我正在用 Javascript 构建一个风险计算器程序，为此，我的等级为 1-3，零表示无风险，三表示风险最高。对于每个选项（年龄、性别、BMI、血压、温度、吸烟量等），我将为它们分配一个数字 (0-3)，并使用该数字来确定风险百分比。

示例：年龄：

18-39 = 0 代表风险

40+ = 2 风险

无论用户选择哪个年龄作为他们的年龄都会增加他们的个人百分比。

我怎样才能编写这个程序？

List<StringWithValue> stringList == new ArrayList<StringWithValue>(); 
    int myRisk;
   // no risk  = "0";
    //some risk = "1";
   // risk = "2";
   //abnormal risk = "3";
   var a = "0", b = "1", c = "2", d = "3"


   if(message == "Age") {
      alert("Ages 18 to 39 have a lower risk of cancer" + '\n\n' + 
      "Than for those over 40.");

      StringAge = "18-39";
       StringValue = "a";
       System.out.println("Age" = "a");


       StringAge_2 = "40-80";
       StringValue = "c";
       System.out.println("Age_2" = "c");


   } else if(message =="Sex") {
       alert("Choose your biological gender" + '\n\n' + "Males are more likely to develop" +
            " lung cancer than females.");

   } else if(message == "Systolic Blood Pressure") {
           alert("Low blood pressure is anything below 100" + 'n\n' + "Normal range is 120-130" +
   "High blood pressure is over 135.");

   } else if(message =="Diastolic Blood Pressure") {
       alert("Low blood pressure is anything below 70" + 'n\n' +"Normal range is 80-85" + 
   "High blood pressure is over 90.");

   } else if(message =="Temperature") {
       alert("Below 98.6 degrees Fahrenheit/37 degrees Celsius is unhealthy" + 'n\n' + "Normal range is at exactly 98.6 degrees/37 degrees Celsius" +
   "Anything above 98.6 degrees Fahrenheit/37 degrees Celsius is abnormal.");

   } else if(message =="Race") {
       alert("African Americans have a higher chance of lung cancer" + 'n\n' + "Followed by Caucasians" +
   "Asians, Pacific Islanders, Hispanics, and Native Americans have a low percentage.");


   }
   else if(message == "family") {
      alert("Family History of Lung Cancer" + '\n\n' +
      "Choose Yes if an immediate family member had " +
      "lung cancer.");

      "Note: The Calculator is only applicable for persons without a previous diagnosis of lung cancer.");

   }
}

我为你设置了一个jsfiddle。您可以插入您的逻辑来计算剩余字段的风险并清理 html。

JavaScript

var risk = {
    'none': 0,
    'low': 1,
    'high': 2,
    'abnormal': 3
};

var myRsk = 0;

function getValue(name) {
    return document.getElementsByName(name)[0].value;
}

function calculateRisk() {
    age = getValue('iAge');
    gender = getValue('iGender');
    sbp = getValue('iSBP');
    dbp = getValue('iDBP');
    temp = getValue('iTemp');
    race = getValue('iRace');
    family = getValue('iFamily');

    myRisk = 0;
    myRisk += calculateAge(age);
    myRisk += calculateGender(gender);
    myRisk += calculateSBP(sbp);
    myRisk += calculateDBP(sbp);
    myRisk += calculateTemp(temp);
    myRisk += calculateRace(race);
    myRisk += calculateFamily(family);
    myRisk = parseFloat(myRisk / 21 * 100).toPrecision(4);

    alert('Your Risk = ' + myRisk + '%');
}

function calculateAge(age) {
    val = parseInt(age)
    if (val > 80) return risk['abnormal'];
    else if (val > 60) return risk['high'];
    else if (val > 40) return risk['low'];
    else return parseInt(risk['none']);
}

function calculateGender(gender) {
    return parseInt(risk['low']);
}

function calculateSBP(sbp) {
    return parseInt(risk['low']);
}

function calculateDBP(dbp) {
    return parseInt(risk['low']);
}

function calculateTemp(temp) {
    return parseInt(risk['low']);
}

function calculateRace(race) {
    return parseInt(risk['low']);
}

function calculateFamily(family) {
    return parseInt(risk['low']);
}
