PHP is executing a javascript on mouse move over window. It's looping on a function. How can I make it execute only once?
Question
Basically, I have to execute a function on JS, that uses a variable in PHP. The problem I'm having is that the function on JS is executing constantly. I need the function to execute when the mouse moves over the page, which works great, except it executes in loop non-stop.
I'm pasting an example code. Any ideas on how to make it execute the JS function only once? Any help would be greatly appreaciated, I'm not very good at PHP & JS.
<?php
function page()
{
echo 'test text';
}
//page()
?>
<html>
<head>
<title>onmousemove test</title>
<script type="text/javascript">
window.onmousemove = move;
function move() {
alert("<?PHP page() ?>");
}
</script>
</head>

Use a flag. check if the flag is set, if not, execute the code, then set the flag.
var stop = false; //flag
function move(){
if(stop) return; //is the flag true?
alert("<?PHP page() ?>"); //it wasn't, so alert
stop = true; //now set it to true so it doesn't fire again
}

It's not looping non-stop, it's just looping whenever you move your mouse... You should consider window.onload instead, this fires automatically when the page is done load. But since in this post you insist window.onmousemove , you can try this:
triggered = false;
function move() {
triggered = true;
alert("<?php page(); ?>");
}
window.onmousemove = function(){
if (triggered === false) move();
};
