clarify the loading process of the Dojo Widget.
After tracking and debugging, I have a general understanding of the Dojo widgets: first, load the JavaScript file that is currently needed, and then parse the entire html page. There are three ways to use widgets on pages: one is to add some attributes that can be parsed by dojo on html elements, such

Label: style HTTP Io ar OS SP Div on Art Consider this example: When a page is dynamically created, multiple listitems are generated using new listtem (), and each listitem generates a button. Assuming that you want to bind a click event to each button, it is easier to use dojo. query to obtain these buttons than compile. In this case, I encountered a problem. In the create button loop statements, I defined id = "somebtn" for each button ". Then t
By studying the first six parts of this series, you've got a good idea of the power of Dojo. But sometimes some of the dojo's features do not fully meet the actual requirements, and you need to extend the dojo, for example, to extend the Widget so that it is more responsive to the requirements of the project. This article will detail the object-oriented features of dojo
Dojo BASICS (ii) read data from the server this example follows the content in "dojo basics"
First, create a new file named
Response.txt, content:Welcome to the Dojo Hello World Tutorial
Replace section 2 with the following code:
Label: dojo dijit
Dijit/form/textbox: A basic text box
Dijit/form/simpletextarea: A large number of text input, a basic textarea
Dijit/form/textarea: One extended dijit/form/simpletextarea dynamically increases or reduces its height
Dijit/form/numbertextboxOrDijit/form/numberspinner: The input is a number. Make sure to enter a text box. dijit/form/numberspinner provides a button to extend dijit/form/numbertextbox to gradually change the value.

Today, various sites using AJAX technology implement the drag and Drop (drag) effect, using the Dojo framework can be easily implemented, compared to other frameworks, less code, and browser compatibility support better.
First look at the effect, the following is

How to use a widget in Dojo
Notes for use with Asp.net
Programming for winform in vs2005, with the splitcontainer control available; webform does not have such a thing. I asked Mr. Zhao, and he said, "Try the splitcontainer of dojo." So I checked n more information and finally got it done for one day. Next I will summarize my experiences. : How to use a widget in

Common techniques for solving Dojo performance problems
Customizing and compressing Dojo
Typically, a complete dojo library will be around 2M, which includes various JS tool methods provided by Dojo, core IO framework, Dragdrop support, rich widgets and their cor
In the dojo. DND package, Dojo provides support for the drag and drop effects of page elements. The key classes used to achieve the drag effect are as follows.
Next, let's take a look at the usage of these four classes.
First, define two divs and a list:
Drag Module 1
Drag module 2

Mobile. tabbar (a class that is not included by default in dojox. Mobile ). Then, the tweetview namespace is added to the prefixes array.
Execute build
Let's switch to the command line and use the build profile above to package our widgets:
./Build. Sh single WebKit
After the build is complete, you can view the result in

When type = "LOAD", the three parameters are the same as load (). When type = "error", data indicates errorobject in error, the event is invalid. The following example uses handle () (from the official website ):1 dojo. Io. BIND ({
