I want to select an item from an unordered list

I need to add a class to the list item that matches document.title.

My understanding is that I need to do something along the lines of

$('.mylist li:contains(thetitle)').addClass('blah')

but c开发者_开发百科ontains seems to take a string rather than a variable. I am sure this is obvious, but I have wasted a stupid amount of time on it already. Thanks in advance.

Just add the document.title to using standard string concatenation:

$('.mylist li:contains(' + document.title + ')').addClass('blah');

You mean like this $('.mylist li:contains(' + document.title + ')').addClass('blah')?

You'll have to quote the variable, since contains requires a string as a parameter. Additionally, if the document.title can contain quotes itself, you'll have to escape them.

var escaped = document.title.replace('\'', '\\\'');
$('.mylist li:contains(\'' + escaped + '\')').addClass('blah');
