Question

我正在使用基于CSS的动画搜索表单：

DEMO：https://codepen.io/CBeghin/pen/HeuiF

要打开搜索栏，我必须点击放大镜图标。如果我再次点击放大镜图标，则该栏会再次消失。目前我必须按“Enter”键才能搜索我的关键字。

在放大镜图标上第二次点击时，我想使用输入操作来搜索我的关键字，而不是删除搜索栏。

我试图使用javascript，但我没有在正确的地方采取行动：

input()

有人有想法，如何实现这个目标？

您可以通过javascript处理焦点样式，并在用户第一次点击文本输入前移动放大镜来完成此操作

$("input[type='text']").focus(function() {
    if (!$(this).hasClass("focus")) {
  	$(this).addClass("focus");
    }
  $("input[type='submit']").attr('style', 'z-index: 4');
});
