AjaxPro使用方法

无意中看到同事用AjaxPro用,看到很不错,特长是前后台传输数据特别方便。

最好的教材就是拿到就可以用,方便大家。

以前数据传输用FORM提交,或者在前台用JASON拼接然后通过AJAX方式提交。总之要写好多代码,很不方便。要么页面刷新,要么总是写一件重复代码。

AjaxPro的方便之处就是前台不需要写太多的代码,可以直接跟后台方法进行访问,中间用数据JASON数据传输这一切她都已经帮你做了。网上找了几个教程都感觉不错。现在我把她从配置到例子整理下分享给大家。

一、配置AjaxPro:

1. 下载AjaxPro.2.dll并添加到工程里,如图:

2. 在web.config中添加注册信息

3. 准备测试,在后台Page_Load注册下,如下图:

这样就配置好了。
二、这里只举下个例子,从后台得到字符串,其他情况我会把代码全部加上,相信大家都能看得懂。
后台代码:

前台代码:

也可以不加回调函数,如果不加的话就是异步调用,否则就是同步调用。两者区别就不用说了吧。直接加个BUTTON去调用TestString就可以了。
显示alert message 如下:

下面附上在开发过程中遇到的几种常见情况,欢迎大家扩充:
