Javascript - issues with replacing text

I am having issues with the replace in my javascript page...I have text that I am editing that is very long....its seems that the replace method doesnt work in large text segments

below is what I want replace...but the variable pre_final_decrypt is a very large character string for encryption..as you can image encryption strings can be very large...thanks


        var v_start_superhero = pre_final_decrypt.replace("!!!!!!!!!!!COMIC_BOOK//////////", "");

No, that code should work "as is". I've set up a little example form on my website: http://schutt.nl/ee/Q_28318638/

Maybe you can try pasting your string in there? There's no submit button, it's not being saved anywhere, just being processed in your browser. Just 'tab' out of any input field after changing it to see the new values in the output fields.

I think the size of the string shouldn't matter. The standard string replace function only replaces the first occurrence so try using a regular expression with the g option (for global):
var v_start_superhero = pre_final_decrypt.replace(new RegExp("!!!!!!!!!!!COMIC_BOOK//////////", "g"), "");

good idea...but when I run it with the regex in there...it craps out.....do I need to import a library for the regex?

heres the encrypted string:

       
        "!!!!!!!!!!!START_COMIC//////////!!!!!!!!!!!STOP_STRIP//////////&END&END*****|.....E.....||.....n.....||.....t.....||.....e.....||.....r.....|"

should be

"Enter"

Hmm ok that's a bit different. If the first part is static you can get rid of that with substring or simple string replace, but if the different parts can be in the string at different positions then I guess here's how I would do this (based on the previous replace):
var v_start_superhero = pre_final_decrypt.replace(new RegExp("!!!!!!!!!!!START_COMIC//////////", "g"), "").replace(new RegExp("!!!!!!!!!!!STOP_STRIP//////////", "g"), "").replace(new RegExp("\&END\&END\\*{5}", "g"), "").replace(new RegExp("(\\|\\.{5}(.)\\.{5}\\|)", "g"), "$2");

Open in new window

The main new thing here is the last replace which takes care of taking the wanted letters out of the repeating patterns of pipe symbols and dots.
