Concatenate in Meteor Template Tags

Question

I have a list of numbers in my Meteor Template which I am iterating to print the attributes of the object. I have an object named choices_object which will have number of choices depending upon the situation. objects fields will be choice_1 choice_2 choice_3 and so on. I have the same number of values in an array as object fields.

values=[1,2,3,4,5,6,7,8,9]

In my template I have to concatenate the name of objects fields with this number to complete the names of fields.

<template name="choices_template">
    {{#with choices_object}}
        {{#each values}}
            {{choice_ .}}    <!-- it should be {{choice_1}} and so on depends on the value of dot.
        {{/each}}
    {{/with}}
</template> 

Is it possible to concatenate a variable name as i am trying to do?

You should create a proper json for your data and then iterate directly through the values. For example:

Template.choices.choices = function() {
  var array = [];
  _.each(choices, function(choice, idx) {
    array.push({
      value: choice,
      idx: idx,
    });
  });
  return array;
};

 

{{#each choices}}
  {{value}}
{{/each}}
