如何使按钮在单击时保持向下或向上状态，然后在再次单击时恢复到向上状态？

【问题讨论】：

它是 Flash 组件按钮、从 simpleButton 类扩展的按钮，还是您自己制作的全新按钮？

【解决方案1】：

import flash.events.Event;

var clicked = false; //Make a variable that stores the current state.

button_mc.addEventListener(MouseEvent.CLICK, toggleState);

function toggleState(e:Event){
    clicked = !clicked; //Toggle the current state

    (clicked) ? button_mc.gotoAndPlay(2) : button_mc.gotoAndPlay(1);
    //if clicked is true, go to the clicked frame in the button
    //(you might have flags, in which case, name them in quotes, 
    //butt_mc.gotoAndPlay("clicked")), otherwise go to the first 
    //frame (which should be the upstate)
}
