请您能帮我获取Java脚本中的if语句吗？
另外，我在我的消息变量中添加了指向新页面的链接，但是我认为这是不对的，对此，我们将不胜感激。

function displayMsg()
{
var age, bmi, family, sugar;
age = document.querySelector('input[name = "age"]:checked').value;
bmi = document.querySelector('input[name = "bmi"]:checked').value;
family = document.querySelector('input[name = "family"]:checked').value;
sugar = document.querySelector('input[name = "sugar"]:checked').value;
var total = age + bmi + family + sugar;
document.getElementById("container").innerHTML = "<b>Your result: </b><br>";
if( total >= 0 && total <= 15)
{
document.getElementById("container").innerHTML += messageLow;
}
else if(total >= 16 && total <= 25)
{
document.getElementById("container").innerHTML += messageMed;
}
elseif (total > 25)
{
if (age=>10 && bmi =>10)
}{
document.getElementById("container").innerHTML += messageHigh1;
}
{
if (age=>10 && family =>10)
}{
document.getElementById("container").innerHTML += messageHigh2;
}
{
if (age=>10 && sugar =>10)
}{
document.getElementById("container").innerHTML += messageHigh3;
}
{
if (bmi=>10 && family =>10)
}{
document.getElementById("container").innerHTML += messageHigh4;
}
{
if (bmi=>10 && sugar =>10)
}{
document.getElementById("container").innerHTML += messageHigh5;
}
{
if (family=>10 && sugar =>10)
}{
document.getElementById("container").innerHTML += messageHigh6;
}
else
{
break;
}
}
这是您的代码应如下所示：
if( total >= 0 && total <= 15){
document.getElementById("container").innerHTML += messageLow;
}else if(total >= 16 && total <= 25){
document.getElementById("container").innerHTML += messageMed;
}else if(total > 25){
if (age>=10 && bmi >=10){
document.getElementById("container").innerHTML += messageHigh1;
}else if(age>=10 && family >=10){
document.getElementById("container").innerHTML += messageHigh2;
}else if (age>=10 && sugar >=10) {
document.getElementById("container").innerHTML += messageHigh3;
}else if (bmi>=10 && family >=10){
document.getElementById("container").innerHTML += messageHigh4;
}else if (bmi>=10 && sugar >=10){
document.getElementById("container").innerHTML += messageHigh5;
}else if (family>=10 && sugar >=10){
document.getElementById("container").innerHTML += messageHigh6;
}
}
请注意，您仅将break用于循环或switch语句。您无需输入“;” 在if语句之后。它称为“条件”，而不是参数。参数被传递给函数。并且您不输入“;” 条件或条件之后的代码（“ {}”内的代码）将始终执行，即使不满足条件也是如此；
是“> =”而不是“ =>”
是“ else if”而不是“ elseif”
希望这对您有所帮助:)
