问题描述

导航栏折叠时，我希望搜索栏可见.

我的代码:

我用第一种方法，您可以在此处找到 jsfiddle

完整代码:

 < header class ="blog-masthead">< nav class ="navbar" role ="navigation">< div class ="container">< div class ="navbar-header">< button type ="button" class ="navbar-toggle折叠的向左拖动" data-toggle ="collapse" data-target =#navbar-collapse">< span class ="sr-only">切换导航</span>< span class ="icon-bar"></span>< span class ="icon-bar"></span>< span class ="icon-bar"></span></button>< form class ="navbar-form折叠的navbar-right" role ="search" action ="/search" method ="get">< div class ="form-group input-group">< input type ="text" class ="form-control input-sm" placeholder ="Search" id ="sitesearch" name ="query">< span class ="input-group-addon"><按钮type ="submit" class ="btn btn-default btn-xs">< span class ="glyphicon glyphicon-search"></span</button></span></div></form></div><！-导航栏标题->< div class ="collapse navbar-collapse" id ="navbar-collapse">< ul class ="nav navbar-nav navbar-left">< li>< a href ="/blog">博客</a></li>< li>< a href ="/about">关于</a></li></ul></div><！-导航栏折叠-></div></nav></header> 

I want to have my search bar visible when the navbar collapses.

My code: http://jsfiddle.net/edalzell/a3yng825/1/ works when collapsed but shows two search bars when expanded.

HTML:

<header class= "blog-masthead">
    <nav class="navbar" role="navigation">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed pull-left" data-toggle="collapse" data-target="#navbar-collapse">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <form class="navbar-form collapsed navbar-right" role="search" action="/search" method="get">
                    <div class="form-group input-group">
                        <input type="text" class="form-control input-sm" placeholder="Search" id="sitesearch" name="query">
                        <span class="input-group-addon"><button type="submit" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-search"></span></button></span>
                    </div>
                </form>
            </div> <!-- navbar-header -->
            <div class="collapse navbar-collapse" id="navbar-collapse">
                <ul class="nav navbar-nav navbar-left">
                    <li><a href="/blog">Blog</a></li>
                    <li><a href="/about">About</a></li>

                </ul>
            <form class="navbar-form navbar-right" role="search" action="/search" method="get">
                <div class="form-group input-group">
                    <input type="text" class="form-control input-sm" placeholder="Search" id="sitesearch" name="query">
                    <span class="input-group-addon"><button type="submit" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-search"></span></button></span>
                </div>
            </form>
            </div> <!-- navbar-collapse -->
        </div>
    </nav>
</header>

解决方案

That is because you have two search bars declared,you have a couple of options to get the desired result

1. Remove the extra searchbar that you have declared in the collapse section

2. Hide/show specific items on your desired resolution ,you can check this SO thread

I have used the first way ,you can find the jsfiddle here

Complete code:

<header class= "blog-masthead">
    <nav class="navbar" role="navigation">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed pull-left" data-toggle="collapse" data-target="#navbar-collapse">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <form class="navbar-form collapsed navbar-right" role="search" action="/search" method="get">
                    <div class="form-group input-group">
                        <input type="text" class="form-control input-sm" placeholder="Search" id="sitesearch" name="query">
                        <span class="input-group-addon"><button type="submit" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-search"></span></button></span>
                    </div>
                </form>
            </div> <!-- navbar-header -->
            <div class="collapse navbar-collapse" id="navbar-collapse">
                <ul class="nav navbar-nav navbar-left">
                    <li><a href="/blog">Blog</a></li>
                    <li><a href="/about">About</a></li>

                </ul>

            </div> <!-- navbar-collapse -->
        </div>
    </nav>
</header>
