dojo aspect not defined, dont understand why

问题:

I want to update from dojo 1.7 to 1.8.3 so I have to replace the dojo.connect command.

switch:

< div id="universalPushSwitch" data-dojo-type="dojox.mobile.Switch" style="float:right" class="mblSwRoundShape1"></div>

Now I have:

dojo.require("dijit/registry");
dojo.require("dojo/ready");
dojo.require("dojox/mobile/ListItem");
dojo.require("dojo/aspect");

dojo.ready(function(){
  dojo.aspect.after(dijit.registry.byId("universalPushSwitch"), "onStateChanged", 
        function(newState){
        alert(newState);
    }
)});

Firebug says: "aspect is not defined"

PS: I know I don't use the new AMD loader. This is an old project and I am also new to all the dojo stuff. A simple translate from dojo.require("x");dojo.require("y"); to require(["x","y"], function (x,y){...} doesn't work for me so there is still the old style require.

回答1:

Try using:

dojo.aspect.after(...);

instead of

aspect.after(...);

And do not stop at the next function ! :-)

If that doesn't work at once, try loading aspect the global way (with a dot, not a slash):

dojo.require("dojo.aspect");

It also could be possible, that the old dojo is not compatible with "/" and that it only works with dots !

Edit

Here is a working fiddle based on your fiddle:

http://jsfiddle.net/9Xdv2/

The main problem with your code was that you did not parse the html. dojo parser converts some specific html to "dojo javascript objects" ! You use that kind of html a lot ! You should have done a:

dojox.mobile.parser.parse();

Everything is in the jsfiddle !

Since you are using dojo 1.8.3 and have been using dojo 1.7, why don't you use the AMD syntax instead of the pre-1.7 ? You would do something like :

<div id="universalPushSwitch" data-dojo-type="dojox/mobile/Switch" style="float:right" class="mblSwRoundShape1"></div>

And in your js :

require(["dijit/registry",
         "dojox/mobile/ListItem",
         "dojo/aspect",
         "dojo/parser",
         "dojo/domReady!"
         ], function(registry, ListItem, aspect, parser){

    parser.parse().then(function(instances){
        aspect.after(registry.byId("universalPushSwitch"), "onStateChanged", 
           function(newState){
               alert(newState);
           });
    });
});
