If I want to show the result of a database query, every second or so, is the best method using javascript/ajax with a set interval of a second to call a PHP script and update the DOM, or is there some other method better suited to this that would not have the cpu overhead if there were many users on the site.

I'm making a little CMS, and I need to use AJAX to query the DB to see if an email is already registered. Here's my code so far:
The javascript:
Code:
<script>
function getEmail(){
var ajaxRequest;
try{
ajaxRequest = new XMLHttpRequest();
} .....
I'll test it by entering javascript:alert(getEmail()) in my browser, and it returns undefined. When I replace return 'valid/taken' to alert valid/taken, it will alert the values correctly, but for some reason it has to be entered twice (I have to hit enter twice in javascript:getEmail() for it to be correctly outputted). I'm relatively new to ajax and I think it might have something to do with the readyState not being correct.
I am making a webpage that can query a database table of employees
and return them in a html table. Currently I have submit buttons beside
each employee to open the page to edit their details. I have been using
php/HTML to do this, but wondered if it is safe to use javascript to
just click on the name of the employee to jump to the edit page. I've
been looking on the web for sometime about how to do this without any
luck. Any thoughts?
Looking for a way to show/hide the parent of a class of elements:
Code:
But FF is giving the error message "'elP.parentNode' undefined". Something I'm not getting.
does 'focus' method show a 'stable' result? i call this method on a node if this one is not absolutely positioned it seems nothing happens.so does this method only apply to absolutely positioned element?also, in FF, aNode.focus() has no effect whereas in IE document will scroll until that node is visible if the node is partially invisible at the bottom.is this a bug in FF?scroll the document until the text is half-visible at the bottom. click on it in IE it will scroll up while in FF nothing happens besides, if it is not absolutely positioned, nothing happens either.

All works fine with that, however... I have created another page which retrieves the results for an individual's form submission, and I want to hide the sections that were not completed (hidden when submitted).

I am doing a lottery project in which i have 10 textbox and i want to add contents of each textbox and show result in another textbox say 11th textbox.
I am having the fallowing codes below on jsp page.
I want to add contents of textbox from(n50,n51.....n59) and show result in another textbox named (n60)
My question is that the valus stored in textbox is numeric and when i enter the value in any two of the textbox say named (n50 and n51) then the addition of its value must be seen in the result textbox say (n60) here. it does not wait for another textbox value which is left blank. the result of addition should be displayed simelteneously as i enter the value in text box.
Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section.
