jquery - 滑出 TextField 焦点推送内容并丢失转换

Question

所以，我目前正在一个网站上练习网络开发，但遇到了一些小问题。我希望能够单击图像“搜索图标”，然后让我的文本字段滑出，它确实如此，但它没有聚焦并准备好供用户输入。当我添加焦点事件时它起作用了，但它失去了过渡并将我在导航支架中的其他内容推到一边一秒钟，然后又回来了。我很困惑为什么会这样，我希望得到一些帮助来解决我的问题并更好地理解它。

这是我的 HTML:

<header>
    <div class="nav-holder">
        <nav>
            <ul>
                <li><a class="active" href="index.html">HOME</a></li>
                <li><a href="#">WORK EXPERIENCE&nbsp;&nbsp;<span class="one"></span><span class="two"></span></a>
                    <ul>
                        <li><a href="#">WEB DEVELOPEMENT</a></li>
                        <li><a href="#">IT SUPPORT</a></li>
                    </ul>
                </li>
                <li><a href="#">INTRODUCING ME</a></li>  
                <li><a href="#">CONTACT INFORMATION</a></li>
            </ul>


        </nav>

        <form method="post" action="">
            <input id="search-box" type="text" name="search" placeholder="Search...">
        </form>

        <img id="search-icon" src="img/searchicon.png"/>

        <div class="clear"></div>
    </div>

</header>

这是我的 CSS:

    * {
    margin: 0;
    padding: 0;

.nav-holder {
    position: fixed;

    opacity: 1;
    z-index: 2;
    transform: translateY(0%);
    transition-delay: 0s, 0s, 0.3s;
}

nav ul li ul li {
    float: none;
}

.one {
    display: inline-block;
    background-color: dimgrey;
    height: 1px;
    width: 7px;
    transform: rotate(55deg);
    margin-left: -3px;
    margin-bottom: 4px;
}

.two {
    display: inline-block;
    background-color: dimgrey;
    height: 1px;
    width: 7px;
    transform: rotate(125deg);
    margin-left: -3.2px;
    margin-bottom: 4px;
}

#search-icon {
    float: right;
    max-height: 18px;
    height: 100%;
    max-width: 18px;
    width: 100%;
    cursor: pointer;
    margin-top: 11px;
    margin-right: 7px;
}

#search-box {
    width: 200px;
    box-sizing: border-box;
    transition: all ease-in-out .3s;
    position: relative;
    float: right;
    margin-top: 9px;
    margin-right: -200px;
    line-height: 22px;
    border: none;
    outline: none;
    background-color: black;
    opacity: .8;
}

#search-box:focus {
    caret-color: lightgrey;
    color: lightgrey;
}

#search-box.active {
    margin-right: 0;
}

@-webkit-keyframes autofill {
    to {
        color: lightgrey;
        background: transparent;
    }
}

input:-webkit-autofill {
    -webkit-animation-name: autofill;
    -webkit-animation-fill-mode: both;
}

.clear {
    clear: both;
}

这是我的 JQuery:

    $(document).ready(function () {
    $('html').on('click', function (e) {
        if (e.target.id == 'search-icon') {
            $('#search-box').toggleClass('active');
            $('#search-box').focus();
        }
        else if (e.target.id == 'search-box') {
              $('#search-box').focusin();
        }
        else {
            $('#search-box').removeClass('active');
            $('#search-box').val("");
        }
    });  
});

感谢您的提前协助!

从 .nav-holder 中移除 overflow:hidden。您需要处理导航栏的布局以提高响应能力。

$(document).ready(function() {
  $('html').on('click', function(e) {
    if (e.target.id == 'search-icon') {
      $('#search-box').toggleClass('active');
      $('#search-box').focus();
    } else if (e.target.id == 'search-box') {
      $('#search-box').focusin();
    } else {
      $('#search-box').removeClass('active');
      $('#search-box').val("");
    }
  });
});
