Jquery Validation for Dynamically Created Fields

Question

I have basic javascript code to generate input text areas as below

$(\"#btnAdd\").click(function (e) {
        var itemIndex = $(\"#container input.iHidden\

You could use the .rules('add') method immediately after the new input element is created...

$("#btnAdd").click(function (e) {
    var itemIndex = $("#container input.iHidden").length;
    e.preventDefault();
    var newItem = $("<span class='badge badge-success'>" + itemIndex + "</span> <input id='Interests_" + itemIndex + "__Id' type='hidden' value='' class='iHidden'  name='Interests[" + itemIndex + "].Id' /><input type='text' id='InvoiceNumber_" + itemIndex + "__InvoiceNumber' placeholder='Fatura Numarası' name='[" + itemIndex + "].InvoiceNumber'/>    <input type='text' id='Interests_" + itemIndex + "__InterestText' placeholder='Fatura Tutarı(TL)' name='[" + itemIndex + "].Amount'/> <br /><br />");
    $("#container").append(newItem);

    // add the rules to your new item
    $('Interests_' + itemIndex + '__Id').rules('add', {
        // declare your rules here
        required: true
    });
});

Alternatively, for a simple rule like required, you could just add the required="required" attribute to the new element when you create it...

$("#btnAdd").click(function (e) {
    var itemIndex = $("#container input.iHidden").length;
    e.preventDefault();
    var newItem = $("<span class='badge badge-success'>" + itemIndex + "</span> <input id='Interests_" + itemIndex + "__Id' type='hidden' value='' class='iHidden'  name='Interests[" + itemIndex + "].Id' /><input type='text' id='InvoiceNumber_" + itemIndex + "__InvoiceNumber' placeholder='Fatura Numarası' name='[" + itemIndex + "].InvoiceNumber'/>    <input type='text' id='Interests_" + itemIndex + "__InterestText' placeholder='Fatura Tutarı(TL)' name='[" + itemIndex + "].Amount' required='required' /> <br /><br />");
    $("#container").append(newItem);
});
