Syntax
Members
| Member name | Value | Description | |
|---|---|---|---|
| Link | 0 | Source is a link click or the JavaScript window.open function. This is also the default value for requests like sub-resource loads that are not navigations. | |
| Explicit | 1 | Source is some other "explicit" navigation action such as creating a new browser or using the LoadURL function. This is also the default value for navigations where the actual type is unknown. | |
| AutoSubframe | 3 | Source is a subframe navigation. This is any content that is automatically loaded in a non-toplevel frame. For example, if a page consists of several frames containing ads, those ad URLs will have this transition type. The user may not even realize the content in these pages is a separate frame, so may not care about the URL. | |
| ManualSubframe | 4 | Source is a subframe navigation explicitly requested by the user that will generate new navigation entries in the back/forward list. These are probably more important than frames that were automatically loaded in the background because the user probably cares about the fact that this link was loaded. | |
| FormSubmit | 7 | Source is a form submission by the user. NOTE: In some situations submitting a form does not result in this transition type. This can happen if the form uses a script to submit the contents. | |
| Reload | 8 | Source is a "reload" of the page via the Reload function or by re-visiting the same URL. NOTE: This is distinct from the concept of whether a particular load uses "reload semantics" (i.e. bypasses cached data). | |
| SourceMask | 255 | General mask defining the bits used for the source values. | |
| BlockedFlag | 8388608 | Attempted to visit a URL but was blocked. | |
| ForwardBackFlag | 16777216 | Used the Forward or Back function to navigate among browsing history. | |
| ChainStartFlag | 268435456 | The beginning of a navigation chain. | |
| ChainEndFlag | 536870912 | The last transition in a redirect chain. | |
| ClientRedirectFlag | 1073741824 | Redirects caused by JavaScript or a meta refresh tag on the page. | |
| ServerRedirectFlag | 2147483648 | Redirects sent from the server by HTTP headers. | |
| IsRedirectMask | 3221225472 | Used to test whether a transition involves a redirect. | |
| QualifierMask | 4294967040 | General mask defining the bits used for the qualifiers. |
