# 有沒有方法可以變更預覽哪個 LaTeX 檔案？我的專案包含多個文件

目前，一個專案只能有一個主要檔案——也就是你瀏覽文件時會載入的那個檔案。

編譯另一個檔案的一個簡單方法是加入：

```latex
\input{other-file.tex}
```

作為主要檔案的第一行——甚至要放在文件類別之前。這樣我們就會改為編譯那個檔案，而 LaTeX 會忽略「主要」檔案其餘的部分。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-tw/zhi-shi-ku/098-is-there-a-way-to-change-which-latex-file-is-previewed-my-project-involves-several-documents.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
