javascript - How to create new slide item in owl carousel dynamically

问题描述

I want to create owl item slides dynamically on the basis of conditions. Such as 

if(i=1 && i<=4)
{

//generate new item slide (owl carousel)
}
else if(i>=4 && i<=8)
{

//Generate second slide
}

I am creating the slide item manually, i want to make them dynamically on the basis of condition in jquery. Suppose the first condition met, create new slide item dynamically, if second condition met, create new slide dynamically. I am new at jquery

Ps:- slide should create dynamically with the help of jquery .

Here is slider code

To use Owl Carousel, you’ll need to make sure both the Owl and jQuery 1.7 or higher scripts are included.You don't need any special markup. All you need is to wrap your divs(owl works with any type element) inside the container element . Class "owl-carousel" is mandatory to apply proper styles that come from owl.carousel.css file.
