貌似AJAX越来越火了,作为一个WEB程序开发者要是不会这个感觉就要落伍,甚至有可能在求职的时候屡被淘汰。我也是一个WEB程序开发者,当然我也要“随波逐流”一把,不然饭碗不保啊!
之前实现AJAX使用Javascript脚本一个一个敲出来的,很繁琐。学习 Jquery之后就感觉实现AJAX并不是那么的困难了,当然除了Jquery框架外还有其它的优秀框架这里我就着重说下比较流行的Jquery。 Jquery AJAX提交表单有两种方式,一是url参数提交数据,二是form提交(和平常一样在后台可以获取到Form表单的值)。在所要提交的表单中,如果元素 很多的话建议用第二种方式进行提交,当然你要是想练练“打字水平”的话用第一种方式提交也未尝不可,相信开发者都不想费白劲吧!废话不多说了贴实例。
首先要下载Jquery、Jquery.form这两个插件,网上很多的!
一:Url参数提交数据

function checkCorpID()//检测客户编号是否可用
{
if($.trim($("#txtF_CORPID")[0].value)=="")//txtF_CORPID是客户编号输入框
{
alert("请输入客户编号!");
}
else
{
$("#checkFlag").html("正在检测");//显示提示信息
$.ajax({
type: "get",
url: "CheckCorpID.ashx",
data: "ID="+$.trim($("#txtF_CORPID")[0].value),//提交表单,相当于CheckCorpID.ashx?ID=XXX
success: function(msg){$("#checkFlag").html("");alert( msg ); } //操作成功后的操作!msg是后台传过来的值
});
}
}

context.Response.Write("该客户编号已被占用!");
}

}
}
