gICAPI.Action()

The gICAPI.Action() function is used to perform an action in the current dialog.

Purpose of gICAPI.Action()

Use the gICAPI.Action("action-name") function in order to execute an action in the context of the current dialog.

This function takes the name of the action as parameter. The corresponding ON ACTION handler will be called.

Note:

Make sure that the parameter passed to gICAPI.action() matches the action name in lowercase letters.

If the named action is not available (if it does not exist, or if it is disabled), the gICAPI.Action() function has no effect.

After calling gICAPI.Action("action-name"), the gICAPI framework will perform a gICAPI.onFlushData() callback (if defined), to let you provide the web component field value with gICAPI.SetData().

However, if you do not use the gICAPI.onFlushData() callback, it is also possible to provide the value with gICAPI.SetData(), just before calling with gICAPI.Action().

Example 1: Using gICAPI.SetData() directly before gICAPI.Action()

The following code executes the "color_selected" action, after setting the value of the WEBCOMPONENT field with gICAPI.SetData():

var selectColor = function(c) {
    gICAPI.SetData(c);
    gICAPI.Action("color_selected");
}

// In the HTML code, an element defines the onclick handler as follows:
 ... onclick="selectColor('#FFFFCC')" ...

Example 2: Using gICAPI.Action() and gICAPI.onFlushData()

The following code executes the "color_selected" action, and sets the value of the WEBCOMPONENT field with gICAPI.SetData() in the gICAPI.onFlushData() callback:

var color = null;

var selectColor = function(c) {
    color = c;
    gICAPI.Action("color_selected");
}

gICAPI.onFlushData = function() {
    gICAPI.SetData(color);
}

// In the HTML code, an element defines the onclick handler as follows:
 ... onclick="selectColor('#FFFFCC')" ...

Action handler in program code

In the program code, define an ON ACTION block in a dialog instruction, to execute code when the corresponding web component action is fired.
Note:

WEBCOMPONENT actions are not known by the front-end. A default action view will be created for each ON ACTION handler. Consider using the DEFAULTVIEW=NO action attribute, in order to avoid default action views being displayed for your web component actions.

  ON ACTION color_selected ATTRIBUTES( DEFAULTVIEW=NO )
     IF rec.webcomp == "#000000" THEN
        LET rec.webcomp = rec.pgcolor
        LET rec.info = NULL
        ERROR "Black color is denied!"
     ELSE
        LET rec.pgcolor = rec.webcomp
        LET rec.info = "Color selected:", rec.pgcolor
     END IF
