that only the content that needs to be updated is returned. Instead of returning other content that already appears on the page, the amount of data returned from the server is less than it used to be. AJAX-enabled Web applications take a long time to load initially, but after loading, their performance is much better than the original Web application. This article describes some of the changes that XMLHttpRequest objects have brought to web development, which are important reasons for the popu

Email: longsu2010 at yeah dot netAnyone who knows John Resig's JavaScript Micro-Templating knows its simplicity and the amount of code to be implemented is small.In the dojo/string module, dojo provides a very concise template replacement function substitute.Here is an example. Require (["dojo/string"], function (string ){Var html = "File '$ {name}' is not found

We recommend that you reference the dojo learning notes. before js, it is best to declare the djConfig object to load the dojo. js can get the set value. Although dojo supports post-loading setting after version 0.3 and later, we strongly recommend that you use the code to declare djConfig as the first script: A complete djConfig object is defined as follows (val

Two kinds of drag-and-drop methods supported by Dojo Before you start trying to understand how to implement the Dojo drag-and-drop effect, you first have to be clear that dragging has two distinct performance effects. The first performance effect is the icon dragged to where, it will be placed directly where, the drag effect is the icon is exactly the same drag-and-drop action, and each drag-and-drop moti

Dojo BASICS (3) send data to the server and send data to the server using get and post. First, replace the html code in the body Hello World! Enter the name:If you do not enter data, how can you submit the data. GetWe only need:Function helloPressed (){Dojo. io. bind ({Url: 'response.txt ',Handler: helloCallback});}Replace: function helloPressed() { dojo.io.bind({ url: 'HelloWorld

Dijit Introduction Starting with Dojo 0.9, dojo separates widgets from Dojo's core packages to form Dijit. Dojo adds a number of members to the widget family in Dijit, enhancing the widget's strength while also speeding up its load on the page. To improve the Widget's appearance, Dijit offers several sets of style themes, such as the default-bound style theme T

Hitch ()Hitch () is a function that executes a given execution function at the given top and bottom. Hitch allows you to control how a function executes and often works in an asynchronous operation.We often write code like this: (blogger: This code intends to execute the "processevent" definition at this point when the "click" event is triggered.) ）1 function (ON) {2 var function (e) {3 this. Something = "Else"; 4 }; 5 On (Something, "click", processevent); 6 }); It is an err

1. Subject Dijit has four themes to choose from: Claro, tundra, Soria, and nihilo. To use dijit theme, you also need to introduce the CSS file of the theme and add the CSS style name to the body element on your page. Note: You can use Div block-level elements to restrict dijit themes to only a small part of a page. If CSS is not set on the body, then any pop-up parts (for example, use pop-up dijit/form/combobutton dijit/form/dropdownbutton, dijit/form/select) create and place the pop-up Dom str

In section 2, we introduced a simple Dom operation method. Next we should go to the traditional Ajax project-XMLHttpRequest. When using XMLHttpRequest, you need to pay attention to the encoding problem. What should I do if I want to bind dojo to UTF-8 by default? It's easy. You just need to modify the label when dojo. JS is introduced: Next, we will use an example to illustrate how to use XMLHttpRequest i

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
