Question

我目前正在使用Bootstrap创建一个网站，问题是在响应式小显示菜单上我希望将搜索输入显示在其他内容上，但我没有这样做。我正在使用jQuery。

预期的用途是，当按下搜索图标按钮时，它会显示隐藏的输入，而不是其他元素的全尺寸可用，再次单击按钮并使其消失，但如果不给予我，我无法想办法表单的宽度为100％，但它会使布局崩溃。我正在连接一个jsfiddle以启发它。此按钮和表单仅在小分辨率下可见。

的Javascript

$('#form-search button').click(function(){
        $(this).css({
            'border-top-left-radius':'0',
            'border-bottom-left-radius':'0'
        }).addClass('active');
        $('#form-search').css('width','100%');
        $('#form-search .form-control').css({
            'display':'inherit',
            'width':'100%',
        });
    });

CSS

#form-search{
border: none;
margin-top: -2px;
margin-right: -0.5em;
width:4.8em;
z-index: 6;
}
#form-search .form-control{
    display:none;
    z-index: 100;
}
#form-search .input-group-btn button{
    border-top-left-radius:4px;
    border-bottom-left-radius: 4px;
}
#navi-btn{
    margin-top: 8px;
    margin-right: 0.5em;
    z-index: 1;
}
#colapsador{
    margin-right: 0.5em;
    z-index: 1;
}

z-index属性似乎不起作用，如果有人可以启发我如何恢复原始css属性再次单击按钮会很好，但这不是我主要关注的问题，我可以搜索它。 / p>

Answer 1

<强> Updated fiddle

我不确定但是尝试将width从100％更改为50％：

$('#form-search').css('width','50%');

我认为解决问题，希望这有帮助。

Answer 2

z-index属性似乎无法正常工作

对于z-index，您需要在要在其上设置z-index的每个元素上使用position:absolute

Answer 3

我终于做到了，只是细微的细节，动画仍然缺失，但这完美无缺：）
