Summary

用于图片显示的元素,与HTML中的img相似.使用 src可以指定图片的URL.

More information is available in the XUL tutorial.

Note: Prior to Gecko 8.0, images did not shrink down with the same ratio in both directions when specifying maximum sizes using maxheight or maxwidth. The new behavior aligns more with the HTML <img> element and shrinks both the width and height down proportionally.

Attributes: onerror, onload, src, validate

Properties: accessibleType, src

Style classes: alert-icon, error-icon, message-icon, question-icon

Examples

<image src='Firefoxlogo.png' width='135' height='130'/>

Attributes

onerror: Type: script code; This event is sent to an image element when an error occurs loading the image.

onload: Type: script code; This event handler will be called on the image element when the image has finished loading. This applies whether the image is applied via the src attribute or the list-style-image style property. If you change the image, the event will fire again when the new image loads. This event will not bubble up the element tree.

src: Type: URI; The URI of the content to appear in the element.

validate

Type: one of the values below

This attribute indicates whether to load the image from the cache or not. This would be useful if the images are stored remotely or you plan on swapping the image frequently. The following values are accepted, or leave out the attribute entirely for default handling:

always: The image is always checked to see whether it should be reloaded.
never: The image will be loaded from the cache if possible.

Properties

accessibleType: Type: integer; A value indicating the type of accessibility object for the element.

src: Type: URL; Gets and sets the value of the src attribute.
