Clean Popover With Smart Position - jQuery gpopover

gpopover is a small clean jQuery popover plugin that has the ability to check and reposition the popover elements if they're out of the viewport.

How to use it:

1. First you need to load the latest jQuery library, and then include the stylesheet jquery.gpopover.css and script jquery.gpopover.js on the webpage.

<link href="jquery.gpopover.css" rel="stylesheet">
<script src="jquery.min.js"></script>
<script src="jquery.gpopover.js"></script>

2. Create the popover content which can be located wherever you like in the page markup.

<div id="popover-content" class="gpopover">
  Popover Content Here
</div>

3. Attach the popover content to a trigger element using the data-popover attribute:

<button id="trigger-example" data-popover="popover-content">
  Click Me
</button>

4. Specify the width of the popover. Default: 250px.

$('#trigger-example').gpopover({
  width: 300
});

5. Customize the duration of fadeIn and fadeOut animations.

$('#trigger-example').gpopover({
  fadeInDuration: 65,
  fadeOutDuration: 65
});

6. Prevent click within the popover from being propagated to the document (and thus stop the popover from being hidden). Default: false.

$('#trigger-example').gpopover({
  preventHide: true
});

7. Set the space between the popover and screen edge. Default: 10px.

$('#trigger-example').gpopover({
  viewportSideMargin: 20
});

8. Callback functions which will be fired when the popover is shown and hidden.

$('#trigger-example').gpopover({
  onShow: function() {},
  onHide: function() {}
});

9. Customize the apperance of the popover by overring the default CSS styles:

.gpopover {
  background-color: #FFF;
  border: 1px solid #CCC;
  border-color: rgba(0, 0, 0, 0.2);
  border-radius: 2px;
  box-shadow: 0 2px 8px rgba(0, 0, 0, 0.1);
  display: none;
  padding: 12px;
  position: absolute;
  z-index: 998;
}

.gpopover .gpopover-arrow {
  border: 8px solid transparent;
  border-bottom-color: #FFF;
  border-top-width: 0;
  height: 0;
  position: absolute;
  width: 0;
  z-index: 999;
}

.gpopover .gpopover-arrow-shadow {
  border: 8px solid transparent;
  border-bottom-color: #C0C0C0;
  border-bottom-color: rgba(0, 0, 0, 0.275);
  border-top-width: 0;
  height: 0;
  position: absolute;
  width: 0;
  z-index: 997;
}
