HTL Syntax Error

Actually, I am struggling to implement if condition logic in a component. When I execute the below syntax, it is not working.

<a href="#" class="${properties.modalBehavior == 'sideOverlay' ? 'side-overlay-link' : ''} ${properties.modalBehavior == 'sideOverlayTable' ? 'side-overlay-link' : ''} ${properties.modalBehavior == 'fullOverlay' ? 'overlay-link' : ''}"> ${properties.ctaText} </a>

 

I don't know where I was wrong. Kindly help!

Hi @ameen_dev ,

Try this

<a href="#" class="${properties.modalBehavior == 'sideOverlay' ? 'side-overlay-link' : '' || properties.modalBehavior == 'sideOverlayTable' ? 'side-overlay-link' : '' || properties.modalBehavior == 'fullOverlay' ? 'overlay-link' : ''}">
        ${properties.ctaText}
</a>

However, I would implement Sling Model - as it is recommended to segregate markup and business logic.

Sling Model

@Inject
private String modalBehavior;

public String getCSSClass() {
    if (modalBehavior.equalsIgnoreCase("sideOverlay")) {
        return "side-overlay-link";
    } else if (modalBehavior.equalsIgnoreCase("sideOverlayTable")) {
        return "side-overlay-link";
    } else if (modalBehavior.equalsIgnoreCase("fullOverlay")) {
        return "overlay-link";
    }
    return StringUtils.EMPTY;
}

HTL

<a href="#" class="${model.CSSClass}">
    ${properties.ctaText}
</a>

Hope that helps!

Regards,

Santosh

>${properties.ctaText}</a>

I tried this, looks fine for me

    I'm just an HTL beginner myself, but it looks like you've inserted ["}]'s where they don't belong. In your code snippet 

    'side-overlay-link' : "}

    can you explain what the "} is there for?

      public String getCSSClass() {
          if (modalBehavior.equalsIgnoreCase("sideOverlay")) {
              return "side-overlay-link";
          } else if (modalBehavior.equalsIgnoreCase("sideOverlayTable")) {
              return "side-overlay-link";
          } else if (modalBehavior.equalsIgnoreCase("fullOverlay")) {
              return "overlay-link";
          }
          return StringUtils.EMPTY;
      }

      HTL

      <a href="#" class="${model.CSSClass}">
    ${properties.ctaText}
</a>

      Hope that helps!

        I agree, a sling model should be used to handle logic, and HTL should be used for rendering the compiled data from the model.

          Hi @ameen_dev, 

          As @santoshsai said, I would also suggest to use a sling model to retrieve the value. I also recommend you to use "data-sly-attribute.class" while reading dynamic class values so as to – not to leave class empty when nothing is authored.

          <a href="#" data-sly-attribute.class="${model.CSSClass}">
    ${properties.ctaText}
</a>
