Huge data entry webform performance

I have a webform that allows users to dynamically add 'sections' (which are divs with about 20 data items) to the existing form. The issue as expected is the load times. I have looked at this link here Now I am wondering if there is a way to start the loading x n开发者_如何学JAVAumber of sections after the view port. I don't have the control to change the app. I have been tasked with making it hurt less. I am open to ideas.

My thanks in advance,

Using the method you referred to in the other post...

var x = 10;

for (i = 0; i < x; i++) {
    $('#div' + i).load('content' + i + '.php');
}
