我的程序需要包含一个 for 循环，使用已经创建的两个输入函数（名称和数字），并且需要获取总数。我还需要能够取消并转到我的 doc.write，我将在其中输入姓名和号码。我还需要给用户另一个机会来输入他们的姓名或号码，如果他们不小心输入了字母应该是的数字，反之亦然。我认为我的大部分结构都是正确的，任何帮助将不胜感激！

function inputName() {

var nameIn = prompt("Enter your Name");
while(!isNaN(nameIn)) {
nameIn = prompt("Must contain only letters");


}
return nameIn;

}
/* INPUT NUMBER */

 function inputNum(){

var numIn=parseFloat(prompt("Enter the number of hours worked \n 0-60 hours"));

var min=0;
var max=60;

while(numIn>min && numIn>max ){
numIn=prompt("Enter a valid number between 0-60");
return numIn;
}
</script>
<body>


<script type="text/javascript">

//DECLARATIONS
var wage=10.00;
var earned; // hrsWrked*wage
var totHrsWrked=0;
var totEarning=0;
var BR= "
";
var howMany;
var loopControl;

//INPUT & PROCESSING

howMany=parseFloat(prompt("How many employees are you inputing?"));

for(loopControl=1 ; loopControl <= howMany; ++loopControl){

var inpNam=inputName();

var inpNumber=inputNum();


earned= inpNumber*wage;
totEarning+=earned;
totHrsWrked+=inpNumber;

//OUTPUT
document.write("Name: "+ inpNam+ BR);
document.write("Hours Worked: " + inpNumber + BR);
document.write("Money Earned: $ " + earned + BR +BR);

}
document.write("Total Hours Worked: " + totHrsWrked.toFixed(2) + BR);
document.write("Total Earnings: " + "$"+totEarning.toFixed(2)+ BR+BR);

</script>
</body>

这是您的代码的编辑版本。:)

<! doctype html>
<html>
<body>
<script>

//DECLARATIONS
var wage=10.00, earned, totHrsWrked=0, totEarning=0, howMany;

//INPUT & PROCESSING
howMany=parseFloat(prompt("No of employees"));
for( var loopControl=1 ; loopControl <= howMany; ++loopControl)
{

    var inpNam=inputName();
    var inpNumber=inputNum();   
    earned= inpNumber*wage;
    totEarning+= (+earned);
    totHrsWrked+= (+inpNumber);
    //OUTPUT
    document.write("Name: "+ inpNam+ "<br>");       
    document.write("\n Hours Worked: " + inpNumber + "<br>");
    document.write("Money Earned: $ " + earned + "<br><br>");
}
document.write("Total Hours Worked: " + totHrsWrked.toFixed(2)+ "<br>");
document.write("Total Earnings: " + "$"+totEarning.toFixed(2)+ "<br>");

//INPUT NAME 
function inputName() {

var nameIn = prompt("Enter your Name");
while(!isNaN(nameIn)) {
nameIn = prompt("Must contain only letters");
}
return nameIn;
}

//INPUT NUMBER 
function inputNum(){
var numIn=parseFloat(prompt("Enter the number of hours worked \n 0-60 hours"));
var min=0;
var max=60;

while(numIn<=min || numIn>=max ){
numIn=prompt("Enter a valid number between 0-60");
}
return numIn;
}
