I'm not a JS expert but I've been given a JSON model to display using jQuery, and have my hopes up for jQuery Templates. However all the documentation examples seem to be for simple 2-level arrays, and I can't translate these examples to the JSON I have. I'm not clear on whether I should be working with jQuery.tmpl(), or {{each}} or {{tmpl}} or {{wrap}} to iterate through this data.

I need to acquire the JSON below and display each "host" name followed by its "states" details (CPU, Disk, Mem.) Any hints on开发者_开发技巧 how to proceed are much appreciated.

{"health":64,
"hosts":[
        {
        "name":"Windows2000P",
        "states":[
            {"name":"CPU","link":"(html link)","bgcolor":"#CC99CC"},
            {"name":"Disk","link":"(html link)","bgcolor":"#CC99CC"},
            {"name":"Mem","link":"(html link)","bgcolor":"#CC99CC"}
            ]
        },
        {
        "name":"Windows2003",
        "states":[
            {"name":"CPU","link":"(html link)","bgcolor":"#98FB98"},
            {"name":"Disk","link":"(html link)","bgcolor":"#98FB98"},
            {"name":"Mem","link":"(html link)","bgcolor":"#F08080"}
            ]
        },
        {
        "name":"Windows7",
        "states":[
            {"name":"CPU","link":"(html link)","bgcolor":"#98FB98"},
            {"name":"Disk","link":"(html link)","bgcolor":"#98FB98"},
            {"name":"Mem","link":"(html link)","bgcolor":"#F08080"}
            ]
        }
    ]
}


Here's an example of the kind of template you might use:

<script type="text/x-jquery-tmpl">
  <h2>${health}</h2>

  {{each hosts}}
  <h3>${name}</h3>

  <ul>
    {{each states}}
    <li style="background-color: ${bgcolor};"><a href="${link}">${name}</li>
    {{/each}}
  </ul>
  {{/each}}
</script>
