for example here in documentation / 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?

for example here in documentation http://api.jquery./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?

• 1 @ShaiMishali: Not a duplicate, as this also involves the syntax for jQuery selectors. – Guffa Commented Jan 15, 2012 at 9:39
• @Guffa I don't really agree. jQuery is just a Javascript library and the "quotes" thing is the same for both. – Shai Mishali Commented Jan 15, 2012 at 14:52
• 2 @ShaiMishali: Yes, jQuery is not a separate language, but the selectors used by jQuery is. It's not Javascript that is used in the selectors, but a syntax based on CSS selectors. The fact that Javascript syntax and selector syntax uses the same quotation marks has nothing to do with the fact that jQuery is a Javascript library. – Guffa Commented Jan 15, 2012 at 14:59

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!');">

pared to:

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

Yes, it's a matter of taste. I generally use double quotes when the string literal contains single quotes, and vice-versa, to avoid having to escape them.
