I have this block of code in a Spacebars template:
1.
<select class="form-group">
{{#each choices}}
<option>{{this}}</option>
{{/each}}
</select>
I would like to repeat this N times incrementing the number each time like so:
1.
<select class="form-group">
{{#each choices}}
<option>{{this}}</option>
{{/each}}
</select>
2.
<select class="form-group">
{{#each choices}}
<option>{{this}}</option>
{{/each}}
</select>
3.
<select class="form-group">
{{#each choices}}
<option>{{this}}</option>
{{/each}}
</select>
I would love to be able to pass N to a custom template tag to take care of this (e.g. {{choices 3}}). What's a nice DRY way to do this? I have a vague notion I could write a template helper, but I'm not sure where to start.

You can pass a count in and return an array of arbitrary objects. Not the most elegant... but it worked!
HTML
<body>
{{>content}}
</body>
<template name="content">
{{#each loopCount 5}}
<select class="form-group">
{{#each choices}}
<option>{{this}}</option>
{{/each}}
</select>
{{/each}}
</template>
JS
Template.content.helpers({
choices: function(){
return ['choice1','choice2','choice3']
},
loopCount: function(count){
var countArr = [];
for (var i=0; i<count; i++){
countArr.push({});
}
return countArr;
}
});
If you're using the underscore package for Meteor, and also happen to be using CoffeScript, you can create the following single-line template helper:
t.helpers
loop: (count) -> {} for i in _.range count
You can then use this helper in your template:
{{! Will display 'Output' 5 times }}
{{#each loop 5}}
Output
{{/each}}
