将文本框的值放入另一个文本框中

Question

I have a start date which is put in a textbox by the user trough a jquery date picker.
I also have an end date textbox which I want to fill with the start date value when the user changed the value of the start date.

So I was thinking of doing a JavaScript and than a when textbox has changed enter value into end date textbox but I don't know how this would be done.

Thank you guys for helping since I am new to JavaScript.

This is just the simple method below,but if you need something other,let me know

function copytextbox()
{
 document.getElementById('textbox2').value=document.getElementById('textbox1').value;

return false;

}
