1. Write a JavaScript function to validate a text-field on a form that is to hold an email address. Now when writing this JavaScript function bear in mind that you won't be able to fully validate it unless you manage to interrogate the server in which it's supposed to reside.This is almost impossible, so the validation should check that the contents of the text-field only looks like a valid email address.
email addresses look like the following
[email protected]
[email protected]
[email protected]
[email protected]
etc ...

Submit a html file with a form containing an email text-field, and the JavaScript code that called to validate the text-field when the form is submitted. (so I can easily test it).

2. Write a JavaScript function to validate a text field on a form which is to contain an integer, eg 2, 4567, 87612etc ... without using any built functions like IsNaN an so fourth.If the text field contains a valid number then the JavaScript function can return "true", otherwise it returns "false" as well as displaying a popup error message.

3. You have a server-side script that cannot handle any ampersands (&) in the form data. Write a function that converts all ampersands in a form field to " and " when the field loses focus (onblur).
