Link builder inputs

This topic describes the inputs for the Link builder.

 

General inputs

Table 1. General inputs
Input Name Description
Name Name for this builder call. The WebSphere Portlet Factory Designer displays this name in the builder call list.
Page Location Page or pages on which this builder call acts.
Link text Specify a value to display as the link text. You can specify an indirect reference with the Choose Reference dialog, or enter a text string directly.
Action type Defines the behavior of the action. Choose an action type based on the action that will process the onClick event and if you want to process any form inputs as part of that action.

Submit form and invoke action

Choose this option if the specified action is a method in the model or linked Java™ object and that method processes the inputs to the form on which the button resides.

Submit form to URL

Choose this option if the specified action is a URL outside of the IBM® WebSphere Portlet Factory runtime that will process the inputs to a form. The specified URL receives the form input values as name/value pairs appended to the URL.

Link to an Action

Choose this option if the specified action is a method in the model or linked Java object (including service calls). Acts as a simple link, transferring control directly to the specified Action. The specified action cannot process any form inputs.

Link to a URL

Choose this option if you want to navigate to a non- WebSphere Portlet Factory URL. Acts as a simple link, transferring control directly to the specified URL. The URL cannot process any form inputs.

Run a script

Choose this option of you want to run some client-side JavaScript™ when the user clicks on the button. The script cannot process any form inputs.
Action Specify the model action or external URL to which to link.
Script to Execute Applies only if you selected Run a script as the value for Action Type.

JavaScript to link to when the user clicks on the link text. Form inputs, if any, are not submitted to a script.

Note: Do not use comments in the script you specify. The script you specify is added as one line, so any code following comments is ignored.

Form Name If the link is in one form or frame and the form to be submitted is in another, enter the name of the form whose inputs you want to submit.

 

Arguments

Table 2. Arguments input
Input Name Description
Input mappings You can pass arguments to the specified action by adding argument names and the value to be passed to it. Use the Choose Reference dialog to specify input values or values returned by methods or service calls as the value to be passed to an argument for the specified action.

 

HTML Attributes

Table 3. HTML Attributes inputs
Input Name Description
Class The value for the HTML class attribute. The class attribute specifies the element to be a member of one or more classes.
Style The value for the HTML style attribute. The style attribute allows authors to specify the style rules inline for a single occurrence of an element.

 

Post-Action Behavior

Table 4. Post-Action Behavior inputs
Input Name Description
Post-Action Behavior Select what happens after the action launched by the link completes.

Default

In most cases this displays the output generated by the action. One exception to this is when the action is run from inside a container that specifies that the outermost page gets rendered after the action runs. In the exception case, default would not display the output, but refresh the outermost page.

Refresh specified page location after running action

The outermost page is not refreshed. Instead, new HTML for the specified region is recalculated after the action runs, and this HTML is sent to the client where it replaces the existing HTML. If Replace "id" Matches is checked, then the HTML produced by the action is examined for elements that have ID attribute values. If ID attribute values are found, then the corresponding elements in the page will have their HTML replaced.

Note: If Ajax is disabled, the default post-action behavior is used without loss of functionality. Ajax enablement is controlled through the Global Ajax Enablement builder and profiling rather than changing inputs in a large number of builders.

Replace specified location with action results

This is good for ToolTips, incremental validation, and other simple information calculated on the server.

Evaluate action results as JavaScript

Run the main action, and evaluate what it returns as JavaScript.

Always reload top-most page after running action

This is very similar to default, but overrides behavior that prevents the top-most page from refreshing. This option would be necessary if portal event and render phases need to be carried out to enable portlet-to-portlet communication to function properly.

Show action results "stand-alone": display no containing pages

This option is similar to default, but it ensures that even if the model is running in a portal or model container, the action only returns the results of the specified action, not the containing portal or other surrounding pages. This option is ideal for lower-level Ajax or related functionality such as pop-ups, computed images, or Excel export.
Execute Embedded Scripts This input is available if the Post-Action Behavior input is set to Refresh specified page after running action.

Set this input to execute any JavaScript present in the page that is being refreshed. Any script specified either by <script src="name" /> or as text inside a <script> section is executed.

 

Advanced

Table 5. Advanced inputs
Input Name Description
Target The window or frame which displays the results of the action. If you do not set this value, the current window or frame is the target. Valid entries for the target value include the following:

_self

Display results in the frame containing the form. If target is not specified, _self is the default.

_blank

Display results in a new browser window.

_parent

Display results in the frameset above the frame containing the form.

_top

Display results the topmost frameset.
You can also specify the name of a frame in the current frameset.

Note: All of these targets are relative to the form being processed, not the control itself.

Rendering Mode Determines if the outermost page is to be rendered after running the action. Valid entries include the following:

Normal

Render normally.

Render outermost page after running action

Break containment Determines if the element is run as a top-level action, even if contained, for example, in a portal.
