javascript - 在 GWT 中删除 StoreFilterField 的焦点样式

Question

我正在寻找一些方法来删除 StoreFilterField 的 x-form-foucs css 样式.

我在 formPanel 上放置了一个 storeFilterFiled 和其他一些文本字段，如果我想在文本字段中输入一些单词，在我单击文本字段后光标将返回到 storeFilterField，因为 storeFilterField 将始终获得焦点。

已尝试使用 removeStyleName("x-form-focus");，但不起作用。

更新:

在获得 Tangent 建议后，我使用了 chrome 开发人员工具并在 StoreFilterField 的属性修改上中断。当我点击其他字段时，我得到了调用堆栈。

堆栈如下:

com_extjs_gxt_ui_client_core_El_$removeStyleName

已由 com_extjs_gxt_ui_client_widget_form_TriggerField_$triggerBlur 调用，删除的样式名称为“x-trigger-wrap-focus”，TriggerField 已由 StoreFilterField 扩展。

triggerBlur() 由 TriggerField_$mimicBlur 调用。 mimicBlur() 被调用

focusEventPreview = new BaseEventPreview() {
  protected boolean onAutoHide(final PreviewEvent ce) {
    if (ce.getEventTypeInt() == Event.ONMOUSEDOWN) {
      mimicBlur(ce, ce.getTarget());
    }
    return false;
  }
};

在 TriggerField 的 onRender() 中

整个堆栈如下:

感谢任何帮助。

我终于找到了注意事项。那就是我同时使用了 FormButtonBinding。 FormButtonBinding 将调用它绑定(bind)的面板中每个字段的 isValid()。 StoreFilterField 的 isValid 将始终执行 onFilter() 和 focus()...

只需重写 isValid() 如下代码:

    filter = new StoreFilterField<Model>()
    {
        @Override
        public boolean isValid(boolean preventMark) {
            if (disabled) {
                return true;
            }
            boolean restore = this.preventMark;
            this.preventMark = preventMark;
            boolean result = validateValueWithOutOnFilter(getRawValue());
            if (result) {
                //activeErrorMessage = null;
            }
            this.preventMark = restore;
            return result;
        }

        protected boolean validateValueWithOutOnFilter(String value) {
            ...
        }

        @Override
        protected boolean doSelect(Store<Model> store, Model parent, Model record, String property, String filter)
        {
            ...
        }
    };
