類似這種沒有完成動作的計算(例如:點擊提交問卷,就是一種完成動作,可以在這時候去計算總分),你需要在每一次操作的時候計算總分,如果有使用Vue,用計算屬性就很漂亮了~

所以上面的點擊事件需要更改:(程式碼還沒有驗證,但思路是那樣)

//记分设置
$(document).ready(function(){
    var result = 0;
    $('.a').click(function(){
        result = result + 1;
        console.log(result);
    });
    $('.b').click(function(){
        result = result + 2;
        console.log(result);
    });
    $('.c').click(function(){
        result = result + 3;
        console.log(result);
    });
    $('.d').click(function(){
        result = result + 4;
        console.log(result);
    });
});

// 修改为:
$(document).ready(function(){
    $(".choice input[type='radio']").on('click', count);
});

var result = 0;
function count() {
    var _result = 0;
    for (var i = 1; i <= 10; i++) {
        var option = $(".choice input[name='"+i+"']:checked"); // 选中的选项
        if (option.attr("class")) {
            var score = 0;
            switch(option.attr("class")) {
                case "a":
                    score = 1;
                    break;
                case "b":
                    score = 2;
                    break;
                case "c":
                    score = 3;
                    break;
                case "d":
                    score = 4;
                    break;
                default:
                    break;
            }
            _result += score;
        }
    }
}
阿神

點擊的時候需要加標識符判斷是否更改了選項- -不然做題的人在abcd間不停切換你的result也會累加,就亂了,最後輸出結果肯定是根據各個分數段的- -用switch或一堆eles if都隨你了
