Custom errors, extending Error — JavaScript

https://javascript.info/custom-errors

javascript — Error message: Object not found! on calling PHP script in AJAX

I have created a very basic page that retrieves all contacts from my contact MySQL table using AJAX:

html xmlns="http://www.w3.org/1999/xhtml">     
 
  
 
   Copy code

PrintContacts.js

var xmlHttp; function printContacts() < xmlHttp = new XMLHttpRequest(); var url = "PHP/getAllContacts.php"; // Workaround for page caching url = url + "&sid=" + Math.round(Math.random() * 1000000000); // Commenting the line above removes my issue but I do need this for caching. // Manage XmlHttpObject state change xmlHttp.onreadystatechange = stateChanged; xmlHttp.open("POST", url, true); xmlHttp.send(null); >function stateChanged() < // Check if the XmlHttp request is complete if (xmlHttp.readyState == 4) < // Set the XmlHttp response in the div contacts document.getElementById("contacts").innerHTML = xmlHttp.responseText; >> Copy code

getAllContacts.php

"; // Table headers echo "Name"; // Print all contacts while($row = mysql_fetch_array($result)) < echo ""; echo "" . $row['DisplayName'] . ""; echo ""; > echo ""; mysql_close($dbconnection); ?> Copy code

Opening the getAllContacts.php directly returns the appropriate table with the data, however, opening index.php, results in an error:

Object not found!

The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated. Please inform the author of that page about the error.
If you think this is a server error, please contact the webmaster.

Error 404

localhost
12/08/2010 2:47:27 PM
Apache/2.2.14 (Win32) DAV/2 mod_ssl/2.2.14 OpenSSL/0.9.8l mod_autoindex_color PHP/5.3.1 mod_apreq2-20090110/2.7.1 mod_perl/2.0.4 Perl/v5.10.1

I found out that adding &SID= is the root of the issue. This is happening in the PrintContacts.js file. Removing that loads the page appropriately. But I DO need that in order to workaround the caching. Do you know how to resolve this?

Solution

Answer

Solution:

When using AJAX, the url should be linked based on the browser’s current location, not the location of the javascript file.

Change the url in printContacts() to just «PHP/getAllContacts.php».

EDIT: Ok. I figured it out! In the PrintContacts.js, you need to change this line

url = url + "&sid button-copy" onclick="CopyToClipboard('code-6')" >Copy code

url = url + "?sid button-copy" onclick="CopyToClipboard('code-7')" >Copy code

Note the question mark in there. Having the & made it look for a file named getAllContacts.php&192837, not a file named getAllContacts.php.

Answer

Solution:

I am going to suggest only one thing

can you please use the full url instead

 var url = "http://www.blahblah.com/PHP/getAllContacts.php"; Copy code

Answer

Solution:

My guess is that your error lies here:

var url = "../PHP/getAllContacts.php"; Copy code

Replace the url with either the absolute url, or something relative to the domain instead of relative to the JS file.
