Ractive.js带有破折号的变量

Question

Back end (WordPress) generates JSON output:

sizes: {
thumbnail: "150x150.jpg",
thumbnail-width: 150,
thumbnail-height: 150,
}

In JS I can use variable with a dash that way: sizes['thumbnail-height'] . Unfortunately, in Ractive.js template {{sizes['thumbnail-height']}} does not work. How I can deal with this issue?

Answer 1

You can write the objects keys as string then you can use the - sign. That said is a good practice to avoid it and use camelCase style. If you realize for css attributes are always translated into camel case.

sizes: {
    'thumbnail': "150x150.jpg",
    'thumbnail-width': 150,
    'thumbnail-height': 150,
}
// Best
    sizes: {
        thumbnail: "150x150.jpg",
        thumbnailWidth: 150,
        thumbnailHeight: 150,
    }

The first case still works fine with Ractive (see http://jsfiddle.net/6hd3xt6t/ ) using the quoted property names like {{sizes['thumbnail-height']}}
