This article is about not calling methods in created and watch when developing vue. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
Do not call methods in "created" and "watch"
A common mistake made by Vue developers is that they call methods unnecessarily in created and watch. The idea behind this is that we want to run watch as soon as the component is initialized.
/ / Bad practices created: () {this.handleChange ()}, methods: {handleChange () {/ / stuff happens}}, watch () {property () {this.handleChange ()}}
However, Vue provides a built-in solution for this, which is a Vue watch attribute that we often forget.
All we have to do is reorganize the watch slightly and declare two properties:
1.handler (newVal, oldVal)-this is our watch method itself. 2. Immediate: true- means that if it is declared in wacth, the handler method will be executed immediately. If it is false, the effect will be the same as before, and it will not be executed when binding.
/ / good practice methods: {handleChange () {/ / stuff happens}}, watch () {property {immediate: true handler () {this.handleChange ()} Thank you for reading!
