我有一个包含3列的Twitter Bootstrap布局。中间的colomn无法切换，但左右列可以隐藏和显示。当左栏被隐藏时，我可以怎样才能做到这一点，中间的一栏一直跨越，依此类推。
因此，如果我有一个 3 6 3 网格，并且我隐藏了左列，它就变成了 6 3 网格。我怎么能使用jquery使它自动将跨度更改为 9 3 以便填充页面？
我尝试用jquery更改属性但是我无法使用它，我在jquery中不太了解。
这是我的代码：

我认为这会做你想要的。
切换到9 + 3：
$('#left').removeClass('span3').addClass('hidden');
$('#middle').removeClass('span6').addClass('span9');
切换回来：
$('#right').removeClass('span9').addClass('span6');
$('#left').removeClass('hidden').addClass('span3');

这不是动画，但应该有效：
$(document).ready(function(){
$("#lefttoggle").click(function(){
$("#left").toggle(1000);
if($('#middle').hasClass('span6')){
$('#middle').removeClass('span6').addClass('span9');
}
else{
$('#middle').removeClass('span9').addClass('span6');
}
});
$("#righttoggle").click(function(){
$("#right").toggle(1000);
if($('#middle').hasClass('span6')){
$('#middle').removeClass('span6').addClass('span9');
}
else{
$('#middle').removeClass('span9').addClass('span6');
}
});
});
