The difference between created and mounted in Vue
In the life cycle of the Vue component, created
and mounted
are two crucial hook functions. They are used to perform specific tasks at different stages of a component, but they have some key differences in terms of execution time and availability.
Created
- Instantiate or call
this.$mount()# in
new Vue()## method is called immediately.
Can only access the data of the Vue instance ( - this.data
).
At this time, the DOM has not been rendered, so you cannot interact with DOM elements.
Mounted
- Called immediately after the DOM is mounted.
- In addition to Vue instance data, you can also access DOM elements (
- this.$el
).
You can interact with DOM elements, such as manipulating styles, adding event listeners, or performing DOM queries.
