SNOW-CAD Practice Question: Application development using ServiceNow Studio
Exhibit
Refer to the exhibit.
```javascript
var MyAjaxProcessor = Class.create();
MyAjaxProcessor.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getData: function() {
var gr = new GlideRecord('incident');
gr.addQuery('active', true);
gr.query();
var result = [];
while(gr.next()) {
result.push(gr.getUniqueValue());
}
return JSON.stringify(result);
}
});
```Refer to the exhibit. A developer created this Script Include for use in a Service Portal widget. When calling the processor from a client script, the developer passes no 'sysparm_name' parameter. What will be the result?
⚠ Common exam trap
Test-takers frequently assume a default method (like getData) runs when no method is specified, but ServiceNow's processor architecture requires an explicit 'sysparm_name' to invoke any method beyond the constructor.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The script will execute the processor's constructor only.
When a Script Include is invoked from a Service Portal widget via a processor, the processor's constructor runs automatically. If no 'sysparm_name' parameter is passed, the processor does not know which method to call, so only the constructor executes. The constructor typically initializes properties but does not return data, resulting in no output.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The script will return an empty array.
Why it's wrong here
Wrong: getData is not called, so no array is returned; the response is empty.
- ✓
The script will execute the processor's constructor only.
Why this is correct
Correct: without sysparm_name, only the constructor runs; no method is executed.
- ✗
The script will throw an error because the method is not allowed.
Why it's wrong here
Wrong: without sysparm_name, the processor does not throw an error; it just doesn't execute any method.
- ✗
The script will run the getData method by default.
Why it's wrong here
Wrong: there is no default method; sysparm_name is required to specify which method to call.
