Write a JavaScript function to handle a callback:

Assume the following input fields:

<input type=“text” id=“lastName” name=“lastName” />
<input type=“text” id=“firstName” name=“firstName” />
<input type=“text” id=“phone” name=“phone” />
<input type=“text” id=“email” name=“email” />

A callback function will receive a pipe delimited string from the server as such:


Example: Doe|Jane|415-555-1212|jane.doe@gmail.com

The callback function is:

function customer_Callback ( content )
// use the split method to convert content to an array.
// use document.getElementById() to get each of the above input fields.
// populate from the array.

I am having serious trouble with these problems: Please help me, I beseech you!

It wouldn’t be right or appropriate for us to do the equivalent of a homework assignment for you, so is there anything inparticular that you would like us to help you understand?

What’s the difference between explicit and implicit? I can’t seem to find the answer anywhere.

That might be a potential clue as to the nature of the answer.
