how to validate the dynamic textboxes so that no two textboxes can contain same value

Logic

• Store all TextBox values in an Array
• Sort the Array
• Compare Consecutive values

Demo

var allTextBoxes = [];

$('input[type=text]').each(function () {
    allTextBoxes.push($(this).val())
});

var sorted_arr = allTextBoxes.sort();

for (var i = 0; i < allTextBoxes.length - 1; i++) {
    if (sorted_arr[i + 1] == sorted_arr[i]) {
        alert("Please enter different value in each TextBox.");
        return false;
    }
}
