judge according to the answer


intercept the value of the key corresponding to the answer, intercept the last element (a ~ b ~ c ~ d) and convert it to uppercase. D) compared with the value value of rights field, true got it right. False got it wrong.


change the data format ~ convenient and convenient ~


A:<input type="radio" name="q1" value="A" title=""><br>
B:<input type="radio" name="q1" value="B" title=""><br>
C:<input type="radio" name="q1" value="C" title=""><br>
D:<input type="radio" name="q1" value="D" title=""><br>
<script>
    window.onload = function (ev) {
        var result = [];
        var radio = document.querySelectorAll('input[type=radio]');
        for (var i = 0; i < radio.length; iPP) {
            radio[i].onchange = function (ev2) {
                console.log(this.value);
                console.log(this.name);
                var request = {key: '', value: ''};
                request.key = this.name;
                request.value = this.value;
                console.log(request);
            }
        }
    };
</script>

you can get ABCD,. Then judge ABCD, ah, it can be more options, or it can be indeterminate choice
in fact, this question has many extensions
the original question can be ABCD, and then randomly change the bit BCDA (but displayed as ABCD, etc.), and then get the choice to judge
in order to simplify the judgment, you can first sort the answers and then compare them with the answer string.


  

I think the easiest way is to write value in the tag and compare it with the answer
