Overview
The Memory Module is used to to retrieve the current available memory and send notifications when memory drops below a user-defined threshold.
Enabling the API
In order to use this API you must include reference to the following JavaScript file that is included with the Enterprise Browser installation:
- elements.js
Note - this file either needs to be on the device in a relative folder from where your HTML page is, or it must be copied to your web server appropriately.
<script type="text/javascript" charset="utf-8" src="elements.js"></script>;API Usage
This API does not use the EB namespace. It is simply referenced using the API name:
memory.getMemoryStats();Events
To handle events, you assign a string value to the event name that represents a function name or javascript statement to execute.
memoryEvent
The memoryEvent event is triggered when the available Memory drops below the set value.
Callback Parameters
- totalMemory - The total memory in the device, specified in KB.
- availMemory - The available memory in the device, specified in KB
Usage
memory.memoryEvent = "url('JavaScript:getMemory(%json);')";
function getMemory(params)
{
alert("Total Memory: " + params.totalMemory + "KB, Avail Memory: " + params.availMemory + "KB");
memory.lowMemThreshold = params.totalMemory / 10;
memory.memoryEvent = "onLowMemory(%json);";
}
function onLowMemory(params)
{
alert("The device is running low on memory, only " + params.availMemory + "KB is left on the device");
}Methods
getMemoryStats()
This returns the current status of the device such as total memory and available memory via memoryEvent definition.
