I don't want to ask this stupid question, but I have searched all over the stackoverflow and google, it seems jquery has no one ever talk about 'and' function in jquery. I use && in php, but what should I use for jquery?

3You could simply just have tried if `&&` worked in jQuery, which it does. – Cyclonecode Feb 15 '15 at 22:43

3`&&` is actually JavaScript, not jQuery. – Alexander O'Mara Feb 15 '15 at 22:43

The logical and operator in php is && and and, they are not exactly the same though.
See PHP : Difference between '&&' and 'AND'
If you want to use the logical and operator in JavaScript (using jQuery) it is &&
if ($('#all').is(':visible') && $('#none').is(':visible')){
// We have a problem
}

jQuery isn't a language, but a plugin for javascript. You would use && in javascript as "and" operator just as you would do in php.

Do you have an example of some other description of the `&&` statement? – Sumner Evans Feb 15 '15 at 22:49

If I understand your question correctly you want to use the && logical operator in jQuery?
jQuery is a JavaScript library so you can use &&. Here is the documentation from JavaScript.
If you are trying to select multiple elements I suggest you use the following:
$("element1, element2").click(function() {...

MDN has an article outlining Logical Operators in JavaScript. It states:
Operator: Logical AND (
&&)
Usage:
expr1&&expr2
Description: Returns
expr1if it can be converted to false; otherwise, returnsexpr2. Thus, when used with Boolean values,&&returnstrueif both operands aretrue; otherwise, returnsfalse.
