Custom script for Greasemonkey that modifies a parameter within the URL

While using Google Analytics, I have noticed that some pages display a variable in the URL with a default value of 10. The format usually looks like this:
...&trows=10&...
Is there a method to alter this to trows=100 in order to change the default number of displayed rows to 100? Thank you

Answer №1

if (/[\?&]trows=10[^\d]/i.test(document.location.href)) 
    document.location.replace(document.location.href.replace("trows=10","trows=100"));

Make sure to utilize document.location.replace() in order to maintain functionality of the browser's back button.

Answer №2

if (/trows=10(?!\d)/.test(location.href)) 
    location.href=location.href.replace("trows=10","trows=100");

Update: To revert back to the trows=10 page using the browser's back button, it is recommended to use the .assign method in place of .replace. However, if you prefer trows=100 as the default setting, this step may not be necessary.

location.assign(location.href.replace("trows=10","trows=100"));

Answer №3

Absolutely! It's possible to alter links on the page, refresh the page with a modified parameter when an incorrect one is present in the URL, or even do both at the same time. Utilizing XPath can be incredibly handy for locating links if needed, but it's not always essential. Additionally, you have the option to adjust window.location.search for the latter scenario.
