I'm on Vue 3. I have an onclick method which is supposed to modify the value of my props which is a boolean, I have tried several ways, I manage to enter the computed method, but the value of my props does not change
I register my data
data() {
return {
showConsommationWindow: false
}
}
then I tried 3 ways to change the value but none of them worked. The first :
<submit-button v-on:click="showConsommationWindow = true" />
the 2nd : (alert is executed but the data value don't change)
<submit-button v-on:click="showConsommation(true)"/>
methods: {
showConsommation(boolValue){
alert('false')
this.showConsommationWindow = boolValue;
}
}
The last :
<submit-button v-on:click="showConsommation"/>
methods: {
showConsommation(){
if (!this.showConsommationWindow) {
alert('false')
this.showConsommationWindow = true;
return
}
this.showConsommationWindow = false;
}
},
I really don't understand why my data can't mutate, thanks for your help.
If value comes from a props, it means the parent distributes a boolean to the component. So if you want to change the boolean value, you should probably do:
// in parent
<Component :booleanValue="myBoolean" @changeBooleanValueEvent="changeMyBoolean" />
...
data() {
return {
myBoolean: true
}
}
methods: {
changeMyBoolean(value) {
this.myBoolean = value
}
}
// in component
props: {
booleanValue: {
...
}
}
methods: {
showConsommation() {
this.$emit('changeBooleanValueEvent', false)
}
}
