Making Clone on Web Page using jQuery


Introduction

This post shows how to make the clone of elements on web page using jQuery, for this we will use .clone() method.

Sometimes we want to copy (clone) elements on web page, for example, navigate menu can be placed on header and footer too and there may be many situations come to us where we need to clone. Why write something twice if we have opportunity to use jQuery.

So, let's create a demonstration page for this talk.

<body>
    <h2>History of Visual Studio</h2>
    <div class="mainBody">
        Visual Studio's history probably begins in <strong class="year">1975</strong> with Bill and Paul's decision to create Altair BASIC.  Maybe you could start before that but I think that's as far back as you could go and still say it's about Visual Studio at all – it's at that time that Microsoft decided it was going to have software development products and not, say, toaster automation.
    </div>
    <p>
        Some informations.
    </p>
    <p>
        Some more informations.
    </p>
</body>

Let's assume; we want to copy the 'mainBody' <div> and place it after first <p>. To do this we will use following jQuery:

$('div.mainBody').clone().insertAfter('p:eq(0)');

Above jQuery, making the clone of <div> that has class 'mainBody' and inserting this new clone after first <p>, in DOM 0 refers the very first <p>, 1 refers the second <p> and so on.

Output in Browser:


Take one more assumption; what if we want to apply different style to cloned copy?

Now, to do this we need to create a style class.

    <style type="text/css">
        .cloneStyle {
            background: #ead3d3;
            font: italic 1.4em "Times New Roman", Times, serif;
        }
    </style>

So, we have a style now; let's add it to cloned copy.

$('div.mainBody').clone().insertAfter('p:eq(0)').addClass('cloneStyle');

Nothing new here, just added one more attribute .addClass('cloneStyle') to existing jQuery above.

Now, look at the output in browser:



So, that's all about the making clone on web page. You can dive deep in this topic to achieve some more functionality.

Migrating database from ASP.NET Identity to ASP.NET Core Identity

Image
As you know ASP.NET Core Identity (table structure) is different from what we had earlier in ASP.NET Identity. Actually the identity system which we have today with .NET Core is very mature and continuously evolved be it ASP.NET Membership, ASP.NET Identity 1, ASP.NET Identity 2 and now ASP.NET Core Identity. Recently I had to migrate few application to ASP.NET Core and similar its identity database. Because the table schema is changed, i had to re-think and create migration script which I would like to share with you today. It is very simple and easy, just three step and I had everything ready: STEP 1 : Change name of existing tables STEP 2 : Create ASP.NET Core Identity tables STEP 3 : Migrate data from old tables (ASP.NET Identity) to new tables (ASP.NET Core Identity) Script:  https://gist.github.com/itorian/c699e8534b392a6c726ec66c48100072 You should also watch my video, where I demoed migration.

Lambda two tables and three tables inner join code samples

In this blog post you will learn inner join using lambda queries. There will be two samples, in first sample you will see how you can join two tables and in second sample you will see how you can extend even further to join three tables and so on. I will sample in-memory data, but the same implementation will work with IQueryable (lazy query) too. Here's the code snippet:- namespace ConsoleApp1 {     class Program     {         static void Main()         {             var table1 = new List<Table1>();             table1.Add( new Table1 { Id = 1, Name = "Name 1" , Address = "Address 1" });             table1.Add( new Table1 { Id = 2, Name = "Name 2" , Address = "Address 2" });             table1.Add( new Table1 { Id = 3, Name = "Name 3" , Address = "Address 3" });             table1.Add( new Table1 { Id = 4, Name = "Name 4" , Address = "Address 4" });
