JavaScript checkbox checked not working

Question

Code :

var str = '2,4';
var accept_message = str.split(',');


var accept_message_html = '';
var accpet_message_Obj = {
    1: 'Friends',
    2: 'Models',
    3: 'Premiums',
    4: 'Basics'
};
$.each(accpet_message_Obj, function(key, value) {
    accept_message_html += '<span style="padding-right:30px;"><input style="float:none;" type="checkbox" name="privacy_options[]"' + (key == accept_message[key] ? ' checked="checked"' : '') + ' value="' + key + '" /> ' + value + '</span>\n';
});

$('#content-area').html(accept_message_html);

Above coding not working. I need to checkbox checked which values are 2 and 4 but there is no checkbox selected. :(

You need use indexOf() to check if key exists in accept_message

The indexOf() method returns the first index at which a given element can be found in the array, or -1 if it is not present.

Code

accept_message.indexOf(key) > -1

DEMO

However, as indexOf() is supported in IE9+, You can use $.inArray()

Search for a specified value within an array and return its index (or -1 if not found).

Code

$.inArray(key, accept_message) > -1
