【问题描述】：
我已经阅读了一些建议的问题，但我不确定如何实施它们：
- (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，第 8 个是总数。 即 7.5 + 7.5 + 7.5 + 7.5 + 7.5 + 0.0 + 0.0 = 37.5
我让 jQuery 工作，以便它监视每个文本框 keyup() 并添加所有值并计算总数。
我决定要格式化用户在 7 个文本框中输入的内容，这样如果他们输入“1”或“.1”，即“1.0”或“0.1”，它就会像 #.# 一样出现。
问题是我需要在输入格式化之前添加一个延迟，我不确定如何使用 javascript 和/或 jquery 来做到这一点。

理想情况下，我想触发这条线：
$('input[id*="txtMondayHours"]').val((new Number($('input[id*="txtMondayHours"]').val())).toFixed(2));
在指定时间后，例如100毫秒
更新的工作代码：
<script type="text/javascript">
var delay = (function () {
var timer = 0;
return function (callback, ms) {
clearTimeout(timer);
timer = setTimeout(callback, ms);
};
})();

在一个完全不相关的注释上。我会建议干燥你的代码。你做同样的事情 7 次，在这个过程中，你每次做另一件事 7 次。
