Hola, amigos, este es mi primer mensaje aca en el foro y es para pedir desesperadamente ayuda.
Estoy estudiando en Estados Unidos y me meti a una clase de Javascripting (nada tiene que ver con mi carrera pero ya que la curso, necesito aprobarla) y Html pero la verdad es que no entiendo nada y necesito sacarme esta materia de encima lo antes posible.
Me mandaron una tarea que tengo que hacer urgente y no tengo idea de como hacerla. Yo se que es poco etico y moral y todo pero necesito si alguien con 10 minutos (se que no es muy dificil puede ayudarme). Se los voy a agradecer de por vida.
Aca les dejo las pautas (en ingles):
Desde ya, mil gracias!
Part 1: (10)
1. Create an HTML document with a head, a title and a body with the
following name: part1.html
2. Make the title JavaScript Assignment 4 Part 1.
3. In the body, display the following message: "Welcome to the
temperature calculator!"
4. Write a JavaScript program that does the following:
5. Prompts the user for the temperature in Farenheit using a pop up
window with the text "Please enter temperature in Farenheit:". The
default text in the pop-up input field should be 0.
6. The program converts the temperature to Celcius, closes the popup
window and displays the converted temperature in the original window
with the text: "The corresponding temperature in Celsius is:" -- no
other buttons or text should be present. The converted temperature
should be rounded off.
7. The formula to do the conversion is:
Tc = (5/9)*(Tf-32);
Tc = temperature in degrees Celsius,
Tf = temperature in degrees Fahrenheit
Part 2: (10)
1. Create an HTML document with a head, a title and a body. with the
following name: part2.html,
2. Make the title JavaScript Assignment 4 Part 2..
3. In the body, display the following message "Welcome to the Grades
Report!"
4. Write a JavaScript program that does the following:
5. Prompt the user for the grades of 10 students with one prompt for
each grade with the prompting text being: "Enter grade between 1 and
10 for student n:" where n varies from 1 to 10. If the grade input is
not between 1 and 10, please prompt again for the grade.
6. Once the user is done, it prints a report telling you the grade of
each individual student and the average of the ten grades. The
individual student grade should be in different lines with the text
"Grade for student n is x". The average should also be in a different
line with the text "Average grade is y". The average grade should not
be rounded off.
Part 3: (20)
1. Create an HTML document with a head, a title and a body with the
following name: part3.html.
2. Make the title JavaScript Assignment 4 Part 3.
3. In the body, display a welcome message like "Welcome to Switching
Images!"
4. Write a JavaScript program that operates as follows: the document
displays an image when first loaded on the browser. When this image
is clicked, the image is replaced by a second image. When the second
image is clicked, the image is replaced by the first image. In other
words, every time an image is clicked, the image is replaced by the
other.
5. Use the following two images:
USEN CUALQUIER IMAGEN
USEN CUALQUIER IMAGEN
Hint 1:
In this example below, the document displays an image when first loaded on the browser. When this image is clicked, the image is replaced by a second image. However, in this example, when the second image is clicked, nothing further happens.
<html>
<head>
<title>Image switch</title>
<script language="Javascript">
//The function is called when the image in the body is clicked. The function changes the image source of 'picture' to 'a2.jpg'
function rollover ()
{
document.picture.src = "a2.jpg";
}
</script>
</head>
<body>
<!-- there is an image tag below with the name picture that displays 'a1.jpg'. When the image is clicked, the 'rollOver()' function is called
-->
<img src="a1.jpg" name="picture" border="0" onClick="rollover()"> </body> </html>
Hint 2:
Use string comparison to check the value of document.picture.src in order replace one image by another and vice versa.
