我如何在Javascript中分配数字
How can I assign numbers in Javascript?
我正在用Javascript构建一个风险计算器程序，对于它，我有1-3的等级，0表示没有风险，3表示最高风险。对于每一个选项(年龄、性别、身体质量指数、血压、体温、吸烟情况等)，我将给它们分配一个数字(0-3)，并用这个数字来确定风险的百分比。
例子:年龄:
18-39 = 0
40+ = 2风险
用户选择的年龄将加到他们的个人百分比中。
如何编写这个程序?
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。您只需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']);
