XForms/Load

Motivation
You want to load a new resource over your current form.

Usage
In HTML links are simple. You use the HTML anchor tag

However, in XForms, it is a bit more complex:

The XForms xf:load element has several attributes.


 * ref - a static reference to a single node
 * resource - a static URL such as a relative or absolute URL
 * show - if a new page is created or the current page replaced. Show can have two values: new or replace.
 * target - the target action to be executed

One is the URI of the resource to load and the other is the show attribute. The show attribute can have values of "replace" which will replace the current form with the new resource and "new" which will open a new tab in your web browser or a new window if you are running older browsers such as IE 6.

xf:load can also be used to run a local javascript function when a form loads:

Loading Dynamic Strings
Note that the ref attribute of xf:load can only be a static string. You can not change this as the XForms application changes.

If you need to load dynamic string the way to do this is to use the xf:resource element within the xf:load element. The xf:resource element has a value attribute that is used to hold all the dynamic expressions.

For example, the following example concats a URL and the search query from an input field.

Load with resource attribute value templates
Some implementations allow you to dynamically create URLs based on data in our mode.
