Empty Variable Gives True Value To Disabled Attribute On Input April 16, 2024 Post a Comment I dont know if this is a problem or normal behavior. If we have a form like this: field1Solution 1: UPDATEI found the answer to this in the angular source code (<3 open source!). The ngModel controller explicitly checks for '' when the disabled input is changed. If the input strictly equals '', the element will be disabled. So this behavior is by design.Here is how to source code looks (link to GitHub, see line 142 and 217) const isDisabled = disabledValue === '' || (disabledValue && disabledValue !== 'false'); CopyThis means that you cannot use an empty string as falsy to set an input that is using ngModel to disable it.
