1.如果不用ajax的form提交，就必须把表单的每一条数据进行获取，并提交给action进行处理。这样做比较麻烦，现在用了jQuery的easyui，使用封装好的ajax的form提交。脚本代码如下：
//提交表单
function sysusersave(){
if($.formValidator.pageIsValid()){//校验表单输入信息是否合法
//使用jquery的ajax from提交，指定from的id和回调方法，提交的url使用提from中的action，参数为空，传递JSON字符串（去掉也不报错）
jquerySubByFId('sysusereditform',sysusersave_callback,null,"json");
}
}
//from提交的回调方法,data是提交的返回的数据
function sysusersave_callback(data){
message_alert(data);
}
注意：上面的回调函数，是action处理后，返回JSON的数据传给了参数data。
上面函数具体的实现（没有封装的代码）：要传递四个参数
/*
*form提交(post方式)
*
*formId form Id
*callbackfn 回调函数名(要求函数必须有参数且不能多与两个,一个参数时参数为响应文本,两个参数时第一个参数为响应文本)
*param 回调函数参数(如果为null,那么调用一个参数的回调函数,否则调用两个参数的回调函数)
*/
function jquerySubByFId(formId,callbackFn,param,dataType){
var formObj = jQuery("#" + formId);
var options = {
dataType: ("undefined"!=dataType && null!=dataType)?dataType:"json",
success: function(responseText) {
if(param === null){
callbackFn(responseText);
}else{
callbackFn(responseText,param);
}
}
};
formObj.ajaxSubmit(options);
}
2.校验表单输入信息是否合法：使用的是jQuery easyui的内置校验器，如下 ，列举出来的对用户账号进行的校验：
$(function (){
/******表单校验*************/
$.formValidator.initConfig({
formID : "sysusereditform",
theme : "Default",
onError : function(msg, obj, errorlist) {
//alert(msg);
}
});
//用户账号
$("#sysuser_userid").formValidator({
onShow : "",
onCorrect:" "
}).inputValidator({
min : 1,
max : 20,
onError : "请输入用户账号(最长10个字符)"
});
});
校验的具体方法：
//====================================================================================================
// [插件名称] jQuery formValidator
//----------------------------------------------------------------------------------------------------
// [描 述] jQuery formValidator表单验证插件，它是基于jQuery类库，实现了js脚本于页面的分离。对一个表
// 单对象，你只需要写一行代码就可以轻松实现20种以上的脚本控制。现支持一个表单元素累加很多种
// 校验方式,采用配置信息的思想，而不是把信息写在表单元素上，能比较完美的实现ajax请求。

使用这些已经写好的方法来处理表单数据，要导入对应的js库
以下HTML的代码是把项目中应用到的js库引入到程序中：
