java确认对话框多次显示
我在addListSelectionListener中有一个确认对话框。当我在表中选择一行时,将触发此操作。然后出现“确认”对话框,单击“是”或“否”后,它会继续出现
这是我的密码
public Reference() {
initComponents();
fillTable();
jTable1.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
int prompt = JOptionPane.showConfirmDialog(null, "Are you sure you want to Check Out this item?", "Warning", JOptionPane.YES_NO_OPTION);
if (prompt == 0) {
String accessNo = jTable1.getValueAt(jTable1.getSelectedRow(), 0).toString();
String query = "delete from reference where accessNo=" + accessNo + "";
if (DB.executeNonQuery(query) > 0) {
JOptionPane.showMessageDialog(null, "Check out Successfull!");
fillTable();
} else {
JOptionPane.showMessageDialog(null, "Check out Failed!");
}
}
}
});
}
