You should use forward slashes (`/`), not backslashes (`\\`) in URLs anyway. — AKX, Dec 05 '18 at 16:24
Backslash is an escape character. You'll need to escape the escape character. — evolutionxbox, Dec 05 '18 at 16:24

The '\' character is an escape character, it needs to be escaped to be printed like:

console.log('\\');

Will print '\'

Just escape the character with another \

document.getElementById('menu_links').innerHTML+="<li><a href='CRUD\\data.php'>Data</a><\li>";
console.log('CRUD\\data.php'); //print path

<span id="menu_links"></span>

Edit: always use forward slash for URLs like http://example.com/CRUD/data.php, that way you wont have this problem and the code will be compatible across browsers.

Good answer, but now the URL is using a backslash not a forward slash. – evolutionxbox Dec 05 '18 at 16:24
@evolutionbox is correct, Chrome automatically converts the backslash to a forward slash but that is not true for all browsers so it would be better to just correct it to a forward slash. – benvc Dec 05 '18 at 16:28
