Which quotation marks to use and when?

Question

for example here in documentation http://api.jquery.com/attribute-contains-selector/ it says

$('input[name*="man"]')

I would write instead

$("input[name*='man']")

is there any reason to use single or double quotation marks on inside or outside ?? is it just a matter of taste?

Answer 1

It's just a matter of taste, and sometimes convenience.

You are using quotation marks both in Javascript and in a jQuery selector, and in both cases you can use either apostrophes (') or quotation marks (") to delimit strings.

In some cases it's more convenient to use one type over the other, for exampe when you have Javascript code in an HTML attribute, as apostropes doesn't need to be escaped:

<div onclick="alert('Hello world!');">

compared to:

<div onclick='alert(&quot;Hello world!&quot;)'>
