Access previous values
rockingskier opened this issue · comments
Would it be possible to access the previous value of the changed input? This would allow for swapping values around.
For example:
{
field: 'opt1',
updates: {
opt2: (opt1Value, allValues, prevOpt1Value) => prevOpt1Value
}
}
Ehy guys do you still think this is useful?
I created a pr for that (#24), I personally have a particular use case and this is useful form me.
Basically I want to initialize a form with value but since I have some values that on change needs to clear some other I end up having a clean form instead of an initialized one.
Adding previous values I can check if the previous value is undefined and prevent the update to happen, or well return the current value instead.
Let me know
