Constructors

ScriptTagHelper(IWebHostEnvironment, TagHelperMemoryCacheProvider, IFileVersionProvider, HtmlEncoder, JavaScriptEncoder, IUrlHelperFactory)

Creates a new ScriptTagHelper.

Properties

AppendVersion	Value indicating if file version should be appended to src urls.
Cache	Gets the IMemoryCache used to store globbed urls.
FallbackSrc	The URL of a Script tag to fallback to in the case the primary one fails.
FallbackSrcExclude	A comma separated list of globbed file patterns of JavaScript scripts to exclude from the fallback list, in the case the primary one fails. The glob patterns are assessed relative to the application's 'webroot' setting. Must be used in conjunction with FallbackSrcInclude.
FallbackSrcInclude	A comma separated list of globbed file patterns of JavaScript scripts to fallback to in the case the primary one fails. The glob patterns are assessed relative to the application's 'webroot' setting.
FallbackTestExpression	The script method defined in the primary script to use for the fallback test.
GlobbingUrlBuilder	Gets the GlobbingUrlBuilder used to populate included and excluded urls.
HostingEnvironment	Gets the IWebHostEnvironment for the application.
HtmlEncoder	The HtmlEncoder. (Inherited from UrlResolutionTagHelper)
JavaScriptEncoder	Gets the JavaScriptEncoder used to encode fallback information.
Order	When a set of ITagHelpers are executed, their Init(TagHelperContext)'s are first invoked in the specified Order; then their ProcessAsync(TagHelperContext, TagHelperOutput)'s are invoked in the specified Order. Lower values are executed first.
Src	Address of the external script to use.
SrcExclude	A comma separated list of globbed file patterns of JavaScript scripts to exclude from loading. The glob patterns are assessed relative to the application's 'webroot' setting. Must be used in conjunction with SrcInclude.
SrcInclude	A comma separated list of globbed file patterns of JavaScript scripts to load. The glob patterns are assessed relative to the application's 'webroot' setting.
SuppressFallbackIntegrity	Boolean value that determines if an integrity hash will be compared with FallbackSrc value.
UrlHelperFactory	The IUrlHelperFactory. (Inherited from UrlResolutionTagHelper)
ViewContext	The ViewContext. (Inherited from UrlResolutionTagHelper)

Methods

Init(TagHelperContext)	Initializes the ITagHelper with the given context. Additions to Items should be done within this method to ensure they're added prior to executing the children. (Inherited from TagHelper)
Process(TagHelperContext, TagHelperOutput)	Synchronously executes the TagHelper with the given context and output.
ProcessAsync(TagHelperContext, TagHelperOutput)	Asynchronously executes the TagHelper with the given context and output. (Inherited from TagHelper)
ProcessUrlAttribute(String, TagHelperOutput)	Resolves and updates URL values starting with '~/' (relative to the application's 'webroot' setting) for output's Attributes whose Name is attributeName. (Inherited from UrlResolutionTagHelper)
TryResolveUrl(String, IHtmlContent)	Tries to resolve the given url value relative to the application's 'webroot' setting. (Inherited from UrlResolutionTagHelper)
TryResolveUrl(String, String)	Tries to resolve the given url value relative to the application's 'webroot' setting. (Inherited from UrlResolutionTagHelper)
