JavaFx：如何验证在运行时创建的多个文本字段？
我在运行时使用for循环创建多个文本字段，并将它们添加到Gridpane内部（有8列），如下所示：JavaFx：如何验证在运行时创建的多个文本字段？,java,javafx,javafx-2,javafx-8,Java,Javafx,Javafx 2,Javafx 8,我在运行时使用for循环创建多个文本字段，并将它们添加到Gridpane内部（有8列），如下所示： public static GridPane table(int rows){ GridPane table = new GridPane(); for(int i=0; i<rows; i++){ JFXTextField textField1 = new JFXTextField(); te

对于（int i=1；i您的绑定逻辑是正确的。但是，问题是由于for循环的导致的（int i=1；i什么是JFXTextField
？为什么不使用TextField
@Yahya Learn google fu这会很快让人想到，它是一个控件，使用它基本上是一种设计选择。虽然在这种情况下，它只会使描述变得比必要的更复杂……它解决了我的问题，感谢您的解释在上，Merci@Yahya:）另一件事@Yahya如果在选项卡B中我有另一个表，比如说，另一个容器中的TableA带有TextField复选框，并且按钮也依赖于此TableA的验证，那么我必须为其创建单独的方法，或者我可以使用类似这样的方法：private void validateTable（网格窗格表格、网格窗格表格A、按钮）
@Junaid如果TableA
是一个GridPane
并且包含TextFields
，你完全可以对这个表使用相同的方法。好的@Yahya但是TableA不在同一个GridPane中，它在不同的GridPane中。所以我试着像你说的那样做，但问题是当表的所有条目都被验证时，它会被嵌入最近在不检查不同网格窗格中的TableA条目的情况下启用按钮（问题）。因此，在所有这些之后，当我单击TableA字段时，它将再次禁用按钮，直到TableA条目验证。但我希望程序应验证Table和TableA（两者都在不同的网格窗格中）然后逐个启用按钮。如果你不明白我想说的话，我会更新我的问题。@Yahya你能现在检查一下吗。
