AEM Forms enables form authors to further simplify and enhance the form filling experience by invoking services configured in a form data model from within an adaptive form field. To invoke a data model service, you can either create a rule in the visual editor or specify a JavaScript using the guidelib.dataIntegrationUtils.executeOperation API in the code editor of the rule editor.
This document focuses on writing a JavaScript using the guidelib.dataIntegrationUtils.executeOperation API to invoke a service.
The guidelib.dataIntegrationUtils.executeOperation API invokes a service from within an adaptive form field. The API syntax is as follows:
guidelib.dataIntegrationUtils.executeOperation(operationInfo, inputs, outputs)
| Parameter | Description |
|---|---|
| operationInfo | Structure to specify form data model identifier, operation title, and operation name |
| inputs | Structure to specify form objects whose values are input to the service operation |
| outputs | Structure to specify form objects that will be populated with the values returned by the service operation |
The structure of the guidelib.dataIntegrationUtils.executeOperation API specifies details about the service operation. The syntax of the structure is as follows.
var operationInfo = {
formDataModelId,
operationTitle,
operationName
};
var inputs = {
inputField1,
inputFieldN
};
var outputs = {
outputField1,
outputFieldN
}
| Parameter | Description |
|---|---|
| forDataModelId | Specify the repository path to the form data model including its name |
| operationName | Specify the name of the service operation to execute |
| input | Map one or more form objects to the input arguments for the service operation |
| Output | Map one or more form objects to output values from the service operation to populate form fields |
The following sample script uses the guidelib.dataIntegrationUtils.executeOperation API to invoke the getAccountById service operation configured in the employeeAccount form data model.
The getAccountById operation takes the value in the employeeID form field as input for the empId argument and returns employee name, account number, and account balance for the corresponding employee. The output values are populated in the specified form fields. For example, the value in name argument is populated in the fullName form element and value for accountNumber argument in account form element.
var operationInfo = {
"formDataModelId": "/content/dam/formsanddocuments-fdm/employeeAccount",
"operationName": "getAccountDetails"
};
var inputs = {
"empid" : employeeID
};
var outputs = {
"name" : fullName,
"accountNumber" : account,
"balance" : balance
};
guidelib.dataIntegrationUtils.executeOperation(operationInfo, inputs, outputs);
