使用jQuery Validate插件添加元素后验证表单

Question

我已经阅读了有关该主题的其他主题但无法使其正常工作：s

我在表格中有一个表格，我可以动态添加更多行。

$( "#addLinha" ).click(function() {
   $('#addForNew tr:last').after(rowTemp);
   $('#addForNew tr:last').rules("add", "required");
});

但验证器不会使用这些行来验证：s

<table id="addForNew" class="ink-table bordered">
    <thead>
        <tr>
            <th class="fornecedoresTable">Fornecedor</th>
            <th class="fornecedoresTable">Marca</th>
            <th class="fornecedoresTable">Modelo</th>
            <th class="fornecedoresTable">Preço</th>
            <th></th>
        </tr>
    </thead>
    <tr >
        <td class="fornecedoresTable">
            <div class="control validation">
                <input type="hidden" name="addMaterialFornecedor[]" id="addMaterialFornecedorHide"><input type="text" name="" class="" value="" id="addMaterialFornecedor" > 
            </div>
        </td>
        <td class="fornecedoresTable">
            <div class="control validation">
                <input type="hidden" name="addMaterialFabricante[]" id="addMaterialFabricanteHide"><input type="text" name="" class="" value="" id="addMaterialFabricante" > 
            </div>
        </td>
        <td class="fornecedoresTable">
            <div class="control validation">
                <input type="hidden" name="addMaterialModelo[]" id="addMaterialModeloHide"><input type="text" name="" class="" value="" id="addMaterialModelo" >
            </div>
        </td>
        <td class="fornecedoresTable">
            <div class="control validation">
                <input type="text" name="addMaterialPreco[]" class="price ink-fv-custom custom-price" value="" id="addMaterialPreco" >
            </div>
        </td>
        <td class="fornecedoresTable" name="teste[]"><button type="button" class="ink-button" id="removeLinha" style="margin: 0px;"><i class="icon-remove-sign icon-large"></i></button></td>
    </tr>
</table>

Answer 1

您的代码：

$('#addForNew tr:last').rules("add", "required");

  

“但验证程序不会使用该行来验证”

因为您无法验证行。您无法向tr元素添加规则。

jQuery Validate插件仅适用于表单字段元素，因此您只能向input，select和textarea元素添加规则。

您的代码应该更像这样：

$('#addForNew tr:last input').rules("add", "required");

Answer 2

使用$（“selector”）。on（）jQuery方法。 读： http://api.jquery.com/on/

请记住，选择器不必是ID，因为它是一个唯一的html元素，并且您正在尝试引用未来的表行。
