Most of the users of my script are hosted on a server that inserts a text ad at the end of each page. Unfortunately, this code is appearing in my script's AJAX responses as well. The unwanted content is an HTML comment followed by a link to their signup page. I need help in figuring out how to remove this comment and link from the end of my AJAX responses.
Usually, these scripts search for text/html content and directly insert the code into the stream. Have you experimented with changing the content type to something different like text/json, text/javascript, text/plain to see if it prevents the injection?
If you're looking to clean up some messy data using regular expressions, here's a tip. Crafting the perfect regex may take some practice, but it can save you time in the long run.
var rawData = "Here is the information you need. <strong>Nothing more</strong> <!-- sneaky comments --> <a href='example.com'>Don't be fooled!</a>";
var cleanedData = rawData.replace("/\s+?<!--.*>$/gi", "");
An easy way to handle incoming data with custom separators is to append a specific string ("separator!") at the end and split the text based on that delimiter.
var cleanedData = rawData.split("separator!")[0];
This method ensures that only the intended data before the separator is processed, eliminating any unwanted additions.
When dealing with hand-generated XML, it is common to encounter invalid formatting. Many consumers attempt to remedy the issue by using manual regex corrections, but this method is fundamentally flawed. The key is to address the problem at its root source - the faulty host.
