问题 Inside a function I have an event handler. So far so good. But in that event handler I want to capture Enter pressed and replace that for a HTML.

问题 This question already has answers here : Why the onclick element will trigger twice for label element (5 answers) Closed 3 years ago . I have an click event on window . There is also a checkbox and a label for the checkbox. When you click on the label, the window's click event gets called twice, once for the checkbox, and once for the label.
