change() Method

Events in jQuery are the actions that the user performs on the web page. It can be anything – related to mouse clicks, keyboard presses, etc. Using jQuery, we can control these events in the order we want and can also attach some custom functions to it if needed. That means, we can use predefined event methods for the actions and also define a function that gets fired when the event method is triggered. Overall, this makes the website more dynamic on the user's end. Let's learn about the change() method here.

The change() method is a built-in jQuery method. It helps to detect the change in the text of the input element or the text area. In other words, we can say that the change event gets triggered whenever the input text is changed by the user. Some kind of function can be attached to perform other tasks. This method generally works for the form fields, input, '<textarea>', etc.
