Basic use of the using the google analytics event feature supplying a renamed google analytics function The code for the google analytics is:
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','_gaNixLabel');
_gaNixLabel('create', 'UA-12345678-9', 'auto');
$('#test1').nutritionLabel({
showLegacyVersion : false,
allowGoogleAnalyticsEventLog : true,
gooleAnalyticsFunctionName : '_gaNixLabel'
});
This is an example where the user function "alertMe" is triggered when the quantity value is changed. The plugin calls the function "alertMe" with 3 parameters 1. kind - textbox / up arrow / down arrow 2. previous value 3. new value The code of "alertMe" is:
function alertMe(kindValue, OldValue, NewValue){
console.log(
'kindValue => ' + kindValue + "\n" +
'OldValue => ' + OldValue + "\n" +
'NewValue => ' + NewValue
);
}
$('#test2').nutritionLabel({
allowTriggerOfUserFunctionOnQuantityChange : true,
userFunctionNameOnQuantityChange : 'alertMe',
showLegacyVersion : false
});
