描述

What version of Go are you using (`go version`)?

Does this issue reproduce with the latest release?

Yes.

What did you do?

https://go.dev/play/p/i3N0a5PATuI

What did you expect to see?

<b><no value></b>

This would align with the documented behavior of Template.Option.

"missingkey=default" or "missingkey=invalid" The default behavior: Do nothing and continue execution. If printed, the result of the index operation is the string "".

This is what text/template outputs.

What did you see instead?

<b></b>

贡献者指南

研究方向: 检查 html/template 包的源代码，特别是模板执行时缺失键的处理方式。与 text/template 的行为进行比较。查看 template.go 和 exec.go 等文件，找到默认 missingkey 行为的实现位置。Template.Option 的文档说明默认行为应输出 '<no value>'，但目前没有输出任何内容。查看链接的 issue，了解维护者的任何额外见解。
