Question

I am sending an ajax call via the following:

var response = sendViaAjax(str,'Session/delete_From_Session_AJAX.php') ;

    alert('response:|'+response+'|') ;

    if(response == 'complete') {//returns complete if the table was not to be rewritten
        el = this ;
        while(el.tagName !== 'TR'){
            el = el.parentNode ;
            alert(el.tagName) ;
        }
        removeChildren(el) ;
        removeElement(el) ;
    }else if(response!= 'complete') {
        alert(response+' is not equal to complete') ;
        parseHTMLStr(response,window.cur_tbl,1,0,0) ;       
    }

The relevant code from delete_Session… is

if( isset($_POST['REWRITE']) ) {
    include("return_Tabular_Data.php") ;
}else{
    echo 'complete' ;
}

The alert I am getting from the formatted string is:

complete
         is not equal to complete

Something must be added but I cannot find where. I use this function extensively and have never had a similar issue.

The only place I modify the response in sendViaAjax is

var RESPONSE = xmlhttp.responseText ;
RESPONSE = RESPONSE.replace(/^\s+/, '');
return RESPONSE ;

Do you have whitespace after your closing ?> tag on the server-side?

Ideally, when using AJAX you want to exit specifically when you want output to end. Or you can just not put ?>, since it’s optional at the end of the file.
