输入必需属性在直接写在Body上时有效。生成检查时显示的新行必需属性但不适用于下一行元素。我试图说明这种情况。
对于以下图像，必填字段正在运行 Required field Working only for the first Row
但是当我按下Add按钮时，Next Rows Element Required Attribute不能像下面这样工作： For Next Any other Rows Element Required Attribute is not Working
以下是我的代码。

我的超文本中有人可以帮助解决错误吗？
答案 0 :(得分：1)
添加新行后，您需要重新初始化插件。这与HTML5 required属性无关。
只需检查DOC，您需要在添加功能的底部使用：
$('#testForm').validator('update');
