具有范围输入值的 Javascript 条件语句

Question

有人可以帮助我编写以下 Javascript 代码吗？如果“分数”的值在 1-3、3-5、5-7、7-9 和 9-10 之间，我希望执行条件语句。

目前，它们仅在变量“score”为整数时执行，但我希望分数在数字范围内执行。

例如，我希望“if ((score==1) || (score==2) || (score==3))”这一行类似于 if( score 在 1 和 3 之间) , 那么语句就会被执行。

这是 HTML:

Input 1 <input type="number" id="num1">
    <br>
    <br>
    Input 2 <input type="number" id="num2">
    <br>
    <br>
    Input 3 <input type="number" id="num3">
    <br>
    <br>
    Input 4 <input type="number" id="num4">
    <br>
    <br>
    Input 5 <input type="number" id="num5">
    <br>
    <br>
    <button onclick="calculate()">Calculate</button>

<h1 id="answer"></h1>
<h1 id="advice"></h1>

这是 JS:

            function calculate()
        {
         var field1=document.getElementById("num1").value;
         var field2=document.getElementById("num2").value;
         var field3=document.getElementById("num3").value;
         var field4=document.getElementById("num4").value;
         var field5=document.getElementById("num5").value;

         if ( (field1>10) || (field1<1)|| (field2>10) || (field2<1) || (field3>10) || (field3<1) || (field4>10) || (field4<1) || (field5>10) || (field5<1))

         {
            alert("Enter a number between 1 and 10");
            return false;
        }

         var result=parseFloat(field1)+parseFloat(field2)+parseFloat(field3)+parseFloat(field4)+parseFloat(field5);

         var score= result / 5;




            if ((score==1) || (score==2) || (score==3))

         {

            document.getElementById("advice").innerHTML="You are between 1 and 3";

            }

            if ((score==4) || (score==5))

         {

            document.getElementById("advice").innerHTML="You are between 4 and 5";

            }

            if ((score==6) || (score==7))

         {

            document.getElementById("advice").innerHTML="You are between 6 and 7";

            }

            if ((score==8) || (score==9))

         {

            document.getElementById("advice").innerHTML="You are between 8 and 9";

            }

            if ((score==10))

         {

            document.getElementById("advice").innerHTML="You are 10";

            }

         if(!isNaN(score))

            {

            document.getElementById("answer").innerHTML="Your career score is " + score;

            }


        }

非常感谢您的帮助!

Answer 1

if (score >= 1 && score < 3) {
  // do something
} else if (score >= 3 && score < 5) {
  // do something
}
 ... and so on
