3🚫 This rule is _disabled_ in the ☑️ `recommended` config.

7Enforces `<a>` values are not exact matches for the phrases "click here", "here", "link", "a link", or "learn more". Screen readers announce tags as links/interactive, but rely on values for context. Ambiguous anchor descriptions do not provide sufficient context for users.
8
9## Rule options
10
11This rule takes one optional object argument with the parameter `words`.
12
13```json
14{
15 "rules": {
16 "jsx-a11y/anchor-ambiguous-text": [2, {
17 "words": ["click this"],
18 }],
19 }
20}
21```
22
23The `words` option allows users to modify the strings that can be checked for in the anchor text. Useful for specifying other words in other languages. The default value is set by `DEFAULT_AMBIGUOUS_WORDS`:
24
25```js
26const DEFAULT_AMBIGUOUS_WORDS = ['click here', 'here', 'link', 'a link', 'learn more'];
27```
28
29The logic to calculate the inner text of an anchor is as follows:
30
31- if an element has the `aria-label` property, its value is used instead of the inner text
32- if an element has `aria-hidden="true`, it is skipped over
33- if an element is `<img />` or configured to be interpreted like one, its `alt` value is used as its inner text
34
35Note that this rule still disallows ambiguous `aria-label` or `alt` values.
36
37Note that this rule is case-insensitive, trims whitespace, and ignores certain punctuation (`[,.?¿!‽¡;:]`). It only looks for **exact matches**.

39### Succeed
40
41```jsx
42<a>read this tutorial</a> // passes since it is not one of the disallowed words
43<a>${here}</a> // this is valid since 'here' is a variable name
44<a aria-label="tutorial on using eslint-plugin-jsx-a11y">click here</a> // the aria-label supersedes the inner text
45```
46
47### Fail
48
49```jsx
50<a>here</a>
51<a>HERE</a>
52<a>link</a>
53<a>click here</a>
54<a>learn more</a>
55<a>learn more.</a>
56<a>learn more,</a>
57<a>learn more?</a>
58<a>learn more!</a>
59<a>learn more:</a>
60<a>learn more;</a>
61<a>a link</a>
62<a> a link </a>
63<a><span> click </span> here</a> // goes through element children
64<a>a<i></i> link</a>
65<a><i></i>a link</a>
66<a><span aria-hidden="true">more text</span>learn more</a> // skips over elements with aria-hidden=true
67<a aria-label="click here">something</a> // the aria-label here is inaccessible
68<a><img alt="click here"/></a> // the alt tag is still ambiguous
69<a alt="tutorial on using eslint-plugin-jsx-a11y">click here</a> // the alt tag is only parsed on img
70```
71
72## Accessibility guidelines
73
74Ensure anchor tags describe the content of the link, opposed to simply describing them as a link.
75
76Compare
77
78```jsx
79<p><a href="#">click here</a> to read a tutorial by Foo Bar</p>
80```
81
82which can be more concise and accessible with
83
84```jsx
85<p>read <a href="#">a tutorial by Foo Bar</a></p>
86```
