eventcurrentTargetvalue

EventcurrentTargetvalue refers to the value property accessed through the currentTarget of an event in web development. It is a shorthand way of describing how to read the content of form controls from an event handler. The concept hinges on two event properties: currentTarget and target, and the value property that form controls expose.

event.currentTarget is the element to which the event listener is attached. event.target is the element that actually initiated the event, which can be a descendant of currentTarget if the event bubbles. The value property exists on form controls such as input, textarea, and select, and represents their current content.

When using event.currentTarget.value, you are reading the value of the element that has the listener, provided that element supports a value property. If you attach a handler to a parent element via event delegation, currentTarget may refer to that parent, which might not have a meaningful value. In delegated scenarios, use event.target.value to obtain the actual origin input’s value.

Examples in plain JavaScript: element.addEventListener('input', function(e) { console.log(e.currentTarget.value); }); In a delegated handler on a container: container.addEventListener('input', function(e) { console.log(e.target.value); });

Notes: In React and other libraries, event objects may be pooled or synthetic; reading values should generally be done synchronously within the handler, or the value captured beforehand if needed later.
