How can I set value of a data variable on if condition (if normal is selected then x = 3.3 else x = 4.5) how to do this in vue
watch
You can use a computed property x:
x
// In your component computed: { x: function () { return this.isNormalSelected ? 3.3 : 4.5 } }
Where this.isNormalSelected can be replaced with a condition that determines if "normal is selected".
this.isNormalSelected
