Is there a Javascript or Ajax function to access cart contents?

-- HikaShop version -- : 3.1.0
-- Joomla version -- : 3.7.2
-- PHP version -- : 7.0

We wanted to hide menus and/or modules based on the content of the shopping cart. A simple approach was to just check the number of items in the cart to see if it were empty and then trigger a jQuery or JS dom to change the object to hidden or visible, etc.

I know we can do this with PHP based on your development docs, but I was hoping I could just write a JS routine and put that into the template via a custom module, etc. to automatically hide or show an item based on the cart status.

Hi,

PHP would be more suitable, Javascript will never be 100% reliable/foolproof, but if that's no problem it's not impossible to do with JS.
If you have a cart module on all your pages for example, you can easily write a few lines of JS code to check if there are products in this cart module or not. There's also a trigger event which you can readily use for when the user adds or removes a product from the cart:

window.Oby.registerAjax(["cart.updated","wishlist.updated"],function(params){
	/*
		params.type : 'cart' or 'wishlist'
		params.id : the cart id. If NaN, it has failed.
		params.el : the dom element where the customer clicked to add the product into the cart
		params.product_id : the product id
		params.resp : object
			ret : the cart id, if 0, it has failed
			product_name : the name of the product
			quantity : the quantity of the product
			image : the url of the product image (50x50)
	*/
	});

Shows you want I didn't know. I was afraid that I would replace the existing ajax functionality...I have read some of the examples using window.Oby, but didn't realize that my function would just be appended to the existing ones!

Thanks!! I realize PHP would be best, but if the module or menu is already on the page, JS is the only way to change it without a page refresh. Its as simple now for me to just change a style selector and append a ".hide" class to an Id to hide/un-hide what I need.

thanks again!

Thanks. I've got a check in PHP with the page with the custom module (script) loads--that way if the user has returned and still has items in the cart, etc. before the ajax update is triggered for a new visit; and then the javascript call added to recheck any time that routine is triggered.
