dojox.grid.DataGrid populated from Servlet
- by jeff porter
I'd like to hava a Dojo dojox.grid.DataGrid with its data from a servlet.
Problem: The data returned from the servlet does not get displayed, just the message "Sorry, an error has occured".
If I just place the JSON string into the HTML, it works. ARRRRGGH.
Can anyone please help me!
Thanks
Jeff Porter
Servlet code...
public void doGet(HttpServletRequest req, HttpServletResponse resp) {
res.setContentType("json");
PrintWriter pw = new PrintWriter(res.getOutputStream());
if (response != null) pw.println("[{'batchId':'2001','batchRef':'146'}]");
pw.close();
}
HtmL code...
<div id="gridDD" dojoType="dojox.grid.DataGrid"
jsId="gridDD" style="height: 600x; width: 100%;"
store="ddInfo" structure="layoutHtmlTableDDDeltaSets">
</div>
var rawdataDDInfo = ""; // empty at start
ddInfo = new dojo.data.ItemFileWriteStore({
data: {
identifier: 'batchId',
label: 'batchId',
items: rawdataDDInfo
}
});
<script>
function doSelectBatchsAfterDate() {
var xhrArgs = {
url: "../secure/jsonServlet",
handleAs: "json",
preventCache: true,
load: function(data) {
var xx =dojo.toJson(data);
var ddInfoX = new dojo.data.ItemFileWriteStore({data: xx});
dijit.byId('gridDD').setStore(ddInfoX);
},
error: function(error) {
alert("error:" + error);
}
}
//Call the asynchronous xhrGet
var deferred = dojo.xhrGet(xhrArgs);
}
</script>
<img src="go.gif" onclick="doSelectBatchsAfterDate();"/>
