输入字段中键盘输入的处理
通过WSEV_KEY_HOOK触发器的事件处理,对输入字段中键盘输入进行处理。# WSEV_KEY_HOOK触发器的事件处理例 # 设置WSEV_KEY_HOOK触发器 ... def hookop(object): # 获取键盘码 key = mpfc.WSGIappKeyboard().getKey(); if ((key >= mpfc.WSK_0 and key <= mpfc.WSK_9 ) or (key >= mpfc.WSK_KP_0 and key <= mpfc.WSK_KP_9) or key == mpfc.WSK_plus or key == mpfc.WSK_minus or key == mpfc.WSK_BackSpace or key == mpfc.WSK_Delete or key == mpfc.WSK_Insert or key == mpfc.WSK_space or key == mpfc.WSK_Up or key == mpfc.WSK_Down or key == mpfc.WSK_Left or key == mpfc.WSK_Right or key == mpfc.WSK_Return ): # 只接受关心的键盘输入 return; # 屏蔽其他键盘输入 mpfc.WSGIappKeyboard().setKey(0); return mpfc.WSGFfunctionRegister("hookop",hookop)上述的例子中,只接受数字输入。通过键盘对象的getKey()函数获得当前的键盘输入码。 通过 setKey(0) 函数将不需要的输入内容删除。
