jQuery would be better here:
jQuery 在这里会更好：
$('#one').click(function () { // on a click on the button with id 'one'
$('#two').trigger('click');// trigger the click on second, and go on
}
Using this method you can trigger events on other elements using an event on a particular element!
使用此方法，您可以使用特定元素上的事件触发其他元素上的事件！

you can use Jquery to bind an event to the click. and there do what you want:
您可以使用 Jquery 将事件绑定到单击。然后做你想做的：
$('#ButtonID').bind('click',function(){
$('#ButtonID2').show();
//or
$('#ButtonID1').removeAttr('disabled');//if you want it be shown but not enabled
});
this is for disableing the buttons:
这是用于禁用按钮：
$('#ButtonID').attr('disabled','disabled');
