- <div class="description">
- An implementation of Roo.data.DataProxy that reads a data object from a URL which may be in a domain<br/>other than the originating domain of the running page.<br><br><br/><p><br/><em>Note that if you are retrieving data from a page that is in a domain that is NOT the same as the originating domain<br/>of the running page, you must use this class, rather than DataProxy.</em><br><br><br/><p><br/>The content passed back from a server resource requested by a ScriptTagProxy is executable JavaScript<br/>source code that is used as the source inside a <script> tag.<br><br><br/><p><br/>In order for the browser to process the returned data, the server must wrap the data object<br/>with a call to a callback function, the name of which is passed as a parameter by the ScriptTagProxy.<br/>Below is a Java example for a servlet which returns data for either a ScriptTagProxy, or an HttpProxy<br/>depending on whether the callback name was passed:<br/><p><br/><pre><code><br/>boolean scriptTag = false;<br/>String cb = request.getParameter("callback");<br/>if (cb != null) {<br/> scriptTag = true;<br/> response.setContentType("text/javascript");<br/>} else {<br/> response.setContentType("application/x-json");<br/>}<br/>Writer out = response.getWriter();<br/>if (scriptTag) {<br/> out.write(cb + "(");<br/>}<br/>out.print(dataBlock.toJsonString());<br/>if (scriptTag) {<br/> out.write(");");<br/>}<br/></pre></code>
