如何将JSON数组从文本/ JavaScript块传递到精确目标/ Salesforce营销云中的runat = server块？

Question

I've got a page with two <script> blocks on it, one running locally, one running on the ExactTarget server:

<script type="text/javascript">
var results = localStorage.getItem('results');
var results = JSON.parse(results);
</script>

<script runat=server>
Platform.Load("Core","1");
Write(Stringify(results)); //this returns a 'null' value
var campaignsupdate = DataExtension.Init("0DB9904F-CE05-45E7-8052-    7C6935B4B012");
for(var i=0; i < results.length; i++) {
var rowid = results[i]["ROWID"];
var title = results[i]["title"];
campaignsupdate.Rows.Update({title: title},["ROWID"], [rowid]); 
}
</script>

At the moment, calling 'results' in the 'runat=server' block returns a null value. How do I access the 'results' array in the 'runat=server' block?

Answer 1

You can't. As the Server Side Java Script runs on the server :), it's executed prior to the javascript which is executed on the client machine, so the var 'results' does not exists when you access to it in the SSJS block. As far as I know SSJS can't communicate with javascript so you can't use javascript libraries or code written in a javascript block. As an alternative, you can pass a value in the GET/POST request and get it in SSJS.
