Question 170

A developer applies this approach: Use an appropriate onLoad Client Script to set a client-side message. What platform behavior or outcome should be expected for the stated design?

  1. onChange handles an edited field while load-time guards prevent unintended initialization effects.
  2. Client-side submission checks improve usability but cannot be the sole source of data validation.
  3. Client UI controls modify presentation and should not be treated as record security.
  4. An onLoad script executes when the form loads in supported clients and can guide the user.

Explanation

Correct Answer

D:

The expected result for On-load client guidance is: An onLoad script executes when the form loads in supported clients and can guide the user.

Incorrect Answers

A:

This describes On-change dependent prompt and its associated action, Use an onChange Client Script with a guard for loading and the relevant field, rather than the consequence of the stated approach.

B:

This describes Submission confirmation logic and its associated action, Use an appropriate onSubmit Client Script for immediate feedback and enforce the rule on the server too, rather than the consequence of the stated approach.

C:

This describes g_form field visibility and its associated action, Use a supported g_form API in client logic or a UI Policy to control field visibility, rather than the consequence of the stated approach.

Question 171

A browser form should show an informational help message as soon as the request form opens. A teammate suggests a different change: Use an onChange Client Script with a guard for loading and the relevant field. That change does not resolve the actual requirement. Which correction is most appropriate?

  1. Use an appropriate onLoad Client Script to set a client-side message
  2. Use an onChange Client Script with a guard for loading and the relevant field
  3. Use an appropriate onSubmit Client Script for immediate feedback and enforce the rule on the server too
  4. Use a supported g_form API in client logic or a UI Policy to control field visibility

Explanation

Correct Answer

A:

Use the indicated corrective approach. An onLoad script executes when the form loads in supported clients and can guide the user. This meets the specific requirement for On-load client guidance.

Incorrect Answers

B:

Not the appropriate correction: Use an onChange Client Script with a guard for loading and the relevant field is relevant to On-change dependent prompt. onChange handles an edited field while load-time guards prevent unintended initialization effects.

C:

Not the appropriate correction: Use an appropriate onSubmit Client Script for immediate feedback and enforce the rule on the server too is relevant to Submission confirmation logic. Client-side submission checks improve usability but cannot be the sole source of data validation.

D:

Not the appropriate correction: Use a supported g_form API in client logic or a UI Policy to control field visibility is relevant to g_form field visibility. Client UI controls modify presentation and should not be treated as record security.

Question 172

A developer proposes this approach: Use an appropriate onLoad Client Script to set a client-side message. Which business requirement is the strongest reason to choose it?

  1. When the customer category changes on a form, the description help text should update immediately.
  2. A browser form should show an informational help message as soon as the request form opens.
  3. A custom form should block accidental submission when a required business acknowledgement is missing.
  4. When a request type is set to Internal, a justification field should be hidden on that desktop form.

Explanation

Correct Answer

B:

This business need directly motivates Use an appropriate onLoad Client Script to set a client-side message; An onLoad script executes when the form loads in supported clients and can guide the user.

Incorrect Answers

A:

The described situation is better addressed by Use an onChange Client Script with a guard for loading and the relevant field. onChange handles an edited field while load-time guards prevent unintended initialization effects.

C:

The described situation is better addressed by Use an appropriate onSubmit Client Script for immediate feedback and enforce the rule on the server too. Client-side submission checks improve usability but cannot be the sole source of data validation.

D:

The described situation is better addressed by Use a supported g_form API in client logic or a UI Policy to control field visibility. Client UI controls modify presentation and should not be treated as record security.

Question 173

When the customer category changes on a form, the description help text should update immediately. Which application design or configuration action best addresses this requirement on the ServiceNow platform?

  1. Use an appropriate onSubmit Client Script for immediate feedback and enforce the rule on the server too
  2. Use a supported g_form API in client logic or a UI Policy to control field visibility
  3. Check script type, target table and field, then debug in the browser with a reproducible test
  4. Use an onChange Client Script with a guard for loading and the relevant field

Explanation

Correct Answer

D:

Correct for On-change dependent prompt: onChange handles an edited field while load-time guards prevent unintended initialization effects.

Incorrect Answers

A:

That action instead addresses Submission confirmation logic. Client-side submission checks improve usability but cannot be the sole source of data validation. It does not directly fulfill the stated On-change dependent prompt requirement.

B:

That action instead addresses g_form field visibility. Client UI controls modify presentation and should not be treated as record security. It does not directly fulfill the stated On-change dependent prompt requirement.

C:

That action instead addresses Debug client execution. Client execution failures require inspecting browser-side conditions rather than server logs alone. It does not directly fulfill the stated On-change dependent prompt requirement.

Question 174

  3. Client UI controls modify presentation and should not be treated as record security.

  4. A desktop field script appears not to run after a priority change.

Explanation

Correct Answer

C:

This business need directly motivates Use an onChange Client Script with a guard for loading and the relevant field; onChange handles an edited field while load-time guards prevent unintended initialization effects.

Question 177

A custom form should block accidental submission when a required business acknowledgement is missing. Which application design or configuration action best addresses this requirement on the ServiceNow platform?

  1. Use an appropriate onSubmit Client Script for immediate feedback and enforce the rule on the server too
  2. Use a supported g_form API in client logic or a UI Policy to control field visibility
  3. Check script type, target table and field, then debug in the browser with a reproducible test

Explanation

Correct Answer

A:

Incorrect Answers

B:

That action instead addresses g_form field visibility. Client UI controls modify presentation and should not be treated as record security. It does not directly fulfill the stated Submission confirmation logic requirement.

C:

That action instead addresses Debug client execution. Client execution failures require inspecting browser-side conditions rather than server logs alone. It does not directly fulfill the stated Submission confirmation logic requirement.

D:

That action instead addresses Client to server lookup. A supported asynchronous client-server call keeps privileged data access on the server. It does not directly fulfill the stated Submission confirmation logic requirement.
