所以我创建了一个Java GUI应用程序,我有一个主窗体,我通过单击一个jbutton运行这个类PathBrowser,JFileChooser运行两次,我尝试从我的mainform添加opendialog所以我可以有相同的窗户上的标志。
这是我的代码:
public class PathBrowser {
public static String filepath = null;
public static void main(String[] args)
{
JButton select = new JButton();
JFileChooser browse = new JFileChooser();
//add the icon of main form for JFileChooser
//OPENS TWICE?! Error
browse.showOpenDialog(MainForm.frame);
//if blank goes to user/documents. Unsure about other OSes
browse.setCurrentDirectory(new java.io.File("C:/"));
browse.setDialogTitle("Browse Folder");
browse.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
//when clicked open (approve option)
if (browse.showOpenDialog(select) == JFileChooser.APPROVE_OPTION){
//folder has peen selected
MainForm.selfolder = true;
//add the path to the string filepath
filepath = (browse.getSelectedFile().getAbsolutePath());
System.out.println("The path for the server is: "+browse.getSelectedFile().getAbsolutePath());
//add the information to the textarea
MainForm.textArea.setText("The path for the server is: "+browse.getSelectedFile().getAbsolutePath());
}
}
}

你打电话给function enviando2(){
var formData2 = new FormData($(".formulario2")[0]);
var message2 = "";
return $.ajax({
两次,这就是为什么你得到它两次。
只需删除此行:
browse.showOpenDialog
要保留框架的图标,请替换
browse.showOpenDialog(MainForm.frame);
与
browse.showOpenDialog(select)
