jQuery URLive

URLive is a jquery plugin that helps you create an preview snippet of a url based on the Open Graph properties of the page, similar to a url preview in a facebook post.

The plugin works with any element that has a url content or value, even on <a> tag with href. It is lightweight and doesn't require any back-end code as data scraping is done asynchronously with AJAXusing the Yahoo Query Language (YQL).

4. OPTIONS

In jQuery Urlive you can pass the following options to customize the preview behavior and functionality.

5. CALLBACKS

You can define a callback function like this:

$(selector).urlive({
  callbacks: {
    onStart: function() {
      //execute this when urlive AJAX request starts
    }
  }
})

And here is list of callback functions you can define and execute on a given instance.

6. METHODS

When you call a method you can either use the element that you've applied theurlive preview or the container of the preview snippet.

7. STYLING

You can style the preview snippet using the jquery.urlive.css file which contains the default style. The display orientation primarily depends on the image size, you can set the size orientation with the imageSize option. If the image is large the image will be displayed on top and will occupy the width of the preview snippet. If the image is set to small the image will be displayed on the left side before the text details.

There are also data by default not being displayed, these are the site_name and type. If you want to show these data, you can edit this line and set the display property to block.

.urlive-sitename, .urlive-type {
  display:none;
}
