Question

I have a js script which has only one variable, but that variable holds a 20 MB String. I need to load that script so i can transform that String Into an XML object, so i can emulate offline search on a website.

I need ideas on how to accomplish this.
First, I must probably wait the js script to be loaded. I don’t know how to do that, i tried with jQuery and i did not succeed.

Answer 1

OPTION 1:

• break the 20 MB into 1 MB (or even 512 KB) chunks.
• enumerate those chunks — i.e. give them numbers 1,2,3 — to identify their order
• then load them in parallel ajax requests — may be 3-4 parallel requests (or more?)
• once all are downloaded to the browser — join’em — and you’ve got your 20 MB text ready

OPTION 2:

use flash — you can do better ajax with it (if i am not wrong) and it will also tell you the loading status

OPTION 3:

in HTML 5 browsers you might use WebSockets. and gracefully degrade in older clients
