Write a javascript program according to the follow requirements:

Create a function that converts Fahrenheit to Celsius. It takes a single argument which represents degrees in Fahrenheit. It converts it and returns the degrees in Celsius.
Create another function that converts Celsius to Fahrenheit. It takes a argument in Celsius and returns the degrees in Fahrenheit.
Implement the function convert(isFtoC, from, to) below. It takes the following three arguments:
- isFtoC: a boolean that is true if degrees must be converted from Fahrenheit to Celsius or false if degrees must be converted from Celsius to Fahrenheit
- from: this represents the first value in a range of degrees that will be converted
- to: this represents the last value in a range of degrees to be converted
The function must convert every degree in the specified range and show each degree and the converted result on the page. Call show(str) to display a string on the page.

function convert(isFtoC, from, to) {
// your code here
}

Note: Use .toFixed(2) to limit the decimal digits to 2, e.g. num.toFixed(2)

Expert Solution

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new web page with name "tempConversion.html" is created, which contains following code.

tempConversion.html :

<!DOCTYPE html>

<head>

<title>Temprature Conversion</title>

</head>

<body>

From Temp :<input type="text" id="txtFrom"/>

To Temp :<input type="text" id="txtTo"/>

Select Conversion :

<option selected>--Select Conversion--</option>

<option value="Fahrenheit">Fahrenheit</option>

<option value="Celsius">Celsius</option>

</select>

//function to convert temprature

function convertTemp()

{

var from=parseFloat(document.getElementById("txtFrom").value);//take from temp

var to=parseFloat(document.getElementById("txtTo").value);//take to temp

//checking what is selected

if(document.getElementById("temp").value=="Fahrenheit")

{

//if Fahrenheit is selected

convert(true,from,to);

}

else{

//if Celisus is selected

convert(false,from,to);

}

//function to convert Fahrenheit to Celsius

function fToC(f)

{

return (f-32)* 5/9;//return temp in c

}

//function to convert Celsius to Fahrenheit

function cTof(c)

{

return (c*9/5)+32;//return temp in f

}

//function to convert temprature

function convert(isFtoC, from, to)

{

var tempStr="";

//checking if Fahrenheit to Celsius

if(isFtoC==true)

{ tempStr="F:C<br/>";

//convert temprature in Fahrenheit

for(var i=from;i<=to;i++)

{

tempStr+=i+" : "+fToC(i).toFixed(2)+"<br/>";//call function and concate

}

show(tempStr);//call function to display details

}

else if(isFtoC==false){

tempStr="C:F<br/>";

for(var i=from;i<=to;i++)

{

tempStr+=i+" : "+cTof(i).toFixed(2)+"<br/>";//call function and concate

}

show(tempStr);//call function to display details

}

//function to show string

function show(str)

{

document.getElementById("myDiv").innerHTML=str;//display on the div

}

</script>

</body>

</html>

======================================================

Output : Compile and Run tempConversion.html in the browser and will get the screen as shown below

Screen 1 :tempConversion.html

Screen 2 :Temp from f to c

Screen 3 :Temp from c to f

NOTE : PLEASE FEEL FREE TO PROVIDE FEEDBACK ABOUT THE SOLUTION.
