How to check if the Dojo dialog is loaded?

Question

I run a function that should close the Dojo dialog if it is loaded. How to check if the Dojo dialog works? I use pure JavaScript and check by id if it is undefined?

if (dijit.byId("blah") !== undefined) { 
     destroyRecursive dijit;
}

Or I use a property of a dialog object, for example:

isFocusable method
isLoaded property

Answer 1

The dialog provides two properties that you can check: isLoadedand open. Digging through the code, you will find the following descriptions:

• open: True if a dialog is currently displayed.
• isLoaded: , ContentPane , ( href ), attr ('content',...)/attr ('href',...) False, , ContentPane href.

, :

var dialog = dijit.byId("blah");
if( dialog.open ) {
    dialog.destroy();
}
