Question

id like to create an array storing:

document title
document summary
document link

and then loop through each entry, displaying each in the html.

so far ive got my array..:

var docs = [
{
    doc-title: "onesider number 1",
    doc-info:    "its onesider number 1",
    doc-src: "link here"
},

{
    doc-title: "Onesider number 2",
    doc-info:    "its onesider number 2",
    doc-src: "link here"
}

];

but after this I have no idea how to loop and display each. any suggestions?

You are asking two questions at a time:

• how to loop in javascript
• how to append data —from that loop— to the DOM

You can check this question about loops in javascript, the each() function in jQuery, also take a look at append, prepend, text, html, attr functions in jQuery documentation.

Here is probably what you are trying to achieve (assuming you are using jQuery) :

var docs = [
    {
        docTitle: "onesider number 1",
        docInfo:    "its onesider number 1",
        docSrc: "link here"
    },
    {
        docTitle: "Onesider number 2",
        docInfo:    "its onesider number 2",
        docSrc: "link here"
    }
],

// This should be your items container  
container = $('#documents');


$.each(docs,function(i,doc){

    // Let's create the DOM
    var item = $('<div>').addClass('item'),
        title = $('<h1>'),
        info = $('<p>'),
        link = $('<a>');

    // Add content to the DOM
    link.attr('href',doc.docSrc)
    .text(doc.docTitle)
    .appendTo(title);

    info.text(doc.docInfo);

    // Append the infos to the item
    item.append(title,info);

    // Append the item to the container
    item.appendTo(container);
});

With this base html :

<div id="documents"></div>

you should end-up with something like :

<div id="documents">
  <div class="item">
    <h1><a href="link here">onesider number 1</a></h1>
    <p>its onesider number 1</p>
  </div>
  <div class="item">
    <h1><a href="link here">onesider number 2</a></h1>
    <p>its onesider number 2</p>
  </div>
</div>
