jquery find() method syntax
Function: The find() method obtains the descendants of each element in the current element collection and filters them by selector, jQuery object or element.
Syntax: .find(selector)
Parameters:
| Parameter | Description |
| selector | String value, containing the selector expression for matching the current set of elements. |
Description: If given a jQuery object that represents a collection of DOM elements, the .find() method allows us to search for these elements in the DOM tree. descendants and constructs a new jQuery object with the matching elements. The .find() method is similar to the .children() method, except that it only traverses a single level down the DOM tree. The first obvious feature of the .find() method is that it accepts a selector expression of the same type as the expression we passed to the $() function. Elements will be filtered by testing whether they match the expression.
