Display HTML code within a data attribute

I have a function that modifies an element from OpenLayers.

In the official documentation, it mentions that the property label accepts either HTML or a string.

    methods: {
      onUpdatePosition (coordinate) {
        this.deviceCoordinate = coordinate;
        this.$refs.map.$map.getControls().extend([
          new ZoomToExtent({
            label: `<svg style="width:24px;height:24px" viewBox="0 0 24 24">
          <path fill="currentColor" d="M12,8A4,4 0 0,1 16,12A4,4 0 0,1 12,16A4,4 0 0,1 8,12A4,4 0 0,1 12,8M3.05,13H1V11H3.05C3.5,6.83 6.83,3.5 11,3.05V1H13V3.05C17.17,3.5 20.5,6.83 20.95,11H23V13H20.95C20.5,17.17 17.17,20.5 13,20.95V23H11V20.95C6.83,20.5 3.5,17.17 3.05,13M12,5A7,7 0 0,0 5,12A7,7 0 0,0 12,19A7,7 0 0,0 19,12A7,7 0 0,0 12,5Z" />
        </svg>`,
          })
        ])
      },
    }

The output is currently plain text, but I want to display actual HTML. How can I achieve that?

Answer №1

Make sure the label is an HTMLElement rather than a string with HTML content.

Here's a suggestion:

var myLabelHTML = document.createElement('span');
myLabelHTML.innerHTML = '<svg style="width:24px;height:24px" viewBox="0 0 24 24">
          <path fill="currentColor" d="M12,8A4,4 0 0,1 16,12A4,4 0 0,1 12,16A4,4 0 0,1 8,12A4,4 0 0,1 12,8M3.05,13H1V11H3.05C3.5,6.83 6.83,3.5 11,3.05V1H13V3.05C17.17,3.5 20.5,6.83 20.95,11H23V13H20.95C20.5,17.17 17.17,20.5 13,20.95V23H11V20.95C6.83,20.5 3.5,17.17 3.05,13M12,5A7,7 0 0,0 5,12A7,7 0 0,0 12,19A7,7 0 0,0 19,12A7,7 0 0,0 12,5Z" />
        </svg>';

//...

new ZoomToExtent({
      label:myLabelHTML;
    });
