Why cant Dollar symbol be used as an alternative fo jQuery in Wordpress?

Question

Why can\'t we use \"$\" instead if jQuery in wordpress? Usually \"$\" is the alternative of jQuery right? But in Wordpress it shows \"$\" is not a function.

Answer 1

jQuery(...) should be used instead of $(...)

Edit ---- sorry, i misread your question. It depends on the jquery implementation of your wordpress version. I have seen wordpress sites that allowed the usage of $ before, but i don't really know what it depends on.

Answer 2

Have a look at tip 5 in this web page: 5 Tips for using jquery with wordpress:

It is important to know that the version of jQuery that comes with WordPress automatically calls the jQuery.noConflict(); function, which gives control of the $ variable back to whichever library first implemented it. If you are loading a different copy of jQuery, you'll need to manually call jQuery.noConflict();, if necessary, from one of your JavaScript files.

I hope that helps.

Answer 3

The tricky thing is this particular copy of jQuery is in compatibility mode by default. That means that the typical ‘$’ shortcut for jQuery doesn’t work, so it doesn’t conflict with any other JavaScript libraries that use the dollar sign also, like MooTools or Prototype.
