For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree. Given a jQuery object that represents a set of DOM elements, the .closest() method searches through these elements and their ancestors in the DOM tree and constructs a new jQuery object from the matching elements. The .parents() and .closest() methods are similar in that they both traverse

Selects all elements of type checkbox. $( ":checkbox" ) is equivalent to $( "[type=checkbox]" ). As with other pseudo-class selectors (those that begin with a ":") it is recommended to precede it with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare $(':checkbox') is equivalent to $( "*:checkbox" ), so $( "input:checkbox" ) should be used instead. Because :checkbox is a jQuery extension

.click()

Bind an event handler to the "click" JavaScript event, or trigger that event on an element. This method is a shortcut for .on( "click", handler ) in the first two variations, and .trigger( "click" ) in the third. The click event is sent to an element when the mouse pointer is over the element, and the mouse button is pressed and released. Any HTML element can receive this event. For example, consider the HTML: <div id="target"> Click here <

.change()

Bind an event handler to the "change" JavaScript event, or trigger that event on an element. This method is a shortcut for .on( "change", handler ) in the first two variations, and .trigger( "change" ) in the third. The change event is sent to an element when its value changes. This event is limited to <input> elements, <textarea> boxes and <select> elements. For select boxes, checkboxes, and radio buttons, the event is fired immedia
