Auto update price fields of Gross and Net on product creation page

Hi,

after unsuccessful searching of javascript/jquery function that updates automatically the prices in input fields (both for Gross and Net prices), i wrote a custom function which you should integrate into your administration template (index.php) to make it work.

It's the same functionality which were on older version of VirtueMart component (1.x)

So here you go, copy and paste it just before the end of the <body> tag in your main admin template file (index.php):

Code Select

	
<script type="text/javascript">
	jQuery(function($){
		
		var priceBase = $('input[name="mprices[product_price][]"]', '#productPriceBody');
		var priceFinal = $('input[name="mprices[salesPrice][]"]', '#productPriceBody');
		var priceDiff = parseFloat(priceFinal.val()) - parseFloat(priceBase.val());
		var priceTaxReal = priceDiff / priceBase.val();
		var priceTax = Math.round(priceTaxReal * 100) / 100
		
		priceBase.keyup(function(){
			updateGross();
		});
		priceFinal.keyup(function(){
			updateNet();
		});
		
		// Return PLACES digit X after the comma
		function doRound(x, places) {
			return Math.round(x * Math.pow(10, places)) / Math.pow(10, places);
		}
		
		function updateGross(){
			var grossValue = priceBase.val();
			if( grossValue != '' ){
				if(priceTax > 0){
					grossValue = grossValue * (priceTax + 1);
					priceFinal.val(doRound(grossValue, 5));
				}
			}
		}
		
		function updateNet(){
			var netValue = priceFinal.val();
			if( netValue != '' ){
				if(priceTax > 0){
					netValue = netValue / (priceTax + 1);
					priceBase.val(doRound(netValue, 5));
				}
			}
		}
		
	});
</script>
