To check for this, try disabling any other libraries you are using and see if the error goes away. If it does, then you will need to find a way to make the two libraries compatible.<\/p>\n<p>Finally, if you are sure that you are using the latest version of jQuery and there are no conflicts with other libraries, then the problem may be caused by a typo in your code. Check your code for any typos or incorrect syntax and make sure that you are using the correct syntax for the <code>hasClass()<\/code> method.<\/p>\n<p>In conclusion, if you are getting an error that <code>hasClass()<\/code> is not a function in jQuery, it is likely because you are using an outdated version of jQuery, there is a conflict with another library, or there is a typo in your code.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction [ad_1] The jQuery hasClass() method is a powerful tool for manipulating the class attribute of HTML elements.
