Concatenate strings in <Text>

How-to Discussions

It is possible to concatenate strings and variables in a Value?

I want something like this:

<Text Value="Something: {varFromJS}" />

Thanks!

Currently that’s not possible at the moment, but you can use Observable's map function to do this if your text is already in an Observable (https://www.fusetools.com/learn/fusejs#ref-map), for example:

    var varFromJS = new Observable("awesome");
    var prettified = varFromJS.map(function(x) {
        return "Something: " + x;
    });

Which would show Something: awesome :slight_smile:

Thanks Jake! But if varFromJS changes, prettified should be an Observable also if I use it in the UX? Or not?

That’s correct, but calling map on an Observable returns a new Observable, so prettified is already an Observable. Just bind to that instead of the original one, and you’re all set :slight_smile:
