Disable Enter key using javascript code

Here is the function to disable Enter keys using javascript code,  you have to paste this code and call this javascript method from your window onload method or using Jquery ready methods:


function DisableEnterKey(e) {
    var key;

    if (!e) {
        e = window.event;
    }

    if (e.keyCode) {
        key = e.keyCode;
    }

        key = e.which;
    }

    return (key != 13);
}

    {
        //loop will work for each form on the page
        for (f=0; f < document.forms.length; f++)
        {
           // for each element in each form
            for(i=0; i < document.forms[f].length; i++)
            {
              // if it's not a hidden element and it's not disabled
              if (document.forms[f][i].type != "hidden" && document.forms[f][i].disabled != true)
              {    
                    document.forms[f][i].focus();

Adding Facebok Login / Like / Logout button to Blogger / Website.

All the steps are same for adding facebook plugins like Like button / Login-Logout button , Comment Box etc. Only there is one step difference

Below are the steps with screenshot to embed the buttons on Blogger. 

Step 1 & Step 2:  Open your blog and log-in into it. Then you will see "Templates" menu in the left, Click on it and the step 2 is click on "Edit HTML" as shown in below screenshot:

Step 3:  Clicking on Edit HTML, We need to add namespace "xmlns:fb='http://ogp.me/ns/fb#'" as highlighted in below image. Once you add the namespace, Click on "Save Template" as highlighted.

Step 4: Once you save the template, click on "Layout" menu(3rd last) in the left menu list.

             This will open up a page as shown in below screenshot.

Click on "Add a Gadget" button wherever you wish to add facebook plugins. 

Clicking on "Add a Gadget" will open up a popup with multiple option of Gadgets as shown below:

from this popup, we have to select "HTML/Javascript" which is at 3rd last position in above screenshot.

This will further open up a popup as shown below, where we need to add below code snippet:

<div id="fb-root"></div>

<script>(function(d, s, id) {

  var js, fjs = d.getElementsByTagName(s)[0];

  if (d.getElementById(id)) return;

  js = d.createElement(s); js.id = id;

  js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&appId=694894273921188&version=v2.0";

  fjs.parentNode.insertBefore(js, fjs);

}(document, 'script', 'facebook-jssdk'));</script>

<div class="fb-like"   data-layout="standard" data-action="like" data-show-faces="true" data-share="true"></div>

The above code is for "Like" button only, if you want to add Login/Logout or comment plugin, you only need to change the highlighted div from above step only.

<div class="fb-like"   data-layout="standard" data-action="like" data-show-faces="true" data-share="true"></div>

You can get other plugins code from https://developers.facebook.com/docs/plugins

Step 5:

After saving this, popup will be closed. Then click on "Save Agreement" as shown in below figure.

Step 6: Yipeee!!! you are done, this will show you Facebook like button.

Set the value of one Textbox, Whenever the other textbox value changes using Jquery

Hi Everyone,

I am writing this article to help those who are very new to jquery,

Requirement is : Need to update one input box on changing the text in other text box.

Solution:  I am assuming that you know the basic of html and javascript.

Here is the text version of the code. you just have to copy the code and paste this text in notepad file and save that file as html.
------------------------Beginning of Code------------------------------------------------
<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $("#FirstInput").on('keyup', function () {
                $("#SecondInput").val($(this).val())
            });
        });
    </script>
    <title></title>
</head>
<body>

    <div>
    First InputBox <input type="text" id="FirstInput" value="" /> <br />
    Second InputBox <input type="text" id="SecondInput" value="" /> <br />
    </div>

</body>
</html>
------------------------------End Of Code-----------------------------------------------

After running this code, the output will be :

As you can see if i enter "G" in First InputBox the value will automatically be reflect in 2nd InputBox.
The Jquery Code which is doing all this is :

 $("#FirstInput").on('keyup', function () {
                $("#SecondInput").val($(this).val())
            });

$ is inbuild keyword to access elements using jquery and every function that need to be registered on element are to be enclosed in ready method of jquey as provided in code.

Happy Coding :)

    var prm = Sys.WebForms.PageRequestManager.getInstance();
    // Add initializeRequest and endRequest
    prm.add_initializeRequest(prm_InitializeRequest);


    // Called when async postback begins
    function prm_InitializeRequest(sender, args) {
    // get the divImage and set it to visible
    var panelProg = $get('divImage');
    panelProg.style.display = '';


    // Disable button that caused a postback

    }


  </script>
