],
css: [
'/_modules/helloworld/_views/helloworld.css'
],
widgets: {
pnelopnavbar: {
placeMarker: '#leftColumn',
data: {},
options: {},
jsobject: 'helloWorld',
id: 'helloWorld_navBar',
process: 1,
js: [],
css: []
}
},
options: {}
);
*
* Javascript Implentations
* Create boot data
* 1. create javascript Layout Packet, in this case we are using above example as _layoutPacket
* 2. create javascript variable for boot data, eg. var bootData = {};
* 3. add layout object as an array to boot data variable, eg. bootData = { layout: [] };
* 4. push Layout Packet to boot data layout object array, eg. bootData.layout.push(_layoutPacket);
*
*
* Plan A only works if using the pnelop backend framework
* Plan B is used when the page first loads, view source will show the user this data, no matter what page they are on
* Plan C is typically used to change pages, can be used for page loading in place for Plan B
*
* Implementation Examples / Suggestions
* Plan A) using pnelop framework, pnelop.fetchPage(<url (optional, default: location.href)>);
* 1. send URL to pnelop.fetchPage() after page loads eg. $.(document).ready(function() { pnelop.fetchPage(); });
*
* Plan B) load boot data with html, send bootData to pnelop.bootBIOS
* 1. send boot data to the browser, using above example in script tags, eg.
<script type="javascript">
var bootData = { layout: [
{
// Layout Packet
},
{
// Second Layout Packet, (Optional)
}
]};
</script>
* 2. send bootData variable to pnelop.bootBIOS.
* - Required to happen AFTER bootData is shown in browser.
* - Required AFTER page loads
* Plan A) by using jQuery eg.
* $.(document).ready(function() { pnelop.bootBIOS(bootData); });
* Plan B) by either placing following example inside <body> tag, eg.
* <!-- <script language="javascript">pnelop.bootBIOS(bootData);</script> -->
*
*
* Plan C) using a Manual AJAX Request, sending reply to pnelop.bootBIOS
* 1. run AJAX Request $.getJSON() works well, Reply with above boot data as JSON Encoded Object.
* Expected response has "Content-Type: application/json"
* 2. send boot data response to pnelop.bootBIOS()
*
*
*
*
*
* PHP Example -> JSON Encode, add to GET Response in object boot data object 'layout', eg. echo json_encode($arrLayoutPackets);
$arrLayoutPackets = new Array(); // Build layout object as array for Layout Packets
// Basic PHP Layout Template
$arrLayout = new StdClass; // New Layout Package
$arrLayout->pageLayout = 'single'; // single, single_left, single_right, triple
$arrLayout->pageWidths = '*'; // Comma Seperated (single_left: '164,*') (triple: '164,*,250')
$arrLayout->modals = array();
$arrLayout->js = array();
// $arrLayout->js[] = $v4config->site['_modules'].'helloworld/'.$v4config->site['_view'].'helloworld.js';
$arrLayout->css = array();
// $arrLayout->css[] = $v4config->site['_modules'].'helloworld/'.$v4config->site['_view'].'helloworld.css';

$arrLayout->widgets->pnelopnavbar = $pNelOP_Widget; // Add Widget Package to Layout Package
// Add Generated Layout to Layout Packets array.
// Multiple packets are accepted, push them into the Layout Packets array
