Php file calling in javascript failed

The PHP file cannot be called in javascript. The help environment is the javascript code in linux $ ('# send '). click (function () {& nbsp; $. get ('send. php', {& nbsp;}) ;}); send is the ID of a button of mine. you need to click this but the php file cannot be called in javascript.
The environment is in linux
Code in javascript

$ ('# Send'). click (function (){
$. Get ('send. php ',{
});
});

Send is the ID of a button. you need to click this button to call send. php.


Code in send. php
$ Send = $ _ GET ['send'];
If (isset ($ send )){
$ R = exec ("./copy ");
Echo $ r;
}

Copy is a simple C file that has been tested by gcc-o in linux. it must be okay.


However, if I click a button, the copy operation cannot be triggered.

------ Solution --------------------
Didn't you pass the send parameter?

You can use firebug.

JScript code

// Try $ ('# send') in this way '). live ("click", function () {send = $ ('# mes '). val (); $. get ('send22. php ', {send: send}, function (data) {alert ("send OK ");});});
