Question

目标：
单击带有图标阅读玻璃a的按钮时，文本字段应从右向左进入。

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，并且应显示按钮周围的颜色框，例如黄色。

当您在文本字段外使用光标时，突然按下鼠标左键，文本字段和按钮周围的黄色颜色将消失。

问题：
我现在不知道如何创建它。

的信息：
*我使用bootstrap和jQuery *今天，我没有可用的源代码。

Answer 1

您需要的是按钮上的两个操作：

显示输入字段
触发表格

以下代码就是这样做的。页面加载时输入的宽度为零。 jQuery函数绑定按钮上的click事件。

单击它时，将查看输入字段是否具有宽度。如果没有，它将阻止默认操作（提交表单），而是将输入设置为200px的宽度。之后，它专注于该领域。

第二次单击按钮时，输入的宽度不会为零，因此按钮动作正常并将提交表单。

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');
        }
    });
