Mustache , iterating over JSON objects

Question

I have a JSON array of objects, and am trying to work out how to display them in Mustache.js. The array can be variable in length and content.

Example:

[ Object { id="1219", 0="1219", title="Lovely Book ", url= "myurl} , Object { id ="1220" , 0="1220 , title "Lovely Book2" , url="myurl2"}]

Ive tried:

        $.getJSON('http://myjsonurl?type=json', function(data) {
        var template = $('#personTpl').html();
        var html = Mustache.to_html(template, data);
        $('#test').html(html);

and the template:

 <script id="personTpl" type="text/template">
TITLE: {{#data}} {{title}} IMAGE: {{image}}
<p>LINK: <a href="{{blogURL}}">{{type}}</a></p>  {{/data}} 
</script>

but that doesn't display anything.

I've tried putting the JSON into an array, and then accessing it directly using products[1] something like this:

$.getJSON("http://myjsonurl?type=json", function(json) 
{
    var products = [];

    $.each(json, function(i, product)
    {           
            var product =
            {           
                Title:product.title,
                Type:product.type,
                Image:product.image             
            };

            products.push(product);
        ;       
    });     

    var template = "<h1>Title: {{ Title }}</h1> Type: {{ Type }} Image : {{ Image }}";


    var html = Mustache.to_html(template, products[1]);
    $('#json').html(html);                      

}); 

which will display one record fine, but how can I iterate over them and display all ?

Answer 1

You need a single JSON object that looks like:

var json = { id:"1220" , 0:"1220", title:"Lovely Book2", url:"myurl2" };
var template = $('#personTpl').html();
var html = Mustache.to_html(template, json);
$('#test').html(html);

So something like this should work:

$.getJSON('http://myjsonurl?type=json', function(data) {
var template = $('#personTpl').html();
$.each(data, function(key,val) {

        var html = Mustache.to_html(template, val);
        $('#test').append(html);
});

});

Answer 2

For your template to work the way you have it, your json needs to look like this

{
  "data": [
    { "id":"1219", "0":"1219", "title":"Lovely Book ", "url": "myurl"},
    { "id":"1219", "0":"1219", "title":"Lovely Book ", "url": "myurl"},
    { "id":"1219", "0":"1219", "title":"Lovely Book ", "url": "myurl"}
  ]
}
