打開上傳窗口中點擊菜單項

Question

我想通過點擊菜單項，打開從上傳元素uploadwindow。這可能嗎？ 另一個想法是在菜單欄添加上載元素，但我認爲這是不可能的，對不對？

感謝您的幫助！

Answer 1

也許一些JavaScript可以幫助你：

.v-slot-my-upload { 
    display: none; 
} 

Answer 2

菜單欄，菜單項，窗口和上載的最簡單的用例，布點是留給你：如果你想隱藏上傳

Upload upload = new Upload(); 
upload.setImmediate(true); // if you want to start upload after selection 
upload.addStyleName("my-upload"); 
MenuBar menuBar = new MenuBar(); 
menuBar.addItem("Caption", new Command() { 
    private static final long serialVersionUID = 1L; 

    @Override 
    public void menuSelected(MenuItem selectedItem) { 
     JavaScript.getCurrent().execute(
      "document.getElementsByClassName('gwt-FileUpload')[0].click()"); 
    } 
}); 
addComponent(upload); 
addComponent(menuBar); 

：

MenuBar menuBar = new MenuBar(); 
    final Window window = new Window(); 
    window.setContent(new Upload()); 
    menuBar.addItem("Caption", new Command() 
    { 
     @Override 
     public void menuSelected(MenuItem selectedItem) 
     { 
      UI.getCurrent().addWindow(window); 
     } 
    });
