This article delves into the core solution for handling DOM event bubbling issues in the Vue.js framework. When child elements (e.g., buttons) are nested within parent elements (e.g., divs), clicking the child triggers the parent's click event, which is often undesirable. By analyzing Vue.js's event modifier mechanism, particularly the use of the .stop modifier, the article explains in detail how to prevent events from propagating upward from child to parent elements. With concrete code examples, it demonstrates implementation methods in Vue 2 and Vue 3, compares the .stop and .self modifiers in different scenarios, and provides clear, practical technical guidance for developers.
