Question

作业要求而不是显示编号25,75,125,175，页面上应显示单词。我已经设置了if语句，但由于某种原因，我无法摆脱25,75,175的数量。请帮忙！

提前致谢。

在for循环的开头，您使用new_text += i;。这意味着它将始终将i附加到您的new_text字符串。如果你想让它成为条件，你需要把它放在else语句中。

   <script>
        //start of Assignment 2-1
        var new_text = "";
        var randMax = (Math.floor(Math.random() * 200));
        for (var i = 1; i < randMax; i++) {


            if (i == 25) {

                new_text = "Twenty Five ";

            } else if (i == 75) {
                new_text += "Seventy Five ";
            } else if (i == 125) {
                new_text += "one hundred and twenty five ";;
            } else if (i == 175) {
                new_text += "one hundred and Seventy five ";

            } else {
                new_text += i;
                new_text += " ";
            }

        }
        document.write(new_text);


    </script>

var new_text = "";
    var randMax = (Math.floor(Math.random() * 200));
    for (var i = 1; i < randMax; i++) {

        if (i == 25) {
            new_text += "Twenty Five ";
        } else if (i == 75) {
            new_text += "Seventy Five ";
        } else if (i == 125) {
            new_text += "one hundred and twenty five ";;
        } else if (i == 175) {
            new_text += "one hundred and Seventy five ";

        } else {
            new_text += i;
        }
        new_text += " ";

    }
    alert(new_text);

将“new_text + = i”移动到else块。现在无论条件如何，它都会在每次迭代时运行
