我有一个 3 列的 Twitter Bootstrap 布局。中间列不能切换，但左右列可以隐藏和显示。我怎么可能做到这一点，所以当左栏被隐藏时，中间的栏会一直跨越等等。

因此，如果我有一个3 6 3网格并且我隐藏了左列，它就变成了一个6 3网格。我如何使用 jquery 使其自动将跨度更改为9 3以填充页面？

我曾尝试用 jquery 更改属性，但我无法让它工作，我对 jquery 不太了解。

这是我的代码：

        padding: 9px 0;
      }

      @media (max-width: 980px) {

        .navbar-text.pull-right {

我认为这将满足您的需求。

要切换到 9 + 3：

$('#left').removeClass('span3').addClass('hidden');
$('#middle').removeClass('span6').addClass('span9');

要切换回来：

$('#right').removeClass('span9').addClass('span6');
$('#left').removeClass('hidden').addClass('span3');

这不是动画，但应该可以：

$(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');
        }
    });
});
