ajax以java封裝的model對(duì)象傳值方式

前臺(tái)web代碼

function update_save(frId){
    debugger;
    var json={};//json對(duì)象里面的key完全包含于封裝的Bridge對(duì)象的屬性
    $.each($('#'+frId).serializeArray(),function(index,item){
        var  brigeKey =  this['name']
        if(brigeKey.substring(0,4) == 'unst') return true;
        json[this['name']]=this['value'];
     })
     var bridge = JSON.stringify(json);
    $.ajax({
        url : 'bridge_modify.fdo',
        type : "POST",
        data :{"brgeJStr":bridge},
        dataType : 'json',
        success : function(returndate, status) {
            debugger;
            dateObj = eval('(' + returndate + ')');
            var flag = dateObj.flag;
            var msg  = dateObj.msg;
            alert('modifyPan',' 修改數(shù)據(jù)',msg);
        }
});
}

java代碼

2.1 java的Bridge 模版

/*

橋梁對(duì)象
*/
public class TBridge {
 private Long bridgeid;//主鍵

 private String unst_fieldid;//查詢排序
 private String unst_geoxy;//空間坐標(biāo)

 private String deptkey;//管理單位代碼
 private String departmentkeys;//管理單位代碼
 //............省略get，set方法
}

2.2 java的對(duì)應(yīng)的Action 模版

public class TBridgeAction extends BaseActon implements Preparable{
 private static final long serialVersionUID = 8309913025508352320L;
 private static Logger log = Logger.getLogger(TBridgeAction.class);

 private String  brgeJStr;

 public String getBrgeJStr() {
 return brgeJStr;
 } public void setBrgeJStr(String brgeJStr) {
 this.brgeJStr = brgeJStr;
 }
 public String modify() throws Exception{
 JSONObject jo = new JSONObject();


 try{
     //把前天傳過來的json字符串對(duì)象轉(zhuǎn)化成json對(duì)象
     JSONObject jsonObject=JSONObject.fromObject(brgeJStr);
     //把前天傳過來的json字符串對(duì)象轉(zhuǎn)化成json對(duì)象后，再轉(zhuǎn)化為java封裝對(duì)象
     TBridge bridge=(TBridge)JSONObject.toBean(jsonObject, TBridge.class);


 }catch(Exception e){
     log.error("修改橋梁信息出錯(cuò)，錯(cuò)誤信息："+e.getMessage());
 }
 return "success";
 } ｝
