How can I create a comma-separated list in SAPUI5?

Question

I try to make a comma-separated list of authors in a headerObject.

I have a binding and expand a list of authors (ManyToMany):

<ObjectHeader responsive="true" fullScreenOptimized="true" title="{database>Title}" intro="{i18n>details_by} {database>AuthorDetails}">

This code gives me the following result:

With {database>AuthorDetails/Name} it shows me nothing. How can I expand the authors?

Answer 1

i think we can simplify have function in the controller

commaSeparator: function(oData) {
    if (oData === null) {
        return "";
    }

    var oModel = this.getView().getModel("database");
    return oData.reduce(function(result, authorKey) {
      var obj = oModel.getProperty("/" + authorKey);
      return result === "" ? obj.Name : result + ", " + obj.Name;
    }, "");
},
