Sharepoint 2013 Search - Adding a hover panel to a content search webpart display template.

In sharepoint 2013 there is a new powerful webpart called Content By Search Webpart which is a substitute  of CQWP and also get rids of XSLT and uses search instead.

In Content Search WebPart there are in total 7 default display templates like Two Lines, Video,Picture on top 3 lines on bottom etc.

But all of the these template does not have a hover panel like we see in a search results. See below image

So to add hover panel to content search display templates we need to customize the template.

Open designer.
1.Go To >> All files >> _catalogs >> master page >> display templates >> content webparts >> your template ( in my case item_pictureontop.html)
2. right-click, and select Edit File in Advanced Mode:
3. Paste this code at the top as shown in the image below:

var id = ctx.ClientControl.get_nextUniqueId();
var itemId = id + Srch.U.Ids.item;
var hoverId = id + Srch.U.Ids.hover;
var hoverUrl = "~sitecollection/_catalogs/masterpage/Display Templates/Search/Item_Site_HoverPanel.js";
$setResultItem(itemId, ctx.CurrentItem);
ctx.currentItem_ShowHoverPanelCallback = Srch.U.getShowHoverPanelCallback(itemId, hoverId, hoverUrl);
ctx.currentItem_HideHoverPanelCallback = Srch.U.getHideHoverPanelCallback();

Notice I am using the out-of-the-box Item_Site_HoverPanel.js .As i want my results to display like a site item.You can use any OOTB hover js file or you create new one also.

4. Next, scroll down to the main <div> and change the id to use _#= $htmlEncode(itemId) =#_

Add the following code to that very same <div> tag:

onmouseover="_#= ctx.currentItem_ShowHoverPanelCallback =#_" onmouseout="_#= ctx.currentItem_HideHoverPanelCallback =#_"

5. Now add the following <div> after the first <div>:

<div id="_#= $htmlEncode(hoverId) =#_" class="ms-srch-hover-outerContainer"></div>

Inside this div the hover content will be rendered for each item.

Save the changes to the template.

This is how we can add a hover panel to content search webpart display templates.

CSS + Center align HTML element content using CSS

In case we need to center align HTML element content using CSS.
Using below ways we can do it.

1. If element contains text, then we can do it using text-align property
text-align:center;

2. If element contains child HTML elements inside it.
position:relative;
float:left;
left:50%; 

Sharepoint 2013 - Get all Site templates using Client object model

Code to get all site templates both inbuilt and custom site template ID using CSOM.


var templateCollection ;
function GetWebTemplates()
{

var context = new SP.ClientContext.get_current();
var web = context.get_web();

templateCollection = web.getAvailableWebTemplates(1033, false);

context.load(templateCollection);
context.executeQueryAsync(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed));
}

function success() {

var Templates = "";
var siteTemplatesEnum = templateCollection.getEnumerator();

while(siteTemplatesEnum.moveNext())
{
var siteTemplate = siteTemplatesEnum.get_current();
Templates +=  siteTemplate.get_name() +   ',';
}

alert("Site Templates - " + ',' + Templates);
}

function failed(sender, args) {
alert("Failed");
}

While you can get all the inbuilt site template ID from below link

https://www.nothingbutsharepoint.com/sites/devwiki/sp2010dev/pages/site%20templates%20in%20sharepoint%202010.aspx

And custom site template would have a format like this.

{GUID}#TemplateName

Sharepoint 2013 - Create a site from a custom site-template using client object model

Here, is the code to create a site from a custom site-template using CSOM.

function CreateSite() {

        //load site

   var currentcontext = new SP.ClientContext.get_current();

   var currentweb = currentcontext.get_web();

   //site object

   var webCreateInfo = new SP.WebCreationInformation();

   //set values

   webCreateInfo.set_description("This site is created from CSOM");

   webCreateInfo.set_language(1033);

   webCreateInfo.set_title("My Title");

   webCreateInfo.set_url("/myURL");

   webCreateInfo.set_useSamePermissionsAsParentSite(true);

   webCreateInfo.set_webTemplate("MyTemplateID");

   //add sub site

   this.NewWebsite = this.currentweb.get_webs().add(webCreateInfo);

   //Load and execute query

   currentcontext.load(this.NewWebsite, 'ServerRelativeUrl', 'Created');

   currentcontext.executeQueryAsync(Function.createDelegate(this, this.Success), Function.createDelegate(this, this.oncListQueryFailed));    

}

function Success() {

alert(this.NewWebsite.get_serverRelativeUrl());

}

function oncListQueryFailed(sender, args) {

    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());

}

Template ID is the most important thing here.It defines what is the type of site we are creating like would it be a Team Site,Blank Site, Wiki, Blog etc.
We can find all default template ID from here 
https://www.nothingbutsharepoint.com/sites/devwiki/sp2010dev/pages/site%20templates%20in%20sharepoint%202010.aspx

But , since here we are using our own custom site template . So we can get our template id from the code given in this blog.

Get web-template

Your custom site template id would  be in this format.
{GUID}#TemplateName
