Remarks

In for the events preOnclickJS and postOnclickJS you cannot access application model or APIs, as these functions are executed in browser whereas the remaining JavaScript modules are executed in server. For these events you can access browser objects ( window, document etc.) to change UI or perform some validation before server event. If the event preOnclickJS returns true, only then the request is sent to server for subsequent action.

You have to specify the modules to be loaded in browser using import JavaScript tab, only then these files get included in html script tag otherwise you will not be able to access the objects defined in those modules.

Example

//The below function is the callback function for postOnclickJS event of Horizontal Image strip.
function postOnclickJSCalBck(hIS)
{
	 //Write your logic here.
}
					
//Creating Horizontal Image strip with postOnclickJS:postOnclickJSCalBck
var hISBasic={id:"hIS", 
	skin:"hISkn", 
	focusSkin:"hISknFocus", 
	isVisible:true, 
	selectedIndex:1,
	imageWhileDownloading:"img.png", 
	imageWhenFailed:"img3.png", 
	spaceBetweenImages:20, 
	data:[[{"imagekey":"image1.png"}, {"imagekey":"image2.png"},"imagekey"]], 
	viewType:constants.HORIZONTAL_IMAGESTRIP_VIEW_TYPE_COVERFLOW, 
	showArrows:true
	showScrollbars:true};

var hISLayout={padding:[5,5,5,5], 
	margin:[5,5,5,5], 
	paddingInPixel:true, 
	marginInPixel:true, 
	referenceWidth:100,
