SNOW-CAD User Interface Development Practice Question

Correct answer & explanation

Correct options A and B. A: onChange fires when a field value changes. B: onSubmit fires when the form is submitted. C: onLoad is actually a separate type but the name 'onLoad' is correct; the option says 'onLoad' which is valid but we have to choose two. Actually careful: options are A: onChange, B: onSubmit, C: onLoad, D: onDelete, E: onUpdate. The valid types are onChange, onSubmit, onLoad, and onCellEdit. So A and B are valid; C is also valid but we need exactly two correct. The stem says 'Which TWO' but if three are valid, we need to ensure only two are listed as correct. In this case, we'll make A and B correct, and C incorrect (maybe 'onLoad' is not a type? Actually it is. But we can say 'onLoad' is not a value for the 'Type' field? Wait, client script types: onChange, onSubmit, onLoad, onCellEdit. So onLoad is valid. To make only two correct, we can change the options: e.g., A: onChange (correct), B: onSubmit (correct), C: onLoad (incorrect?) No, onLoad is correct. Let's adjust: replace option C with something else like 'onClick' which is not a standard type. So we'll set: A: onChange (correct), B: onSubmit (correct), C: onClick (incorrect), D: onDelete (incorrect), E: onUpdate (incorrect). That works.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
