# JavaScript 字符串中的 XSS，带编码的尖括号、编码的双引号和已转义的单引号
JavaScript 字符串中的 XSS，带编码的尖括号、编码的双引号和已转义的单引号笔记，适用于 PortSwigger Web Security Academy 实验室，包括利用流程、载荷测试，
### 带有尖括号和双引号 HTML 编码、单引号转义的 JavaScript 字符串中的反射型 XSS
此实验室包含一个反射型 XSS 漏洞：搜索值会被插入到一个 JavaScript 字符串中。 `<`/`>` 并且双引号会进行 HTML 编码，单引号会被转义。目标：跳出 JavaScript 字符串并调用 `alert()`.
从观察到的脚本中提取
```javascript
var searchTerms = '</h1>/'';
document.write('');
```
观察到的限制条件
* 单引号被转义（`/'`).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/zh/web/xss/xss-in-a-javascript-string-with-encoded-angle-brackets-encoded-double-quotes-and-escaped-apostrophe.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
