如何为快捷方式创建自定义搜索功能

Question

目标：
当您单击带有图标阅读玻璃 a 的按钮时，应该从右到左输入一个文本字段。

按下按钮后，光标应位于文本字段中并准备好检索输入数据，并且按钮周围会出现一个颜色框，例如黄色。

当您使用文本字段外的光标并突然按下鼠标左键时，文本字段和按钮周围的黄色应该会消失。

问题：
我现在不知道如何创建它。

信息：
*我正在使用引导程序和 jQuery。
*今天，我没有可用的源代码。

Answer 1

您需要在按钮上执行两个操作：

1. 显示输入字段
2. 触发表单

下面的代码就是这样做的。页面加载时输入的宽度为零。 jQuery 函数在按钮上绑定了一个点击事件。

当它被点击时，它会查看输入字段是否有宽度。如果没有，它将阻止默认操作（提交表单），而是将输入动画设置为 200px 的宽度。之后，它专注于该领域。

第二次点击按钮时，输入的宽度不会为零，所以按钮会正常工作并提交表单。

希望它适合你。

$(function() {
    $('#search-form button').on('click', function(e) {
        var btn = $(this);
        var inp = $(this).parent().find("input");
        
        if( inp.width() == 0 ) {
            e.preventDefault();
            inp.animate({width: "200px"}, 500).focus();        
            btn.addClass('active-btn');
        }
    });
});
