Using jQuery in Java - unknown error: $ is not defined

Question

I try to use the following script code in my Java/Selenium function:

return ((JavascriptExecutor)driver).executeScript("return $(':animated').length").toString().equals("0");

But when I execute the code the following error comes up:

unknown error: $ is not defined

How can I solve this?

The `$` variable which normally contains jQuery is undefined. Have you included the jQuery library within the scope the JS code is being executed? — Rory McCrossan, Nov 02 '16 at 10:31
I'm not familiar with selenium, so can't really guide you on that — Rory McCrossan, Nov 02 '16 at 10:34

The page you are running that command on does not have jQuery loaded. You either need to convert that command to JS (recommended) or load the jQuery library in the page. — JeffC, Nov 02 '16 at 13:41
`document.querySelectorAll(":animated").length`. also why are you doing that? with selenium, you can just do `driver.findElements(By.cssSelector(":animated")).length()` — ddavison, Nov 02 '16 at 16:52
Is this working with the jquery selector :animated? Your code gives me an InvalidSelectorException. — gartenkralle, Nov 02 '16 at 17:30
the selector @sircapsalot used is the one you provided in the question, so really if the selector is the issue then you need to provide some page source code! — Moe Ghafari, Sep 21 '17 at 18:11

Use document.querySelector inplace of $.

Your code would become

return ((JavascriptExecutor)driver).executeScript("return document.querySelector(':animated').length").toString().equals("0");
