step-02").find('.thisRoom').append(hotel[i]['html']);
            $("#Step-02").find('.thisRoom').append("</tr>")
        }
    });
});
})

And error in console is:

Uncaught TypeError: Cannot read property 'html' of undefined

Answer 1

This...

 for(var i = 0; i <= lenHotel; i++) 

Should be this

for(var i = 0; i < lenHotel; i++) 

Your accessing an element in the array that doesnt exist.
