Question

Fellow coders, I have asked this question before but did not get a conclusive answer to it. The question is: how much data can i safely return from and ajax post call before i run into some limitation somewhere?

The scenarios are basically like this: front-end makes an ajax call to a php controller/model. the controller returns a bunch or rows from the database or returns some html representing some report which will be stored in a js string var to be displayed later.

I see two limitations here: the size of the data returned through the ajax call and max size the js var can hold.

Anyone knows what the limits are?

thanks

Answer 1

See this answer: Javascript maximum size for types?

In short, unless the browser specified otherwise, variable sizes are not subject to a restriction. As for Ajax: There’s no limit, unless defined server-side (such as this one).
