Ok, I'm a bit of a n00b when it comes to JS (I'm not the greatest programmer) so please be gentle - specially if my questions been asked already somewhere and I'm too stupid to find the right answer. Self deprecation out of the way, let's get to the question.
Problem
There
is a site me and a large group of friends frequently use which doesn't display all the information we may like to know - in this case an airline bookings site and the class of travel.
While the information
is buried in the code of the page, it isn't displayed anywhere to the user.
Using a Greasemonkey script, I'd like to liberate this piece of information and display it in a suitable format.
Here's the psuedocode of what I'm looking to do.
Search dom for specified element
define variables
Find a string of text
If found
Set result to a variable
Write contents to page at a specific location (before a specified div)
If not found
Do nothing
I think I've achieved most of it so far, except for the key bits of:
Searching for the string: The page needs to search for the following piece of text in the page HEAD:
mileageRequest += "&CLASSES=S,S-S,S-S";
The Content I need to extract and store
is between the second equals (=) sign and the last comma ("). The contents of this area can be any letter between A-Z.
I'm not fussed about splitting it up into an array so I could use the elements individually at this stage.
Writing the result to a location: Taking that found piece of text and writing it to another location.
Code so far
This
is what I've come up so far, with bits missing highlighted.
buttons = document.getElementById('buttons');
''Search goes here
var flightClasses = document.createElement("div");
flightClasses.innerHTML = '<div id="flightClasses"> ' +
'<h2>Travel classes</h2>' +
'For the above segments, your flight classes are as follows:' +
'write result here' +
'</div>';
main.parentNode.insertBefore(flightClasses, buttons);
If anyone could help me, or point me in the right direction to finish this off I'd appreciate it.
