Vue Computed Parameters: How to Pass Arguments
In Vue, the computed property relies on its dependencies caching, only recalculating when the dependency changes. This is why computed properties typically do not accept parameters.
If you need to pass parameters to a computed property, you can dynamically calculate the property value using a function instead of passing the parameters directly in the computed property. For example:
data() {
return {
param: 10
}
},
computed: {
dynamicComputed() {
return this.param * 2;
}
}
In the given example, we simulate passing parameters by defining a ‘param’ attribute in the data. Then, we use ‘this.param’ in the computed property to dynamically calculate property values. When ‘this.param’ changes, the ‘dynamicComputed’ property will be recalculated.
