javascript - 如何使用 jquery 或 css3 使搜索栏响应

Question

function searchToggle(obj, evt) {
  var container = $(obj).closest('.search-wrapper');
  if (!container.hasClass('active')) {
    container.addClass('active');
    evt.preventDefault();
  } else if (container.hasClass('active') && $(obj).closest('.input-holder').length == 0) {
    container.removeClass('active');
    // clear input
    container.find('.search-input').val('');
  }
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>

<div class="search-wrapper">
  <div class="input-holder">
    <input type="text" class="search-input" placeholder="Type to search" />
    <button class="search-icon" onclick="searchToggle(this, event);"><span></span>
    </button>
  </div>
  <span class="close" onclick="searchToggle(this, event);"></span>
</div>

经过大量研究，我终于设法做出更改并定位了我的搜索栏。但据我所知，它没有执行搜索功能。 例如，如果我在其中键入任何内容(例如“home”)并按下搜索图标，则不会发生任何事情。所以我想问问我是否错了，即搜索功能是否正常工作，其次我想让它像 Google 的搜索栏一样响应。我的意思是我希望它记住搜索并在我输入时缩短结果。

任何帮助将不胜感激。谢谢:)

我强烈建议您使用 Bootstrap .它只使用 CSS 并且是轻量级的。您可以在 Bootstrap Forms 找到它的详细记录和 W3S .如果您不想使用框架，您可以尝试自己构建一些东西。为此，您可以简单地再次查看 bootstrap(或其他 CSS 框架)并复制您想要使用的任何内容。

同样，您应该使用 CSS 框架进行响应式设计，它们有很大帮助，让您的生活更轻松。
