使用javascript按下按钮时如何打开一个窗口并关闭另一个窗口？

Question

I am in quite a bind right now! You will notice in the Demo provided below that when you click the black button a window appears with another button in it. What I am trying to achieve is when you click the light gray button it will shut that whole window from the black button and open a whole new window! Below I will have some code and a demo!

HTML

<div id="sidemenu">
<div id="regionsContainer">
    <div id="regionsUnitedStates" class="not-open regionsButton">
    <div id="regionsUnitedStatesTooltip"></div>
    </div>
    <div id="regionsCanada" class="not-open regionsButton">
     <div id="regionsCanadaTooltip"></div>
    </div>
</div>
<div id="regionsUnitedStatesChooseState" class="regionsContent">
    <div id="chooseStateUnitedStatesColumnOne">
            <div id="chooseStateAlabama"></div>
    </div>
</div>
<div id="regionsCanadaChooseProvince" class="regionsContent">CDN</div>

CSS

#sidemenu {

    cursor:pointer;
}

Javascript

$(function(slideSidemenu) {
    setTimeout(function() { $("#sidemenu").addClass("show") }, 500);
});

var $regionsContent = $('.regionsContent'), 
$regionsButton = $('.regionsButton').click(function(){
    var $button = $(this).removeClass('not-open');
    var buttonIndex = $regionsButton.index($button);
    $regionsContent.removeClass('show').eq(buttonIndex).addClass('show');
    $regionsButton.not($button).addClass('not-open');
});

Answer 1

Is this what you are looking for? http://jsfiddle.net/4Lbhk/4/

I added a timeout before showing the other page:

setTimeout(function() {

    $regionsContent.eq(buttonIndex).addClass('show');
}, 300);

Answer 2

I am not sure of your question, but if you want to close the window from within the inside grey div, you could do:

$("#chooseStateAlabama").click(function(){
    $('.regionsContent').removeClass('show');
});

If you want to open another page in the whole page, something like this?

$("#chooseStateAlabama").click(function(){
    window.open("http://stackoverflow.com/","_self","");
});
