Function umbBindToValidation

Description

A Lit directive, which binds the validation state of the element to the Validation Context.

The minimal binding can be established by just providing a host element: @example:

html`<input ${umbBindToValidation(this)}>`;
Copy

But can be extended with a dataPath, which is the path to the data holding the value. (if no server validation in this context, then this can be fictive and is then just used internal for remembering the validation state despite the element begin removed from the DOM.) @example:

html`<input ${umbBindToValidation(this, '$.headline')}>`;
Copy

Additional the value can be provided, which is then used to remove a server validation state, if the value is changed. @example:

html`<input ${umbBindToValidation(this, '$.headline', this.headlineValue)}>`;
Copy
