copied!<p>I'm also finding the dojoKit <a href="http://dojotoolkit.org/reference-guide/1.8/dojo/xhrPost.html" rel="nofollow">xhrPost</a> documentation a bit vague. But <code>content</code> accepts name, value pairs; and I think that it's supposed to post these back as form fields.</p> <p>It appears that the xhrPost method does not automatically serialize objects to JSON strings. To be safe, I'll do that first. I'm using the <code>dojo.toJson</code> method that I found documented <a href="http://dojotoolkit.org/reference-guide/1.7/dojo/toJson.html" rel="nofollow">here</a> and are assuming is avaliable.</p> <pre><code>var xfer_data = [ {"ID":"1", "Device #":"176", "Access #":"002-20", "Address":"MH48 STEWART & CRANDON", "TP":"MF", "Curr":" ", "Last":" ", "Tdy":"8.6", "-1":"8.6", "-2":"8.6", "-3":"8.6", "-4":"8.6", "-5":"8.6", "-6":"8.6", "Wk-1":"8.6", "Wk-2":"8.6", "Wk-3":"8.6", "Wk-4":"8.6", "Alarm":" R ", "In":"14"} ]; var xfer_data_json = dojo.toJson( xfer_data ); var xhrArgs = { url: "/cgi-bin/DataExport.cgi?cmd=file", content: {data: xfer_data_json}, load: function(data) { alert('Posted!' + data); }, error: function(error) { alert('Error! ' + error); } }; dojo.xhrPost(xhrArgs); </code></pre> <p>The perl side then becomes regular CGI processing, with the need to deserialize JSON data (also untested):</p> <pre><code>#!/usr/bin/perl use warnings; use strict; use CGI; use JSON; my $cgi = CGI->new; if ($cgi->param('cmd') eq 'file') { my $data_json = $cgi->param('data'); my $devices = JSON::from_json( $data_json ); foreach my $device (@$devices) { printf ("device: id=%s access=%s address=%s\n", $device->{ID}, $device->{Access}, $device->{Address}); } } </code></pre>
