Defining Web Behaviors of Objects in a Report

A web behavior contains a trigger event and a web action to be triggered when the event occurs on a specific object at runtime. By adding web behaviors to objects in your report, you can customize the objects to make them respond to interactive events, and execute corresponding web actions such as Sort and Filter. For example, you can associate a web action with an object's Click event, then at runtime, when users run the report and select the object, Server performs the specified operation. This topic describes the events you can use to trigger web actions and how you can specify the web behaviors of different objects in your report.

Generally, you can add web behaviors to basic web controls, labels, data fields, and special fields in a report. In a library component, you can also define web behaviors on chart elements and geographic map markers and areas.

Trigger Events of Web Actions

You can use the following events to trigger web actions.

Specifying Web Behaviors of a Web Control/Label/Field

You can specify the web behaviors of a basic web control while defining its web options, or of a label, data field, or special field while changing its display type, using the Display Type dialog box. However, for the basic web controls in the configuration panel of a library component, you need to use a different method to specify their web behaviors. See Using Basic Web Controls in Library Component Configuration Panel.

To specify the web behaviors of an object using the Display Type dialog box

1. In the Web Behaviors panel of the Display Type dialog box, choose an event from the Events column, then select in the Actions column and select the ellipsis.

   

2. In the Web Action List dialog box, select the required action and select OK. Designer displays different web actions in the dialog box according to the report type.

   

   • When you select one of the following web actions: Parameter, Filter, Sort, Property, Go Down, Go Up, Go To, Send Message, or Customized Control, Designer displays the corresponding web action builder dialog box for you to build the action.
   • When you select Customized Control from Lib, Designer displays the Manage Customized Controls dialog box, which shows all the customized control files in the customized control library. Select the one you want and select OK.
   • When you select a user-defined action which requires no parameter, for example, user_showTOC, Designer applies the action to the web control and closes the Web Action List dialog box. You can use this type of web actions in query-based page reports only.
   • When you select a user-defined action which needs parameters, for example, user_zoomTo, Designer displays the Parameters dialog box, which lists the parameters the web action requires. You can use this type of web actions in query-based page reports only. The following shows a sample dialog box.

     

     • Specify the parameter values in the Value column.
     • For parameters that refer to instance name, you can type the mapping name of the instance, or the display name plus the prefix "&" as the parameter value.
     • For more information about the parameter values, see Appendix 3: Parameters of User-Defined Web Actions.

   You can also define your own web actions by adding API functions into the file API.js located at <designer_install_root>\lib\html\javascript\dhtml and the same name file located at <server_install_root>\public_html\dhtmljsp\js.

3. Select Add in the Display Type dialog box and repeat the preceding steps to add more web behaviors to the object. To delete a web behavior, select it and select Remove.
4. Adjust the order of the web behaviors by selecting a web behavior and selecting Move Up or Move Down. Then, when an event that has been bound with more than one web action happens at runtime on the object, Server triggers the upper action first.

The following describes how to define a specific web action.

Applying the Parameter Web Action

You can use the Parameter web action to run a specified report, especially one with parameters using the predefined parameter values when the designated event occurs on the trigger object at runtime.

To define the Parameter web action

1. In the Web Action List dialog box, select *Parameter and select OK. Designer displays the Parameter - Web Action Builder dialog box.

   

2. Specify the handler which receives the parameters of the web action. The handler may be the default one in the current server, or in another server specified by Customized Path.
3. From the Get Input From drop-down list, specify where to get the input, which may be a form (available to page report only), a parameter form control in the report, or "Other in report".
4. In the Apply Action To section, specify how to apply the action.
   • If you want to apply the action to run a report, select Report and select Browse to specify the report in the current catalog that you want to run when the event occurs on the trigger object at runtime; or select Web Control and select a web control in the current report to retrieve the report name at runtime. Then from the Target Frame drop-down list, select the window or frame to open the report.
   • Select Refresh Current Report if you want to refresh the current report when the event occurs on the trigger object at runtime.
5. In the parameter box, specify the parameters and the values with which to run or refresh the current report.
   • When you select Report and specify a report, if the report contains parameters, Designer loads the parameters automatically into the parameter box. Edit the value for each parameter.
   • When you select Web Control or Refresh Current Report, Designer lists all the parameters used by the current report in the parameter box if it contains parameters. Edit the value for each parameter.
   • You can also use web controls in the current report to retrieve the name and value of a parameter from the values of the web controls at runtime.
6. Select Add to add more parameter lines to specify other parameter values. If you specify a parameter value more than once, the last setting takes effect.
7. To delete a parameter, select it and select Remove. You can also use Move Up and Move Down to adjust the order of the parameter lines.
8. Select OK to accept the parameter values.
