152 <p><strong>Return value:</strong></p> |
|
153 <p>If the call succeeds, the <code>getServiceObject</code> method |
|
154 returns a service object; otherwise it returns <code>undefined</code>.</p> |
|
155 <p><strong>Remarks:</strong></p> |
|
156 <ul> |
|
157 <li><p>The <code>getServiceObject</code> method is a factory |
|
158 method found on the <code>device</code> object.</p></li> |
|
159 <li><p>To ensure backward compatibility, always check in your JavaScript |
|
160 code that the <code>device</code> object exists before calling the <code>getServiceObject</code> method. |
|
161 For example:</p> |
|
162 |
|
163 <pre class="codeblock" id="GUID-B43A804D-CBB6-44E4-9514-E1982EA50507">if (device != "undefined") |
