This Javascript function validates an email address field in a form. It uses a regular expression to test the email address against a pattern to check for a valid format. If the test fails, an alert is displayed and the form submission is cancelled by returning false. The function is called on form submission, passing the form ID and email field name to validate just that field.

This document contains JavaScript code to display an image based on the selected radio button. The code loops through the radio buttons, checks which one is selected, and uses that selection to determine the image filename by appending the numeric value to the file path. It then writes the corresponding image to the document with set width and height.
Adding text to an image by karan chananakaran chanana
This code allows you to add text to an existing image file. It takes the text string to add, selects a font size, calculates the width and height of the text, loads the image, allocates color for the background and text, places the text on the image at specific coordinates, and outputs the new image with text added. The text is overlaid on the bottom right of the original image.
Accessing data from a simple post by karan chananakaran chanana
This document provides examples of accessing data submitted via a POST request in PHP. It shows how to echo username values from $_POST, $_REQUEST, and $HTTP_POST_VARS superglobals. It also demonstrates accessing nested array values submitted in a POST form.
This PHP code takes an existing image file, pig.jpg, and adds text to it. The text "Happy Valentine" is added in red using the Verdana font at a size of 10 pixels and positioned at coordinates 25, 110 pixels on the image. The modified image is then output as a PNG file to allow it to be displayed in the browser with the text overlayed on the original image.
This document contains JavaScript code that uses try and catch blocks to handle errors. When a button is clicked, a function is called that tries to display an alert, but includes error handling using catch to detect any issues and display a custom error message alerting the user and including the error description.
Java script while loop by karan chananakaran chanana
This document demonstrates a JavaScript while loop that iterates through a block of code as long as a condition is met. The code defines a function called myFunction that is executed when a button is clicked. It initializes a variable i to 0 and uses a while loop to add the text "The number is" plus the value of i to a string x as long as i is less than 5. After each iteration, i is incremented by 1. After the loop, the string x is displayed in a paragraph with id="demo".
How to: Join Multiple Strings (C# Programming Guide)
string two = "karan";
string str = "chanana " + karan + "k";
System.Console.WriteLine(str);
The following code uses the Append method of the StringBuilder class to join three strings without the chaining effect of the + operator.
class StringBuilderTest
{
static void Main()
{
string karan = "karan";
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("chanana ");
sb.Append(karan);
sb.Append(" k");
System.Console.WriteLine(sb.ToString());
string str = sb.ToString();
System.Console.WriteLine(str);
}
}
