AJAX/VS2005-ajax+vs2005新特色
关注ajax(Asynchronous JavaScript and XML) 好长时间了,现在vs2005也正式发布了
vs2005上的新特性无刷新技术是用到了ajax ,ajax 看来要在vs2005上放光异彩了.
看看官方的介绍
AJAX (Asynchronous JavaScript and XML) describes a cross-platform, client-centric approach to developing Web applications. In AJAX, developers use client scripts to make asynchronous calls to Web server applications using an XML-based protocol. The new ASP.NET technology code-named "Atlas" is a package of Microsoft technologies that applies and extends the AJAX approach. This topic describes the Web application development issues that AJAX addresses, explains the basic concepts of AJAX, and introduces ASP.NET "Atlas" as a significant evolution and enhancement of the AJAX approach.
无刷新应用很广泛,就不多说了
贴个小代码:
function up_load(msg)
{
if (window.XMLHttpRequest)
{
req = new XMLHttpRequest();
}
else if (window.ActiveXObject)
{
req = new ActiveXObject("Microsoft.XMLHTTP");
}
req.onreadystatechange = processChech;
req.open( "post", "up_load_checktable.aspx",false);
req.send();
}
function processChech()
{
if (req.readyState == 4)
{
var content = document.getElementById("pub");
if (req.status == 200)
{
content.innerHTML = req.responseText;
}
else
{
content.innnerText = "操作失败！";
}
}
}
以上是个简单的应用,其实vs2005 AJAX就是封装了这些东西,成了一个框架,可以调用
可以应用在web services ,按钮的事件上,form 的提交上等等
