未在光标所在的位置输入字符 [英] The characters are not getting typed where the cursor is

问题描述

在我的 Ace 编辑器中，就在滚动条出现之后，字符被输入，但不是光标所在的位置.见下图.出了什么问题?代码在我的开发环境中似乎运行正常.

In my Ace editor, just after the scroll bars appear, the character are getting typed but not where the cursor is. See the picture below. What has gone wrong? The code seem to work OK in my dev environment.

我注意到我的 dev 环境的字体比我的 prod 环境的字体大.

I notice that the font for my dev environment is bigger than the font of my prod environment.

我不明白为什么会有差异，以及这是否是问题的原因.

I don't understand that why there is a difference and if this is the cause of the issue.

将fonts显式设置为courier new后，编辑器选项为

After setting the fonts explicitly to courier new, the editor options are

更新

似乎编辑器中的每一行都有一个 ace_gutter-cell 类.此类与dev 和prod 环境不同.prod 中缺少 position:absolute.请参阅下面的图片.我是否选择了不同的 ace 版本?

Update

It seems each line in the editor gets a class ace_gutter-cell. This class is not the same the dev and prod environment. position:absolute is missing in prod. See the images below. Am I picking differing builds of ace?

推荐答案

当您使用非等宽字体时会发生这种情况；你必须在 Ace 中使用等宽字体.

This happens when you use a font that isn't monospaced; you have to use monospaced fonts with Ace.
