Special uses ​

Security level UI ​

We can use some extra Javascript and CSS to achieve a more visual validation interface for our password inputs. In this case we bind the input model and we use the help-text slot to present a discretized progress made with <div> tags that are activated with a data-active attributed that is set depending of the model length. We make the input invalid if the model length is 0.

So with some extra JavaScript added to this HTML:

And some SCSS styling, we achieve the functionality:

scss
#security-example {
  &:has(div[data-active] + div[data-active])::part(input) {
    border-color: var(--zc-lemon-aa);
  }

  &:has(div[data-active] + div[data-active] + div[data-active])::part(input) {
    border-color: var(--zc-moss-100);
  }

  output[slot="help-text"] {
    display: grid;
    gap: var(--zs-25);
    grid-template-columns: repeat(3, 1fr);
    padding-top: var(--zs-25);
    width: 100%;

    > div {
      background-color: var(--zg-8);
      height: var(--zs-50);
    }
    > div[data-active] {
      background-color: var(--zc-peach-aa);

      &:has(+ div[data-active]),
      &:first-child + div[data-active] {
        background-color: var(--zc-lemon-aa);
      }
      &:has(+ div[data-active] + div[data-active]),
      & + div[data-active]:has(+ div[data-active]),
      &:last-child {
        background-color: var(--zc-moss-100);
      }
    }
  }
}

Methods ​

reset() ​

We can all the reset() method of the WebComponent in order to reset the value. This will clean the internal states and emit the nullable value with the change event, plus a restarted event:

In this example, the button triggers the method:

Value:  undefined
