类似这种没有完成动作的计算(例如:点击提交问卷,就是一种完成动作,可以在这时候去计算总分),你需要在每一次操作的时候计算总分,如果有使用Vue,用计算属性就很漂亮了~

所以上面的点击事件需要更改:(代码还没有验证,但思路是那样)

//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

点击的时候需要加标识符判断是否更改了选项- -不然做题的人在abcd间不停切换你的result也会累加,就乱了,最后输出结果肯定是根据各个分数段的- -用switch或者一堆eles if都随你了
