问题描述

有人知道下拉列表中有多少个选项？是无限的？有没有人知道下拉列表中有多少个选项？

解决方案

？是无限的？

我想象在理论上是无限的，显然不是在实际中作为计算机的RAM和具体的浏览器的限制发挥作用。 p>

性能下降前有多少？

再次，这取决于几个因素，至少具体的浏览器，计算机的内存和处理能力。

编辑从经验来看，我已经有了数千个选项的下拉列表。这不是理想的，因为谁想滚动所有这些？这就是为什么一些类型的自动完成是因为许多原因，特别是最终用户的体验而更为理想的。

Does anyone know how many options a drop down list can have? Is it unlimited? How many before performance degrades?

解决方案

Does anyone know how many options a drop down list can have? Is it unlimited?

I imagine it is unlimited in theory, obviously not in practice as a computer's RAM and the specific browser's limitations come into play.

How many before performance degrades?

Again, this would depend on a few factors, at the least the specific browser, the computer's memory and processing power.

EDIT: From experience, I have had drop down lists with thousands of options. It wasn't ideal though because who wants to scroll through all of those? This is why an auto-complete of some type is more desirable for numerous reasons, especially the end user's experience.
