动态创建字段的Jquery验证

我有基本的javascript代码来生成输入文本区域,如下所示

$("#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);
    });

我有一个动态字段的表单。我正在为其他元素使用jquery验证器。现在我还要验证这个动态创建的字段。

对于静态字段,我的工作验证脚本。

  $('#frm_register').validate({

        focusInvalid: false,
        ignore: "",
        rules: {
            FirstName: {
                required: true
            } ....

这里是我动态字段的示例。

<input type="text" id="InvoiceNumber_0__InvoiceNumber" placeholder="Fatura Numarası" name="[0].InvoiceNumber">
<input type="text" id="Interests_0__InterestText" placeholder="Fatura Tutarı(TL)" name="[0].Amount"> 
<input type="text" id="InvoiceNumber_1__InvoiceNumber" placeholder="Fatura Numarası" name="[1].InvoiceNumber">
<input type="text" id="Interests_1__InterestText" placeholder="Fatura Tutarı(TL)" name="[1].Amount">

您可以在创建新输入元素后立即使用the .rules('add') method ...

$("#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
    });
});

或者,对于像required这样的简单规则,您可以在创建新元素时将required="required"属性添加到新元素中...

$("#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);
});
