voltmx.os Namespace

The voltmx.os namespace provides functions for the Operating System API. It contains the following API elements:

• Constants
• Functions
• Objects

Constants

The voltmx.os Namespace contains the following types of constants.

Battery State Constants

---

These constants specify the current state of the device battery.

Constant	Description
BATTERY_STATE_CHARGING	Indicates that the state of the device battery as being charged.
BATTERY_STATE_DISCHARGING	Indicates that the state of the device battery as being discharged.
BATTERY_STATE_FULL	Indicates that the state of the device battery charge is completely full.
BATTERY_STATE_UNKNOWN	Indicates that the state of the device battery charge as not known.

Example

When you query for the state of the device battery as shown in this example, any of the four available battery states is returned.

var batteryState = voltmx.os.getBatteryState();

if (voltmx.os.BATTERY_STATE_CHARGING == batteryState) {

    voltmx.print(“Battery State: Charging”);
}

=======

Functions

The voltmx.os namespace contains the following functions.

voltmx.os.addHiddenField

---

This API helps the developers to pass dynamic values when the form needs to be submitted to external sites.

Syntax

addHiddenField([key](#key),[value](#value),[private](#private));

Input Parameters

Parameter	Description
key [String] - Mandatory	Specifies the key of the hidden field that you would like to add.
value [String] - Mandatory	Specifies the value that corresponds to the specified key in the hidden field.
private [String] - Optional	Specifies if the hidden field can be read using the voltmx.os.readHiddenField API. The expected values for this field are either "private" or "public". The default value of this field id "public". > Note: Only when this value is specified, you can read the hidden value through voltmx.os.readHiddenField API.

Example

function addHiddenField() {
    voltmx.os.addHiddenField("myhiddenfield", "myvalue", "private");
    // private value is specified and hence this hiddenfield can be read through the voltmx.os.readHiddenField API

            "autoStopSilenceTimeout": 60,
            "endSilenceTimeout": 80
        }
    });

voltmx.os.startSecureTransaction

---

This API can be invoked on an event of a widget. When this API is invoked it makes all the data and subsequent transactions of the application secure. For example, the login page of an application has the following: user name field, password field, and a button. On the onclick event of the button, the user is verified and navigated to pages with sensitive information. If you want to prevent cross site request forgery or double submissions, you can invoke this API ensuring that all the subsequent transactions are secure.

Syntax

startSecureTransaction(callback, scope);

Input Parameters

Parameters	Description
callback [Function] - Mandatory	If there are instances where cross site request forgery is attempted, this parameter should comprise a session/request expiry function.
scope [Integer] - Mandatory	Specifies whether this API will be valid per request or per session of the application. The possible values are as follows:0 - Request Scope: The data in the application is secure only on a per request basis.> Note: If you press the browser back button on BJS, the token is rendered invalid on the browser back request.1 - Session Scope. The data is secure for an entire user session. This is the default value.

Example

function callback() {}
voltmx.os.startSecureTransaction(callback, 1)

Return Values

This API has no return values.

Remarks

Whenever os.startsecuretransaction is invoked, a krfid for that session or request is generated internally as a hidden field. The krfid is validated for each transaction/request. If the krfid is invalid, the callback function of os.startsecuretransaction API is invoked, and the request processing fails or a message appears stating that the session has expired.

Platform Availability

Available only on Mobile Web.

voltmx.os.startSpeechRecognition
