The difference between span and div is that a span element is in-line and usually used for a small chunk of HTML inside a line (such as inside a paragraph) whereas a div (division) element is block-line (which is basically equivalent to having a line-break before and after it) and used to group larger chunks of code.

Define post method for sending the data to the server with an example.

Ans: Post method for sending the data is the non-idempotent method where we can send large amount of data because it is the part of the body. Example:

            Name<input type=”text” id=”uname” name=”uname”/><br/>

            Password<input type=”password” id=”pw” name=”pw”/>

            <input type=”submit” name=”submit” id=”submit” value=”Submit”/>

</form>

What do you mean by class selector? Give an example.

The .class selector selects elements with a specific classattribute. To select elements with a specific class, write a period (.) character, followed by the name of the class. You can also specify that only specific HTML elements should be affected by a class.

  • What are the uses of CSS? Explain combinators with example.

 CSS is the language for describing the presentation of Web pages, including colors, layout, and fonts. It allows one to adapt the presentation to different types of devices, such as large screens, small screens, or printers. CSS is independent of HTML and can be used with any XML-based markup language. The separation of HTML from CSS makes it easier to maintain sites, share style sheets across pages, and tailor pages to different environments.

CSS combinators are explaining the relationship between two selectors. CSS selectors are the patterns used to select the elements for style purpose. A CSS selector can be a simple selector or a complex selector consisting of more than one selector connected using combinators.
There are four types of combinators available in CSS which are discussed below:

    • General Sibling selector (~)
    • Adjacent Sibling selector (+)
    • Child selector (>)
    • Descendant selector (space)
  • General Sibling selector (~)

div ~ p{

color: #009900;

font-size:32px;

font-weight:bold;

margin:0px;

text-align:center;

}

 

  • Adjacent Sibling selector (+)

div + p{

color: #009900;

font-size:32px;

font-weight:bold;

margin:0px;

text-align:center;

}

 

  • Child selector (>)

div > p{

color: #009900;

font-size:32px;

font-weight:bold;

margin:0px;

text-align:center;

}

 

  • Descendant selector (space)

div   p{

color: #009900;

font-size:32px;

font-weight:bold;

margin:0px;

text-align:center;

}

 

  • Explain different HTTP methods. Why the web form should be validated? Write a JavaScript program to check whether user entered number is Prime or not.

 The most common HTTP methods are GET and POST.

The GET method:

  • GET is used to request data from a specified resource.
  • GET requests can be cached
  • GET requests remain in the browser history
  • GET requests can be bookmarked
  • GET requests should never be used when dealing with sensitive data
  • GET requests have length restrictions
  • GET requests is only used to request data (not modify)

The POST method:

  • POST is used to send data to a server to create/update a resource.
  • The data sent to the server with POST is stored in the request body of the HTTP
  • POST requests are never cached
  • POST requests do not remain in the browser history
  • POST requests cannot be bookmarked
  • POST requests have no restrictions on data length

The web form should be validated in order to take valid data from the user. It also helps us to ensure that users fill out forms in the correct format, making sure that submitted data will work successfully with our applications.

Source code:

<!DOCTYPE html>

<html>

<head>

    <title></title>

    <script type="text/javascript">

        function check()

        {

            var i;

            var count=0;

            var n1;

            var c=0;

            n1=document.getElementById('prime').value;

            for(i=2;i<n1;i++)

            {

                if(n1%i==0)

                {

                    c+=1;

                }

            }

            if(c==0)

                {

                    alert("The entered no. is prime");

                }

            else

                {

                    alert("The entered no. is not Prime");

                }

        }

    </script>

</head>

<body>

    <label>Enter Number </label><input type="number" name="number" id="prime">

    <button onClick="check()">Check</button>

</body>

</html>

Get vs. Post

There are many differences between the Get and Post request. Let’s see these differences:

GET POST
1) In case of Get request, only limited amount of data can be sent because data is sent in header. In case of post request, large amount of data can be sent because data is sent in body.
2) Get request is not secured because data is exposed in URL bar. Post request is secured because data is not exposed in URL bar.
3) Get request can be bookmarked. Post request cannot be bookmarked.
4) Get request is idempotent . It means second request will be ignored until response of first request is delivered Post request is non-idempotent.
5) Get request is more efficient and used more than Post. Post request is less efficient and used less than get.

– Create a HTML login form which includes username, password and repassword and validate it using java script.

                    function validate() {

                              var username=document.getElementById('username');

                              var password=document.getElementById('password');

                              var repassword=document.getElementById('repassword');

                              if(username.value==""||password.value==""||repassword.value==""){

                                        alert("Fields are Empty !!!");

                              }

                              if(password.value!=repassword.value){

                                        alert("Passoword doesnot Match !!");

                              }

                              if(password.value.length<8){

                                        alert("Password must be greater than 8 character.");

                              }
