Question

I have this script which is used to append:

function append_place(type) {
      var shop_type = type;
      $("#shop_type").append(shop_type);
    }

Then in my view.html.erb:

<div id="shop_type"></div>

where and type is the data in my Rails database column.

When type has the value cafe and the output of the HTML is:

<div id="shop_type">Cafe</div>

When type has no value, the output of the HTML is:

<div id="shop_type"></div>

I want Javascript to insert Not available when type has no value:

<div id="shop_type">Not available</div>

How do I do that? I can’t use the normal if-else for Rails because the value is delivered via JSON.

Thanks.

Try something like this:

var shop_type = !type && type !== 0 ? 'Not available' : type;
