Uncaught TypeError: elements.appendChild is not a function at show2

这个错误消息表示 `elements.appendChild` 不是一个函数。
根据您提供的代码片段,可能是因为 `elements` 不是一个 DOM 元素。`appendChild` 方法用于向 DOM 元素中添加子元素,因此 `elements` 必须是一个正确的 DOM 元素才能调用该方法。
请确保 `elements` 是一个有效的 DOM 元素。您可以使用 `console.log(elements)` 来查看 `elements` 的值,确保它是一个 DOM 元素。如果不是,则需要检查代码中获取 `elements` 的过程,并确保它引用了正确的 DOM 元素。

Uncaught TypeError: window.showModalDialog is not a function错误的原因是谷歌浏览器已经不支持window.showModalDialog方法了。为了解决这个问题,你可以使用兼容谷歌浏览器的方法来自定义一个模态窗口。下面是一个示例代码:
```javascript
if (!window.showModalDialog) {
window.showModalDialog = function(url, name, options) {
if (window.hasOpenWindow) {
window.newWindow.focus();
}
var re = new RegExp(";", "g");
options = options.replace(re, '","');
options = '{"' + options.replace(/:/g, '":"') + '"}';
options = JSON.parse(options);
var openOptions =
"width=" +
parseInt(options.dialogWidth) +
",height=" +
parseInt(options.dialogHeight) +
",left=" +
(window.screen.width - parseInt(options.dialogWidth)) / 2 +
",top=" +
(window.screen.height - 30 - parseInt(options.dialogHeight)) / 2; window.hasOpenWindow = true;
window.newWindow = window.open(url, name, openOptions);
};
}
function showModal() {
window.showModalDialog(
"http://www.baidu.com",
window,
"dialogWidth:500px;dialogHeight:550px"
);
}

Uncaught TypeError: document. forms is not a function
The error message "Uncaught TypeError: document.forms is not a function" means that you are trying to use the method "forms()" on the "document" object, but it is not a function.
Here are a few possible reasons for this error:
1. The "forms" property may not be defined on the "document" object in your browser or environment.
2. There may be a conflict with another script that is redefining or overwriting the "document.forms" method.
3. There may be a syntax error or typo in your code that is causing the error.
To resolve this error, you can try the following steps:
1. Check your code for any syntax errors or typos that may be causing the problem.
2. Make sure that the "forms" property is supported on the "document" object in your browser or environment.
3. Try renaming the "forms" property to something else to avoid conflicts with other scripts. For example, you could use "myForms" instead of "forms".
4. Try using a different method or property to access the forms on the page, such as "document.getElementsByTagName('form')" or "document.querySelectorAll('form')".
