jquery - $.ajax error cannot catch thrown exception from php - 


$.ajax({     type: "post",     url: "functions/add_vendor.php",     data:     {         vendor_info_json : vendor_info_json     },     success:function(result)     {         alert('successfully done.')         location.reload();     },     error: function(jqxhr, textstatus, errorthrown){         alert('error message: '+ textstatus);         alert('http error: '+ errorthrown);     } })

this jquery code i'm working on. , following add_vendor.php file being called.

<?php include_once('../models/vendor_db_manager.php');  $vendor_info_json = $_request["vendor_info_json"]; $db = new vendor_db_manager(); $db->connectto('bby'); try {             //this returns false test code.     if($db->insertdatatotable('mfvendor', $vendor_info_json))     {         $db->disconnect();          header('content-type: application/json');         $data = json_encode($result);         echo $data;     }     else     {         throw new exception("error has been detected.");      } } catch (exception $e) {     header("http/1.1 500 internal server error");             echo "exception occurred: " . $e->getmessage(); } ?>

ok, 'if($db->insertdatatotable('mfvendor', $vendor_info_json))' part false test $.ajax's error handling code. no matter do, error: callback not working if php code throws exception time.

what problems i'm missing here? :(

when server throws internal server error, javascript side it's still success. in success function have check response's status code, , handle accordingly.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
