What the difference between dojo.byId and dijit.byId?

问题

Each time am trying the get the value of an element in my page, I have an error as is undefined: I have tried dijit.byId('myid').innerHTML('loading...');

I get an error but when i do the same using jquery, it works $­('#myid').html('loading ...')

And what is the equivalent of this $('#myid').html() in dojo? Thanks for any advise

回答1:

dijit.byId returns a dijit object by some id.

dojo.byId is the equivalent of $(). To get/set it's HTML, use

dojo.byId("my_id").innerHTML
dojo.byId("my_id").innerHTML = some_text`

Note that dojo.byId is just a wrapper around document.getElementById, so you can use all the basic functions.

回答2:

dijit.byId("my_id") ----> returns the widget associated with the domNode.
dojo.byId("my_id") -----> returns the domNode itself.

To access the domNode using dijit:

dijit.byId("my_id").domNode.innerHTML
