How To Use jQuery In Magento?

By default, Magento uses the Prototype javascript library. You can also integrate the javascript library "jQuery" in your Magento store. There is some problem to integrating jQuery in Magento, you might get some javascript conflict errors as your Magento store is using two javascript libraries one is prototype.js and another one id jQuery.js at a same time. This is caused because prototype as well as jQuery uses "$" as a function or variable name. Don't worry about it because jQuery has a solution for such kind of conflict case.

Many JavaScript libraries use $ as a function or variable name, just as jQuery does. In jQuery case, $ is just an alias for jQuery, so all functionality is available without using $. If we need to use another JavaScript library alongside jQuery, we can return control of $ back to the other library with a call to $.noConflict(). Old references of $ are saved during jQuery initialization; noConflict() simply restores them.
