html form image,html 标签: image也能提交form!!!

不完全正确。HTML中的`<img>`标签本身并不能用于提交表单数据,因为它只是用于显示图像的标签。但是,可以将图像作为表单的背景,然后在其上放置一个透明的`<input>`标签,这样当用户单击图像时,实际上是单击了该`<input>`标签,从而触发了表单的提交操作。这种方式称为图像作为表单按钮(Image Button)。
示例代码如下:
```
<form action="submit.php" method="post">
<input type="image" src="submit.png" alt="Submit" name="submit">
</form>
```
在上面的示例中,`<input>`标签的`type`属性设置为`"image"`,并指定了要显示的图像的地址。当用户单击该图像时,将提交表单数据到`submit.php`页面,并将该`<input>`标签的`name`属性设置为`"submit"`,以便在后台处理程序中识别该按钮。

html form标签添加背景的代码
可以使用CSS来为form标签添加背景,例如:
```html
<form style="background-image: url('background.jpg');">
<!-- form content -->
</form>
```
或者将CSS样式写在`<style>`标签或外部CSS文件中:
```html
<style>
form {
background-image: url('background.jpg');
}
</style>
<form>
<!-- form content -->
</form>
```
AttributeError: type object 'QPixmap' has no attribute 'formImage'
The error message suggests that you are calling the 'formImage' method on the QPixmap class, but that method does not exist.
There is no 'formImage' method in the QPixmap class. Perhaps you meant to call 'toImage' instead, which returns a QImage object representing the pixmap.
Here's an example:
```python
from PyQt5.QtGui import QPixmap
# create a pixmap
pixmap = QPixmap('image.jpg')
# convert the pixmap to a QImage
image = pixmap.toImage()
```
This will create a QPixmap object from the image file 'image.jpg', and then convert it to a QImage using the 'toImage' method.
