How can I check with JQuery, if a certain word is typed in the Browser?

Ok, I have found this great plugin in order to capture and execute hot key commands for jQuery.
http://plugins.jquery.com/project/hotkeys

My question before I get too involved in this is that I noticed the “+” between the keys. I was looking for something that would capture what the user enters after typing a string.

the goal is to call a function that will show quick data on a “job” that is stored in the database. For example: (all of this is key stroked not holding down the combination)

If the user types this combination: c v l

then a function is called to listen for the next command. The user then types: 1 2 3

this would then fire another function to find job: 123 from the database.

Basically I am looking for an idea on how this might be possible. If anyone has any idea or if I need to provide more details please let me know. Thanks!

Answer 1

I would simple add a keyup function and look at the keys that being pressed. So something like this pseudocode:

my_array_interesting_keys = [c,v,l]
current_sequence = null

window.onKeyup:
   if(key in my_array_interesting_keys) {
      current_sequence[] = key
   } else {
      current_sequence = null 
      // abort current sequence
   }

   if(current_sequence.length == 3) {
       if(implode('', current_sequence) == implode('', my_array_interesting_keys)) {
          // wait for number to be entered now
       } else {
          current_sequence = null
       }
   }

Obviously this would need to be refined and converted into actual JS.
