jquery请求不止一次运行

Question

I have this code to make a request to a file that process some xls files ( with phpexcel library ) :

$("#applyCalls").click(function(){
    $.get("admin/processCalls.php");
});

the processCalls.php looks like this:

include '../phpexcel2/Classes/PHPExcel.php';
include '../phpexcel2/Classes/PHPExcel/IOFactory.php';
date_default_timezone_set('Europe/Bucharest');

$fisierInbound = "inbound.xls";
$fisierOutbound = "outbound.xls";

callsInbound();

function callsInbound() {

        global $fisierInbound;
        global $current;

        global $con;

        $identify = PHPExcel_IOFactory::identify('daily/' . $fisierInbound);
        $objReader = PHPExcel_IOFactory::createReader($identify);
        $objReader->setReadDataOnly(true);
        $objPHPExcel = $objReader->load('daily/' . $fisierInbound);
        $worksheet = $objPHPExcel->setActiveSheetIndex(0);

        $query = mysqli_query($con, "SELECT * FROM users WHERE tip_user='agent' AND NOT (departament='online')");

        while($usr = mysqli_fetch_array($query)) {
                        $data[] = $usr;
        }

        $worksheetTitle     = $worksheet->getTitle();
        $highestRow         = $worksheet->getHighestRow(); // e.g. 10
        $highestColumn      = $worksheet->getHighestColumn(); // e.g 'F'
        $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
        $dataCalls = $worksheet->getCellByColumnAndRow(2, 2)->getValue();
        $dataSubstr = substr($dataCalls, 53);
        echo $dataSubstr;
        foreach ($data as $db) {

            for ($row = 6; $row <= $highestRow; ++ $row) {

                $marca      = $worksheet->getCellByColumnAndRow(3, $row)->getValue();
                $nr         = $worksheet->getCellByColumnAndRow(4, $row)->getValue();

                if($db['marca'] == $marca) {
                    mysqli_query($con, "INSERT INTO dailycalls(data, nr, departament, oras, tip, id_user)
                                        VALUES('$dataSubstr', '$nr', '" . $db['departament'] . "', '" . $db['oras'] . "', 'inbound', '" . $db['id'] . "')");
                }
            }
        }
}

The thing is that I get "No data receive Error code: ERR_EMPTY_RESPONSE" (chrome) from processCalls, so the ajax request fails. As it fails I think it is running the file more than once, because I get more results than I need in the db. If I run the file manually I get the results I need. ( side note: the processCalls.php's query runs despite the error I get ). I hope that makes sense.

Thanks!

Check if the click function is getting binded more than once.

If the click function is binded more than once the function will be called multiple times.

$("#applyCalls").off('click', callServer).on('click', callServer);

var callServer = function(){
    $.get("admin/processCalls.php");
};
