如何搜索属性值为“ \\”的元素？

Question

I have an element inside my html with attribute "test" having value "\\". eg

<e1>
 <e2 test="\"></e2>
</e1>

Now when I do a find to get the element as follows: elem.find('[value="\\"]') I get following error:

error: Syntax error, unrecognized expression: [value="\"]

Any ideas on how to fix this ?

Answer 1

Corrected by @Karl-André Gagnon: it should be \\\\\\\\ and test= , not value= :

$('e1').find('[test="\\\\"]');

Fiddle .

Answer 2

In the documentation it says you need to add double slashes to escape a special character. But since \\ by itself is an escape character, it needs to be doubled up. As a result, you need to have 4 slashes to match a single slash.

$('[test="\\\\"]')

And I mentioned in my comment, you have no attribute value, it is test. And the jQuery documentation has a list of all the special characters in selectors that need to be escaped.
