通过

HttpCapabilitiesBase.SupportsInputMode 属性

  • 参考

定义

命名空间:
System.Web.Configuration
程序集:
System.Web.dll

获取一个值，该值指示浏览器是否支持 HTML <input> 元素的 mode 特性。

public:
 virtual property bool SupportsInputMode { bool get(); };
public virtual bool SupportsInputMode { get; }
member this.SupportsInputMode : bool
Public Overridable ReadOnly Property SupportsInputMode As Boolean

属性值

Boolean

如果浏览器支持 HTML <input> 元素的 mode 属性，则为 true；否则为 false。 默认值为 false。

示例

下面的代码示例演示如何确定浏览器是否支持 mode HTML <input> 元素的属性。

注解

该 SupportsInputMode 属性仅适用于兼容 i 模式的设备。

该 MODE 属性用于在兼容 i 模式的浏览器中设置文本输入字段的输入模式。
