Configuring a JavaScript Remoting Request

Configure a remoting request by providing an object with configuration settings when you declare the remoting request.

For example, the default configuration parameters look like this:

1{ buffer: true, escape: true, timeout: 30000 }

These configuration parameters aren’t ordered, and you can omit parameters you don’t want to change from the default.

JavaScript remoting supports the following configuration parameters:

Name	Data Type	Description
buffer	Boolean	Whether to group requests executed close to each other in time into a single request. The default is `true`. JavaScript remoting optimizes requests that are executed close to each other in time and groups the calls into a single request. This buffering improve the efficiency of the overall request-and-response cycle, but sometimes it’s useful to ensure all requests execute independently.
escape	Boolean	Whether to escape the Apex method’s response. The default is `true`.
timeout	Integer	The timeout for the request, in milliseconds. The default is 30,000 (30 seconds). The maximum is 120,000 (120 seconds, or 2 minutes).

The request timeout can also be configured for all requests made by a page, by setting the timeout using the Visualforce remoting object:

1<script type="text/javascript">
2
3    Visualforce.remoting.timeout = 120000; // Set timeout at page level
4
5    function getRemoteAccount() {
6        var accountName = document.getElementById('acctSearch').value;
7
8        // This remoting call will use the page's timeout value
9        Visualforce.remoting.Manager.invokeAction(
10            '{!$RemoteAction.AccountRemoter.getAccount}',
11            accountName, 
12            handleResult
13        );
14    }
15
16    function handleResult(result, event) { ... }
17</script>

Override a page-level timeout configuration on a per-request basis by setting the timeout in the configuration object for that request, as described above.
