each option depends on whether you click to render the is-selected class

at the same time, the is-correct class is-error class renders to the corresponding element based on the correct answer and the wrong answer

is-correct appears green and elements with is-selected is-error classes show red

Click the option to render the is-selected class, click submit, and then render the is-correct is-error class


each of your options is rendered in a for loop, so the option for the correct answer is also known.

/**/
<div v-for="(item, index) in question">
    <div :class="bindClass" @click="clickItem(index)"></div>
</div>

data() {
    return {
        question: [...],
        bindClass: '' //
    }
}
/**/
clickItem(index) {
    if(question[index]===){
        bindClass = correctClass //
    }else {
        bindClass = errorClass /
    }
}

but I don't know what the format of the data returned by you in a question looks like. Can you roughly see if this idea is feasible?


give each option several states. 0 is not selected, 1 is selected without judging whether it is the answer, 2 is judged to be the wrong answer, 3 is judged to be the correct answer
