How to set the selected item in a radio button group in handlebars template?

Question

In a handlebars template, how do you set a radio button group to the right value using only the template? Can this be done directly in the template?

For an example,

Answer 1

My own solution is:

helper:

Handlebars.registerHelper ("setRadio", function (value, options) {
    var $el = $(options.fn(this));
    if ( value == $el.val() ) {
       return $el.attr("checked", "checked")[0].outerHTML;
    } else {
       return options.fn(this);
    }

Usage in template:

            {{#setRadio stars}}{{/setRadio}}
            

            {{#setRadio stars}}{{/setRadio}}
            

            {{#setRadio stars}}{{/setRadio}}
            

            {{#setRadio stars}}{{/setRadio}}
            

            {{#setRadio stars}}{{/setRadio}}
