call normal javascript using angualrjs

Question

I'm trying to include legacy javascript code for affiliate tracking into an angularjs app

<script type="text/javascript">
        //<![CDATA[ 

        /*** Do not change ***/
        var AWIN = {};
        AWIN.Tracking = {};
        AWIN.Tracking.Sale = {};

        /*** Set your transaction parameters ***/
        AWIN.Tracking.Sale.amount = '{{order_total}}';
        AWIN.Tracking.Sale.orderRef = '{(order_id}}';
        AWIN.Tracking.Sale.parts = '{{cats}}';
        AWIN.Tracking.Sale.voucher = '';
        AWIN.Tracking.Sale.currency = 'GBP';
        AWIN.Tracking.Sale.test = '0';
        AWIN.Tracking.Sale.channel = 'aw';
        //]]>
    </script>

I need to call the above code (filling in the place holders with angualr vars) and then call this:

    <script src="https://www.dwin1.com/xxxx.js" type="text/javascript" defer="defer"></script>

What is the best way to do this? I've tried placing the code into an Angular function with no success I've also tried passing the vars down into $window and trying to insert them into the CDATA at my end with no success. Any ideas?

I should add this code sits in a HTML page wrapped in an angualrjs controller

Answer 1

what you are trying is not possible directly with angularjs. you need to do something like below

//Note: this is a new JS file included in your main html

(function() {
    "use strict";

    window.AWIN = {};

    window.populateAwin = function(args) {
        //<![CDATA[ 

        /*** Do not change ***/
        AWIN.Tracking = {};
        AWIN.Tracking.Sale = {};

        /*** Set your transaction parameters ***/
        AWIN.Tracking.Sale.amount = args.order_total;
        AWIN.Tracking.Sale.orderRef = args.order_id;
        AWIN.Tracking.Sale.parts = args.cats;
        AWIN.Tracking.Sale.voucher = '';
        AWIN.Tracking.Sale.currency = 'GBP';
        AWIN.Tracking.Sale.test = '0';
        AWIN.Tracking.Sale.channel = 'aw';
        //]]>
    }

}());

you then need to call this function from your controller by passing required data as shown below

populateAwin({
   order_total: $scope.order_total,
   order_id: $scope.order_id,
   cats: $scope.cats
});

Once this is done, you can proceed with inclusion of script dynamically as shown below from your controller

var scriptEl = document.createElement("script");
scriptEl.type = "text/javascript";
scriptEl.defer = "defer";
scriptEl.src = "https://www.dwin1.com/xxxx.js";

document.body.appendChild(scriptEl);
