[英]Html — display elements when button is clicked
我有以下html页面。 我的要求是:
1>按下顶部蔬菜按钮时,将显示6种蔬菜。
2>当按下顶部动物按钮时,将显示20只动物。
3>按下topautomobile按钮时,将显示26辆汽车。
我正在发布基本布局。 我在想的是在div“中心”中添加26个元素(因为div id =“ center”中的最大元素数可以不超过26个)。 并隐藏divs并根据按下的按钮更改图像和说明。
这是正确的方法。 请提出如何实现这一目标?

我建议添加一个类.vegatable,.car和.animal来分隔包含您的图像的div,并简单地在thme上执行show()/ hide()。 这将需要jQuery,但会使事情变得非常简单。
$('.animal').show(); // this will show all divs that have animal class set
$('.vegetable').hide(); // this will hide all divs that have vegetable class set
$('.car').hide(); // this will hide all divs that have car class set
这是jsfiddle示例: http : //jsfiddle.net/TbBgA/2/
