Question

I am using jQuerys “tmpl” plugin for templates. Now i have an array with elements that are arrays as well and i have to access specific elements.

i.e. the array would be:

var arr = {
  'id':23422,
  'title':'example',
  'images': {'small':'34fge.jpg','original':'dfsdf354.jpg'}
};

And now in the temple i’d like to access arr[images][small] but it doesn’t work. What i am trying is:

<div>
  <h3>${title}</h3>
  <img src="${arr}{images}{small}" />
</div>

Anyone any help/ideas?

Answer 1

Use <img src="${images.small}" /> that will give the following markup:

<div>
  <h3>example</h3>
  <img src="34fge.jpg">
</div>

In fact, the images property isn’t a nested array but a object with properties.

But if you really want to loop through a nested array, then you should use a nested template and change your syntax a little bit (note the [] around images property):

Javascript

var arr = {
    'id': 23422,
    'title': 'example',
    'images': [
        { 'small': '34fge.jpg', 'original': 'dfsdf354.jpg' },
        { 'small': '35fge.jpg', 'original': 'dfsdf.jpg' }
    ]
};

Templates

<script id="template" type="text/x-jquery-tmpl">
   <div>
     <h3>${title}</h3>
     {{tmpl(images) "#imagesTemplate"}}
   </div>
</script>
<script id="imagesTemplate" type="text/x-jquery-tmpl">
     <img src="${small}" />
     <img src="${original}" />
</script>
