Question

Is there a way for a button to automatically delete its corresponding index in an array upon being clicked?

I am currently developing a multiple choice quiz where users can input their own questions and answers to create a quiz. I am facing an issue with allowing users to delete questions stored in the question bank.

Here is what I have tried so far:

bodyText = bodyText + '<button onClick="questionBank.splice(1,1)">Delete me</button>';

I am struggling to make it so that when the user clicks on the button, it deletes the specific element in the array to which the button is attached. I realize that the splice (1,1) function is only deleting the first element in the array, not the element associated with the button.

Answer №1

The functionality of your question bank system is somewhat uncertain, and this lack of clarity could potentially impact the optimal solution. However, it is essential to ensure that, at the very least, the question's ID is passed into the delete function. Your HTML code might resemble this:

bodyText = bodyText + '<button onClick="deleteQuestion(12)">Delete me</button>';

Subsequently, you should have a function that manages the deletion process:

function deleteQuestion(id) {
    questionBank.splice(id,1);
}

When constructing the HTML for the page, incorporating the ID into the button click should be a relatively straightforward task.
