Javascript 计时器偶尔运行

问题描述

我正在开发一个消息系统并通过这里的讨论:webBrowser.Document.Write() Irregular性能 我决定在我的程序中用 Javascript 重写一些核心登录.

I am developing a messaging system and through discussion here: webBrowser.Document.Write() Irregular Performance I decided to rewite some of the core login in my program in Javascript.

此处看到的演示:http://nathantornquist.com/code/misc/index6.当您添加来自 John 的消息时，html 可以完美运行.一旦您添加了来自 Jack 的消息，计时器就会变得一团糟，John 消息上的日期颜色停止更改.

The demo seen here: http://nathantornquist.com/code/misc/index6.html runs perfectly when you are adding messages from John.As soon as you add a message from Jack, the timer gets messed up and the color of the date on John's messages stop changing.

谁能看到一个明确的原因?

Can anyone see a clear reason why?

推荐答案

您是否检查了 Firefox 或 Chrome 中的控制台?我检查了它并在单击添加来自杰克的消息"时出错

Did you check the console in Firefox or Chrome? I checked it out and got an error when clicking "Add a message from Jack"

Uncaught ReferenceError: black is not defined
switchColorindex6.html:74
(anonymous function)

黑色是应该定义的变量吗?

Is black a variable that should be defined?
