html - 下拉框和组合框有什么区别吗？

Question

下拉框和组合框[HTML]有什么区别吗？

其实重点是，每次我说:“组合框有问题”，我的学长说:“那不是下拉列表的组合框", :)

Answer 1

从技术上讲，HTML 中没有组合框，因为 <SELECT>无法输入。参见 the Wikipedia article on Combo Box (强调我的):

A combo box is a commonly-used graphical user interface widget. It is a combination of a drop-down list or list box and a single-line textbox, allowing the user to either type a value directly into the control or choose from the list of existing options.

虽然drop-down list的定义|与 HTML <SELECT> 完全匹配元素做:

When activated, it displays (drops down) a list of values, from which the user may select one.

所以你的前辈是对的。
