所以这是一个简单的 javascript 代码，它将数字中的钱变成了单词。问题是浏览器甚至没有提示窗口。我已经阅读了很多次代码，但我无法找到错误。任何人都可以帮忙吗？

<script type="text/javascript">
        document.writeln("hello World");
    var output=new Array("Rs.",null,null,null,null,null,null,null,null,null,null,null,null,null,null);

        n1=parseFloat(str);
        if(isNaN(n1))

         docucument.writeln("Enter a Valid number");
         return;
        }
        else
        {

Get rid of the else { in the two_digit() function. There is a bracket missing (and the else is not necessary in the code since you always return in the if before it).

Also get rid of the first return in the code. A return cannot be used outside of a function (if you want a quick but "wrong" way to exit, you can use throw 'End'; but that is really only supposed to be used for errors).

You have two syntax errors that I found:
1. You have a return statement - outside a function, and
2. You're missing a closing }

Suggestion:
You should add line-breaks <br> in the test that you print to screen.

The following fixed code works for me:

    <script type="text/javascript">
            document.writeln("hello World");
            var output=new Array("Rs.",null,null,null,null,null,null,null,null,null,null,null,null,null,null);

            str=window.prompt("Enter a number:","0");
            n1=parseFloat(str);
            if(isNaN(n1))
            {
             docucument.writeln("Enter a Valid number");
            }
            else
            {
                paise=(n1%1)*100;
                rupee=parseInt(str);
                output[14]="paise only";

                output[13]=two_digit(paise);

                output[12]="and";
                x=rupee%100;
                output[11]=two_digit(x);
                rupee=rupee/100;
                //if(rupee<=0) break end;

                output[10]="hundred";
                x=rupee%10;
                output[9]=one_digit(x);
                rupee=rupee/10;
                //if(rupee<=0) break end;

                output[8]="thousand";
                x=rupee%100;
                output[7]=two_digit(x);
