我已经通过了一些建议问题，阅读激发，但我不知道究竟如何实现它们：添加延迟之前的keyup（）jQuery中
- (jquery/js) - get text from field on keyup, but with delay for further typing
- How to delay the .keyup() handler until the user stops typing?
- How to trigger an onkeyup event that's delayed until a user pauses their typing?
我有8个文本框，7个用于数字输入，8个是总数。 即7.5 + 7.5 + 7.5 + 7.5 + 7.5 + 0.0 + 0.0 = 37.5
我有jQuery的工作，以便它监视每个文本框的keyup（）并添加所有的值并计算总和。
我决定要格式化7个文本框中的用户输入，以便在输入“1”或“.1”（即“1.0”或“0.1”）时显示为＃。＃。
问题是我需要在格式化输入之前添加一个延迟，我不确定我是如何使用javascript和/或jquery进行操作的。

在一个完全不相关的说明。我会建议干掉你的代码。你做了7次完全相同的事情，在这个过程中，你做了7次每件事。 – bstakes
