AjaxPro配置及常用方法
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。本文绝对原创,但例子都是从网上到的,并编写测试。
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:
