SDAPI Variables, Objects and Object Members 2.0

The Script Debugger API (SDAPI) enables you to interact with halted script threads. When a script thread is halted, you can fetch the list of objects in the context of a script thread and call stack frame. You can also fetch objects inside an object.

To access objects and object members, you use the variables and members actions and you specify a thread identifier and call stack frame index. When requesting members, you can optionally include the object_path query parameter. If you do not use the object_path query parameter, the Script Debugger will return all objects in the context of the specified thread and frame index.

When you specify an object_path query parameter, the value of the parameter is a dot-delimited string representing a path. For exampole, if the query parameter is basket the Script Debugger returns the members of the basket object. If the query parameter is basket.productLineItems , the Script Debugger returns all members of the productLineItems member of the basket object.

The response from the members action is a collection of JSON objects containing four properties:
  • name: the name of the object.
  • parent: the parent of the object.
  • type: the type of the object.
  • value: the value of the object. The value is obtained by calling toString() on the object.
When you an object represents a collection, the name attribute is an index representation of the member inside the collection. For example, "name":"[0]" represents the first element in the collection.

By default, the Script Debugger will return up to 200 objects for the members action and the result set starts with element 200 . If the object path has more than 200 elements, you can use the start and count query paramters to control the returned objects.

When requesting variables, the response is a collection of JSON objects containing four properties:
  • name: the name of the object.
  • parent: the parent of the object.
  • type: the type of the object.
  • value: the value of the object. The value is obtained by calling toString() on the object.
  • scope: the scope of the variable, where the value is one of local , closure or global .

In the vast majority of cases, you do not want to interact with a “running” script thread, because there is no guarantee that the thread will be alive when your request is processed.
