Dojomino :: Modifying Dojo to use Domino's OutputFormat=JSON

With Domino 7.0.2 you can get a JSON formatted response from Domino server's View URL commands, things like ?ReadDesign and ?ReadViewEntries. By adding the argument &OutputFormat=JSON the Domino server will produce JSON instead of XML. The Content-Type of this output is application/x-javascript. When integrating with Dojo 0.4.2, this is an issue as the standard AJAX type call from Dojo, dojo.io.bind(), recognizes many different Content-Types, but application/x-javascript isn't one of them.

To resolve, I chased down the 2 lines of code in the default dojo.js file and modified them to add that mimetype. It is available here. The 2 lines are line 2695 and 2791. More...

Why mod dojo.js?

You don't have to by any means. But I wanted to work with Domino's JSON output and figure out how to get Dojo to accept it. Here's some example code that will get view entries back as json:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html>

<head>

<script type="text/javascript" src="dojo.js"> </script>

<script type="text/javascript">

function initView() {

    var kw = {

        url : '/view2007/baseball.nsf/Players?ReadViewEntries&OutputFormat=JSON',

         mimetype: 'application/x-javascript',

        method: 'GET',

         load: function(type, data, evt) {

            var myData = data;

            var o = dojo.byId("output");

            o.innerHTML = data.@toplevelentries + " entries in the Players view";

};

    dojo.io.bind(kw);

dojo.addOnLoad(initView);

</script>

</head>

<body>

<div id="output"></div>

<div id="dojoDebugOutput"></div>

</body>

</html>

1 - I've not looked in detail at the 0.9 source code, but my first search reveals that the structure is quite different.

I'll dig in a little deeper and find out, but it may be a few days as I'm up to my eyeballs in a project this week.

2 - In .9 I am using this method to return JSON to the dojo.xhr function and it works great.

dojo.xhrGet( {
url: /viewName?readViewEntries&outputformat=JSON,
handleAs: "json",
handle: function(response, ioArgs) {
...
}
});

But what if you want to search a view? Have you found an easy way (or at least a logical way) to get JSON format back when searching a view? The method I am using is extremely convoluted and will be a nightmare to maintain.

Oh, what I wouldn't give for ?searchViewEntries&outputformat=JSON! Emoticon
