Deprecated feature: Tag: declareService

The wcf:declareService tag adds client-side support for invoking a service request. The ID is used to register the specified service so it can be invoked with the wc.service.invoke(serviceId, parameters) function. The parameters parameter is an object map that is passed as parameters to the service URL.

Instead of using the wcf:declareService tag, write JavaScript code.

Attributes

Attributes
Name	Required	Type	Description
`id`	`true`	String	The service ID.
`actionId`	`true`	String	The action identifier that is used to uniquely identify the action that is performed by this service.
`url`	`true`	String	The URL to process this service.
`formId`	`false`	String	The element ID of the form that is to be submitted to this service.
`validateParametersScript`	`false`	JSP fragment	JavaScript that validates the parameters that are being passed to this request. This script must be composed by a developer. The script uses the local variable `parameters` , which is the Object map of parameters that were passed to the service. The script can also update a local variable that is called `valid` to `false` to indicate that the request must be stopped. If this attribute is not specified, then the parameters are always considered to be valid.
`validateFormScript`	`false`	JSP fragment	JavaScript that validates the form that is specified by the `formId`. This script must be composed by a developer. The script uses the local variable `formNode`, which is the form node that is extracted from the document. The script can also update a local variable that is called `valid` to `false` to indicate that the request must be stopped. If this attribute is not specified, then the form is always considered to be valid.
`successTestScript`	`false`	JSP fragment	JavaScript that examines the service response object to determine whether the request was successful or not. The script uses the local variable `serviceResponse` , which is the service response object. The script must also update a local variable that is called `success` to `false` to indicate that the request was not successful. This result determines whether the success handler or the failure handler is invoked. If this attribute is not specified, then the service response Object is tested to see whether there is a property that is called `errorCode`. If the `errorCode` property exists, then the service request is treated as a failed request.
`successHandlerScript`	`false`	JSP fragment	JavaScript that is run after the successful invocation of the service request. The script can use the local variable `serviceResponse`, which is an Object that contains the service response map.
`failureHandlerScript`	`false`	JSP fragment	JavaScript that is run after a failed invocation of the service request. The script can use the local variable `serviceResponse` , which is an Object that contains the service response map.

 url="AjaxDeleteOrderItem">
</wcf:declareService>
