解决方案

Hi,

We cannot use JavaScript to access variables data from the workflow Initiation form. SharePoint JavaScript Client Object Model does not provide function to access workflow variable.

The data is stored in an SPWorkflowActivationProperties object. Any information passed to the form is formatted as the XML string. To access these custom properties, we need to write C# code that parses the XML string.

Here is an article about how to access Association and Initiation Form Data in a Workflow in SharePoint Server. Though the article is for SharePoint 2010, it still has good information:
