An Adobe Commerce developer wants to apply a knockout binding to a

to run a function, onClick(), when it's clicked. Which two solutions would the developer use to achieve this? (Choose two.)

<x/div>

Show Suggested Answer

Suggested Answer: A, C

To apply a knockout binding to a

to run a function, onClick(), when it's clicked, the developer can use either of the following solutions:

: This solution will use the click binding to execute the onClick() function as an expression when the

is clicked. The function will be called with the current binding context as the first parameter and the event object as the second parameter.

: This solution will use the click binding to execute the onClick function as a reference when the

is clicked. The function will be called with the current binding context as the first parameter and the event object as the second parameter.

The following solutions are not valid and will not work:

: This solution will use the virtual element syntax to apply the click binding, but it will pass a string literal instead of a function expression or reference. This will cause an error, as the click binding expects a function value.

: This solution will use a custom attribute instead of a data-bind attribute to apply the click binding. This is not supported by knockout and will not have any effect.

I think option D is clearly incorrect because the syntax is incorrect. I would go with options A and C as well for applying the knockout binding to run a function onClick().

I'm not sure about option B. It looks a bit confusing with the comments around the 'ko' binding. I would definitely go with options A and C.

I agree with Argelia. Option A and Option C seem like the most logical choices for applying a knockout binding to run a function onClick().

I think option A and option C are the correct solutions because they involve using the 'click' binding to call the 'onClick' function.

So, both options A and C involve using data-bind and click binding to execute the onClick() function when the

is clicked.

I believe option C is correct because it also uses the data-bind attribute and the click binding to trigger the function onClick.

Option A uses the data-bind attribute and the click binding to run the function onClick(). It seems like the most logical choice to me.

I'm not sure about option A. Can you explain why you think it's correct?

Agreed, Eliz. A is definitely not the right answer. The syntax should be just the function name, not the function call.

Haha, this question is a bit tricky. I was about to choose A, but then I realized that the 'onClick()' syntax is not correct. It should just be 'onClick'.
