jquery实现搜索框从中间向两边扩展(左右放大)
显示效果:
隐藏效果:
前端核心代码如下:
<div class="search-icon col-md-2 col-sm-2 col-xs-4 col-md-offset-5 col-sm-offset-5 col-xs-offset-4"> <img src="../status/images/search.png" alt=""> </div> <div class="search-input row"> <div class="search-show col-md-6 col-sm-10 col-xs-10 col-md-offset-3 col-sm-offset-1 col-xs-offset-1"> <div class="input row"> <input type="text" class="col-md-9 col-sm-9 col-xs-9" placeholder="请输入你想了解的内容"> <div class="search-btn col-md-3 col-sm-3 col-xs-3"> <div class="search-name">搜索</div> <!-- <img src="../status/images/search.png" alt="" style="" /> --> </div> </div> </div> </div>
css就不在这里显示了,可以自己定义
下面就来说说jquery如何实现效果
显示
$('.search-icon').fadeOut(0,()=>{ $('.search-input').fadeIn().css({'width':'0%','position':'absolute','left':'50%'}).animate({ 'width':'100%', 'margin-left':'-50%' },500,'linear',()=>{ $('.input').fadeIn(500) }) })
隐藏
$('.input').fadeOut(700,function(){ $('.search-input').animate({ 'width':'0%', 'margin-left':'0%' },700,'linear',()=>{ $('.search-icon').fadeIn(700) }) })
方法说明:
fadeOut | 隐藏 |
fadeIn | 显示 |
animate | 动画 |
