Add dojo widget programmatically

 We can add the dojo widget programmtically in the Javascript section. Like this:

<mce:script type="text/javascript"><!--var datepicker = dojo.widget.createWidget( "struts:StrutsDatePicker", { id: "effectiveDate", name:"location.effectiveDate", saveFormat:"rfc" });function addPicker(){var picker = dojo.byId("effectiveDate"); picker.appendChild(datepicker.domNode);}// --></mce:script>

 

or

var srcNode = document.createElement("div");srcNode.innerHTML="This is my content";var btn = dojo.widget.createWidget("Dialog", {}, srcNode);
