javascript variable after a call to the server

[dannynjust]

i just begin to learn javascript . so this question may seems silly . but it happens . so this is the question:
i made application that user can get data from the server , each time the user click on a button the application retrieve new data that is different from the last one . can i store the data that each time retrieved from the server in a javascript array so next call to the server , i just push the new data into the array. is that possible?
from what i see it seem the browser just wept out all the variable after each call to the server.
someone can help me ? thanks in advance .
