Using Angular Formly, I am using 'hideExpression' to hide a field based on another field's model value. This works as expected. However, I need to reset the hidden fields model value when it becomes hidden. How can this be accomplished in Angular-Formly? Is there some type of event I can hook?
you can use hideExpression callback and set model value before return true or false
{
key: 'model_key',
type: 'input',
templateOptions: {
label: 'Your label'
},
hideExpression: function ($viewValue, $modelValue, scope) {
var hide = true; // replace true with your condition
if (hide) {
vm.model.model_key = '';
}
return hide;
}
}
