Answer 1

就是将表格上的评份汇总

var a1 = document.getElementById("a1"); //获取ID名为a1元素对象
var a1 = a1.innerText.toString().replace(/(^\s*)|(\s*$)/g, "");//将a1元素中的文本转换成字符串类似，并清除前后空格
a1 = a1.replace(/[^\d]/g, ""); //只保留数值信息
var dangerpatient = Number(a1) + Number(a2) + Number(a3) + Number(a4) + Number(a5) + Number(a6) + Number(a7) + Number(a8) + Number(a9) + Number(a10) + Number(a11) + "分";//将所有变量转换成数值类型并相加，赋值给dangerpatient
z1.innerText = dangerpatient;//显示结果
