Here is a example without knowing more of your code:
$(function () {
$('input:checkbox').click(function () {
$(this).prop('disabled', true);
var iName = this.name;
$.ajax({
url: "file.php",
data: {
'inputname': iName
},
success: function (data) {
alert(data.returned_val);
}
})
})
})

If you want to reach the input via name directly you need to use double backslasshes to escape the square brackets and reach that input via name. Use:
$('input[name=aisis_options\\[package_Aisis-Related-Posts-Package-master\\]]')
