HttpCapabilitiesBase.CanRenderOneventAndPrevElementsTogether 属性
定义
获取一个值,该值指示浏览器是否支持共存于同一 WML 卡片中的 WML <onevent> 和 <prev> 元素。Gets a value indicating whether the browser supports WML <onevent> and <prev> elements that coexist within the same WML card.
public:
virtual property bool CanRenderOneventAndPrevElementsTogether { bool get(); };
public virtual bool CanRenderOneventAndPrevElementsTogether { get; }
member this.CanRenderOneventAndPrevElementsTogether : bool
Public Overridable ReadOnly Property CanRenderOneventAndPrevElementsTogether As Boolean
属性值
如果浏览器支持共存于同一 WML 卡片中的 WML true 和 <onevent> 元素,则为 <prev>;否则为 false。true if the browser supports WML <onevent> and <prev> elements that coexist within the same WML card; otherwise, false. 默认值为 true。The default is true.
示例
下面的代码示例演示如何确定浏览器是否支持在 <onevent> <prev> 同一 wml 卡片中共存的 wml 和元素。The following code example shows how to determine whether the browser supports WML <onevent> and <prev> elements that coexist within the same WML card.

注解
此 CanRenderOneventAndPrevElementsTogether 属性仅适用于 WML 兼容的移动设备。The CanRenderOneventAndPrevElementsTogether property applies only to WML-compatible mobile devices.
如果 false 为, <onevent> 则 <prev> 不会正确呈现同一 wml 卡片中的 wml 和元素。If false, WML <onevent> and <prev> elements that coexist within the same WML card will not be properly rendered.
