基本的Javascript程序，需要帮助

Basic Javascript Program, help need

本文关键字：帮助 程序 Javascript      更新时间：2023-09-26

我的程序需要由一个for循环组成，使用已经创建的输入函数（名称和数字）和总计。我还需要能够取消并转到我的doc.write，在那里输入名称和号码。如果用户不小心在字母应该在的地方输入数字，我还需要给用户另一个机会输入他们的名字或数字，反之亦然。我认为我拥有大部分结构正确，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>
</html>

这是代码的编辑版本。 :) 

<! 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;
}
</script>
</body>
