Try This define a function call "function slider" and for that function pass class name or id
function slider(elemname,minIt,maxIt) {
// store the slider in a local variable
var $window = $(window),
flexslider2 , flexslider;
// tiny helper function to add breakpoints
function getGridSize() {
return (window.innerWidth < 600) ? 1 :
(window.innerWidth < 1220) ? minIt : maxIt;
}
$(function() {
SyntaxHighlighter.all();
});
$(elemname).flexslider({
animation: "slide",
animationSpeed: 400,
animationLoop: false,
itemWidth: 270,
itemMargin: 20,
minItems: getGridSize(), // use function to pull in initial value
maxItems: getGridSize(), // use function to pull in initial value
start: function(slider2){
flexslider2 = slider2;
}
});
// check grid size on resize event
$window.resize(function() {
var gridSize = getGridSize();
flexslider2.vars.minItems = gridSize;
flexslider2.vars.maxItems = gridSize;
});
}
and call this function inside document.ready function i.e.
slider("<Your class name or id name>");
in your case it should be
slider("#home-slider-four",3,4); and slider("#home-slider-five",4,5);
