Defines a resource in an assembly to be used from a client script file. This class cannot be inherited.

public ref class ScriptResourceAttribute sealed : Attribute

[System.AttributeUsage(System.AttributeTargets.Assembly, AllowMultiple=true)]

Examples

The following example shows a ScriptResourceAttribute attribute for a script file named CheckAnswer.js that uses resources from the VerificationResources resource files. The name Answer is used to reference these resources.

[assembly: System.Web.UI.WebResource("LocalizingScriptResources.CheckAnswer.js", "application/x-javascript")]
[assembly: System.Web.UI.ScriptResource("LocalizingScriptResources.CheckAnswer.js", "LocalizingScriptResources.VerificationResources", "Answer")]

<Assembly: System.Web.UI.WebResource("LocalizingScriptResources.CheckAnswer.js", "application/x-javascript")> 
<Assembly: System.Web.UI.ScriptResource("LocalizingScriptResources.CheckAnswer.js", "LocalizingScriptResources.VerificationResources", "Answer")>

The following example shows how to use the resources in client script. The resource keys (Correct and Incorrect) are prefixed with Answer to identify the script resource definition that contains the values.

function CheckAnswer()
{
    var firstInt = $get('firstNumber').innerText;
    var secondInt = $get('secondNumber').innerText;
    var userAnswer = $get('userAnswer');
    
    if ((Number.parseLocale(firstInt) + Number.parseLocale(secondInt)) == userAnswer.value)
    {
        alert(Answer.Correct);
        return true;
    }
    else
    {
        alert(Answer.Incorrect);
        return false;
    }
}

Remarks

The ScriptResourceAttribute class is valid only when you use it in assembly declarations. You use it to enable a specified embedded script resource in an assembly. You can define the name of the embedded script library, the name of the resource file for the script library, and the name that is used in a script file for retrieving the resource values. The ScriptManager class uses the properties in ScriptResourceAttribute to determine the correct resource name for a script library. The TypeName property is used with a resource key to specify a resource.

Note

The ScriptResourceAttribute class can be used only to identify text-based resources for JavaScript files. To associate a localized image (binary) file with a particular culture, consider storing only its URL as a localized resource, which then be resolved and loaded in script.

Constructors

ScriptResourceAttribute(String, String, String)	Initializes a new instance of the ScriptResourceAttribute class.
ScriptResourceAttribute(String)	Initializes a new instance of the ScriptResourceAttribute class.

Properties

ScriptName	Gets the name of the script library.
ScriptResourceName	Obsolete. Gets the name of the resource file for the script library.
StringResourceClientTypeName	Gets the name of the client type to create for the values in the resource file.
StringResourceName	Gets the name of the resource file for the script library.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)
TypeName	Obsolete. Gets the name that is used when retrieving the values in the resource file.

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object. (Inherited from Attribute)
