如何在jQuery内部函数中正确使用$

Question

I use the following ocde so I can use the $ short hand for jQuery:

jQuery(function($){ ... }

But I also have a few functions outside it that require jQuery. How can I still use the $ short hand within those functions? It seems like $ won't work within my functions.

Answer 1

You cannot use $ outside of that function if you have another script on the page that uses $ as their object. However, you can use noConflict to create an alias of $ or jQuery .

(function($) {
    // Use $ here
})(jQuery);


// Create an alias of jQuery
var $_ = jQuery.noConflict();

// Use $_ here

Answer 2

Remove the jQuery on the front and put after that:

(function($){
  ///
})(jQuery); // Use jQuery here
