If I have two data properties:
data() {
return {
a: false,
b: false,
}
}
Is there a way to trigger a specific task when both a and b are set to true simultaneously using Vue's watch method?

Monitor a computed value.
computed:{
combined(){
return this.a && this.b
}
}
watch:{
combined(value){
if (value)
//perform an action
}
}
There is a more concise way to achieve the same using $watch.
vm.$watch( function () { return this.a + this.b }, function (newVal, oldVal) { // perform an action } )
Essentially, the solution is similar to what @Bert recommended. However, you can achieve the same result by following these steps:
data() {
return {
combined: {
a: false,
b: false,
}
}
},
Then:
watch: {
combined:{
deep:true,
handler
}
}
