我正在尝试编写一个代码,只要单击一个按钮,就会为用户提供更多选项。 例如说我有一个带有两个按钮的页面,一个“搜索书籍”,另一个“搜索事件”。如果用户点击“搜索图书”按钮,则在搜索按钮正下方的同一页面上,我希望显示不同的选项。我尝试使用css visibility:hidden函数并将其切换回可见性:使用javascript函数可见。它确实有效,但屏幕上的巨大空间被保留用于隐藏元素。主窗口按钮彼此相距很远。一边是“搜索书籍”按钮,远离它的是“搜索事件”按钮。
以下是代码的一部分

答案 0 :(得分:2)
改为使用
display : none
除了元素占用的空白空间外,它的作用相同。
看着这些标签,你就有了jQuery。您可以改为使用.hide()
和.show()
。
