在 Visualstudio (MacOS) 上运行 javascript 以编写 Web 开发时遇到问题？

Question

I'm learning to write javascript and here is the code:我正在学习编写 javascript，这是代码：

 <!DOCTYPE html Public "-//W3C//DTD XHTML 1.0 Transitional //EN"
          "http://www.w3.org/TR/xhtmll/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Chapter 7: Example 1</title>
    <script type="text/javascript">
        function window_onload()
        {
            var numberForms = document.forms.length;
            var formindex;
            for (formIndex = 0; formIndex < numberForms; formIndex++}
            {
                alert(document.forms(formIndex).name);
        }
        ]
    </script>
</head>
<body onload="window_onload()">
    <form action="" name="form1">
        <p>
            This is inside form1.
        </p>
    </form>
    <form action="" name="form2">
        <p>
            This is inside form2
        </p>
    </form>
    <form action="" name="form3">
        <p>
            This is inside form3
        </p>
    </form>
</body>
</html>

I have saved the file as a.html, .js and a.htm and had no luck in getting it up and running when opening the browser and I'm looking for a reason why this has happened.我已将文件保存为 a.html、.js 和 a.htm，但在打开浏览器时无法启动并运行它，我正在寻找发生这种情况的原因。

Answer 1

You've got several syntax errors.你有几个语法错误。 In the window_onload function you have a } instead of a closing ) .在window_onload function 你有一个}而不是关闭) 。

There's also a random ] at the very end of the function and your function is missing a closing )在 function 的最后还有一个随机的] ，而您的 function 缺少关闭)
