Dynamic Content Loading - HTML5 is OK, Dojo is not

Question

I've got a situation where I am loading DIV's dynamically from a server with dojo.xhrGet. All that is fine. The content comes back fine, and the DIV is inserted into the page fine. Note that in this situation, I cannot know the DIV to load prior to some other event occurring.

The problem seems to be that DIJIT widgets contained within the dynamic DIVs aren't DIJIT widgets, but run-of-the-mill HTML widgets. That is, I can work on them using "dojo.byId('widgetID')" and use standard JavaScript, but if I try "registry('widgetID')", I get an "undefined" response.

How can I get dynamically loaded and otherwise declarative DIV code to be parsed into true DIJIT widgets?

You need to use dojo/parser after your markup div has been loaded to your DOM. The function parse() will transform your HTML markup from div to a dijit widget if the markup has been decorated properly.

By the way dojo.xhrGet is Deprecated and you should use dojo/request/xhr instead.

Below and example with some pseudocode:

require(["dojo/request/xhr", "dojo/dom-construct"], function(xhr, domConstruct){
  xhr("example.json", {
    handleAs: "text" // or whatever
  }).then(function(data){
    // place your div to the dom (data is an html markup similar to this <input data-dojo-type="dijit/form/TextBox" type="text" name="dept1" />)
    var targetDom = 'targedDom';
    domConstruct.place(data, targetDom, 'replace');
    // trasform your div to a dijit widget 
    parser.parse(dojo.byId(targetDom)).then(function(){
        // after is parsed do smt here
    });

  }, function(err){
    // handle the error condition
  }, function(evt){
    // handle a progress event from the request if the browser supports XHR2
  });
});
