Interface IHtmlDialogContext
The IHtmlDialogContext specifies the interface of the ivy.html
environment variable.
This environment variable / interface provides methods to generate form
controls, build links, format process attributes and many other useful things
for HTML process pages. All these methods will mostly be used as macros
inside process pages
(e.g. <a href="<%=ivy.html.ref("LinkA.ivp")%>">My Link</a>)
Use the HtmlDialogContextFactory
to create a new object that
implements this interface

wr
Creates a link to a file in the static webContent folder of the current project. This method is useful to refer to e.g. JavaScript extensions or other static web content. For images, banners and labels it is recommended to link to content management system entries.
Only the current project's webContent folder will be searched. The webContent folders of any required projects will not be taken into consideration.
Example: An argument such as
myDir/myStyle.css
will reference.../webContent/myDir/myStyle.css
.Important Note: This method is not really needed. You can address all webContent files of a project with a link that is relative to the current JSP page.
Example: A link
<a href="myDir/myStyle.css">MyLink</a>
on a JSP page will have exactly the same effect as<a href="<%=ivy.html.wr("myDir/myStyle.css")%>">MyLink</a>
. Obviously the version without macro is much simpler and better readable and thus recommended.- Parameters:
relativeWebContentUri
- relative URI to a file in webContent folder, e.g.myDir/myStyle.css

- a valid URL reference to the file in your project's "webContent" folder
