警报确认，javaFx
我在做这个任务，我做了一个组合框，里面装满了百吉饼，另一个装满了奶油奶酪，为了添加或删除项目，必须选择一个单选按钮。除了这一部分，我几乎什么都要做。如果我单击“是”，它将删除，如果我单击“否”，它将不会删除项目。当我单击“否”时，它会起作用。它不会删除，并且一切正常。但是，当我单击“是”“删除”时，警报会一直保持，直到我再次按“否”为止。 我正在使用JavaFx14警报确认，javaFx,java,javafx,Java,Javafx,我在做这个任务，我做了一个组合框，里面装满了百吉饼，另一个装满了奶油奶酪，为了添加或删除项目，必须选择一个单选按钮。除了这一部分，我几乎什么都要做。如果我单击“是”，它将删除，如果我单击“否”，它将不会删除项目。当我单击“否”时，它会起作用。它不会删除，并且一切正常。但是，当我单击“是”“删除”时，警报会一直保持，直到我再次按“否”为止。 我正在使用JavaFx14 public int deleteItem() { int indexInteger = 0;
