spring mvc Controller与jquery Form表单提交代码demo

1.JSP表单

<%
String basePath = request.getScheme() + "://" + request.getServerName() +":"+ request.getServerPort() + request.getContextPath() + "/";
%>
<script language="javascript" type="text/javascript" src="<%=basePath %>js/datePicker/WdatePicker.js"></script>

<form id="insForm" action="car/updateInsuranceInfo" style="border:none;" method="post" > <!-- onsubmit="return checkIns();" -->
    <input name="carNo" type="hidden" value="${car.carNo}"/>
    <table>
        <tr>
            <td>交强险投保公司：<input id="insCorp" name="insCorp" type="text" value="${car.insCorp}"></td>
            <td>交强险保单号：<input id="insNo" name="insNo" type="text" value="${car.insNo}"></td>
            <td>交强险被保险人：<input id="insInsured" name="insInsured" type="text" value="${car.insInsured}"></td>
            <td>交强险到期日期：<input id="insExpire" name="insExpire" type="text" value="${car.insExpire}" class="Wdate" onClick="WdatePicker({skin:'whyGreen'})"></td>
            <td align="center"><input type="button" value="更新交强险信息" onclick="checkIns();"/></td>
        </tr>
    </table>
</form>

2.javascript代码(提交整个表单或单个参数值，如 data:"carNo=" + carNo +  "&insCorp=" + insCorp + "&insNo=" + insNo + "&insInsured=" + insInsured + "&insExpire=" + insExpire,,  或 var data = {"carNo":carNo,"insCorp":insCorp,"insNo":insNo,"insInsured":insInsured,"insExpire":insExpire};)

function checkIns(){
    //验证非空
        var flag = false;
    $("#insForm input[type='text']").each(function(){
        if($(this).val()=='') {
            //alert('第'+($(this).index()+1)+'个文本框为空');
            layer.alert("请完善交强险信息!",5);
            flag = true;
        }
    });
    if(flag){
        return;
    }else{
        //ajax提交
        $.ajax({
            url:"car/updateInsuranceInfo", 
            data:$('#insForm').serialize(), // 从表单中获取数据
            type:"POST", 
            error:function(xmlHttpRequest, error) { // 设置表单提交出错
                alert("操作失败，请联系系统管理员或稍后再试！"+error);
            },
            success:function(resData) {
                if(resData != 0){
                    layer.alert("更新交强险成功！",1);
                }else{
                    layer.alert("更新交强险失败!",3);
                }
            }
        });
    }

}

data:$('#insForm').serialize(), // 从表单中获取数据

3.controller

@Controller
@RequestMapping("/car/")
public class CarController {
        @ResponseBody
    @RequestMapping(value="/updateInsuranceInfo",method=RequestMethod.POST)
    public Integer updateInsuranceInfo(@RequestParam Map<String,Object> data, HttpServletRequest request){
        if(carService.updateInsuranceInfo(data) != 0){
            return 1;
        }
        return 0;
    }
    
}    

@RequestParam Map<String,Object> data，也可以写成model对象方式(InsuranceInfoModel model,)，或需要获取的参数方式(@RequestParam String insCorp, @RequestParam String insNo, @RequestParam String insInsured, @RequestParam String insExpire)。

4.sqlmap

<update id="updateInsuranceInfo">
        UPDATE car SET insurance_corp=#{insCorp}, insurance_no=#{insNo},insurance_insured=#{insInsured},insurance_expire=#{insExpire} WHERE reg_no=#{carNo}
    </update>
