DHTML page which accepts user input into the text field as integers. when the user pressed the "Display" button, your function created in javascript should able to display the sum of the entire integers in an alert message.
Example
Input :
"21547524"
Output:
"2+1+5+4+7+5+2+4 = 30"
var input="21547524";
var additions=input.split('').join('+');
alert(additions+' = '+eval(additions));

I need to write a JavaScript function which accepts IP range or subnets and validate it.
Like 10.0.0.1/24 should return true
10.0.0.1-10.0.0.10 should return true.
Use:
((\b|\.)(1|2(?!5(?=6|7|8|9)|6|7|8|9))?\d{1,2}){4}(-((\b|\.)(1|2(?!5(?=6|7|8|9)|6|7|8|9))?\d{1,2}){4}|\/((1|2|3(?=1|2))\d|\d))\b

This one also allows leading zeros:
((\b|\.)(0|1|2(?!5(?=6|7|8|9)|6|7|8|9))?\d{1,2}){4}(-((\b|\.)(0|1|2(?!5(?=6|7|8|9)|6|7|8|9))?\d{1,2}){4}|\/((0|1|2|3(?=1|2))\d|\d))\b

Let us consider we have a function for validating all fields in the form. If I am changing the input of one particular field, the only field that has been changed should be validated but not other fields.
If you are using jQuery, you can use .bind() function to trigger on the change of the input box.
$("element").bind('change', function({}));

Suppose I have a number like 1234. I want to add new number 00 and , and € at the end. Now number will be like 1234,00€ I can not figure out.
That will work for you:
var value = '1234';
var formatted = value.replace(/(\d+)/, '$1,00€');
But, I strongly recommend you to read the answers in this question: How can I format numbers as money in JavaScript?
Update as #jared said, you can just concatenate the text: ,00€ to your number to just get the desired results.
