ajax传对象到action

我的系统是用struts+spring把js传过来的变量直接通过spring注入的方式注入到action中去的。

如果一个方法传的变量比较多，这样就会造成比较混乱的感觉，所以需要用对象把这些变量封装起来，通过ajax来传递。根据个人的开发测试：具体操作如下：

第一种方式：

1、js中

function closeWinForm(url,model){
debugger
var wkfParam = transfObject(url);
// var wkfParam = JSON.stringify(str);
var parms = url.split(/\?/);
// var wkfParam={"wkfParam.wkfModeNo":"111","wkfParam.appNo":"222"};
$.ajax({
type: "post",
url: parms[0],
async:false,
data:wkfParam,
dataType:"json",
success: function(data) {
if(data["flag"]=="success"){
alert("提交成功！", 1);
if(model == 1){
window.top.cloesBigForm(window,"","iframepage");
}else if(model == 2){
window.location.href = lk;
}
}else if(data["flag"]=="error"){
alert("提交失败！",0);
}
}
});
}

function transfObject(urlstr){
var parms = urlstr.split(/\?/)[1].split(/&/);
var wkfParam = {};
for(var i=0;i<parms.length;i++){
var keyvalue = parms[i].split(/=/);
if(keyvalue[0]=="taskId"){
wkfParam["wkfParam.taskId"] =keyvalue[1];
}
if(keyvalue[0]=="transition"){
wkfParam["wkfParam.transition"] = keyvalue[1];
}
if(keyvalue[0]=="opinionType"){
wkfParam["wkfParam.opinionType"] = keyvalue[1];
}
if(keyvalue[0]=="approvalOpinion"){
wkfParam["wkfParam.approvalOpinion"] = keyvalue[1];
}
if(keyvalue[0]=="nextUser"){
wkfParam["wkfParam.nextUser"] = keyvalue[1];
}
if(keyvalue[0]=="activityType"){
wkfParam["wkfParam.activityType"] = keyvalue[1];
}
if(keyvalue[0]=="isAssignNext"){
wkfParam["wkfParam.isAssignNext"] = keyvalue[1];
}
if(keyvalue[0]=="appNo"){
wkfParam["wkfParam.appNo"] = keyvalue[1];
}
if(keyvalue[0]=="wkfVpNo"){
wkfParam["wkfParam.wkfVpNo"] = keyvalue[1];
}
if(keyvalue[0]=="wkfModeNo"){
wkfParam["wkfParam.wkfModeNo"] = keyvalue[1];
}
}
return wkfParam;
}

注意红线标注的地方，一定要这样写，属性是对象.属性的形式，这样传到后台才能正确接收，

2、action

public class TbProFilterRecordAction extends BaseFormBean{ 
    private WkfParam wkfParam;

   public WkfParam getWkfParam() {
        return wkfParam;
    }


    public void setWkfParam(WkfParam wkfParam) {
        this.wkfParam = wkfParam;
    }

}

后台通过注入wkfParam这个参数来接收即可。

第二种方式：通过url

function transfUrl(urlstr){
var parms = urlstr.split(/\?/)[1].split(/&/);
var url = urlstr.split(/\?/)[0] + "?1=1";
var wkfParam = {};
for(var i=0;i<parms.length;i++){
var keyvalue = parms[i].split(/=/);
if(keyvalue[0]=="taskId"){
url += "&wkfParam.taskId=" + keyvalue[1];
}
if(keyvalue[0]=="transition"){
url += "&wkfParam.transition=" + keyvalue[1];
}
if(keyvalue[0]=="opinionType"){
url += "&wkfParam.opinionType=" + keyvalue[1];
}
if(keyvalue[0]=="approvalOpinion"){
url += "&wkfParam.approvalOpinion=" + keyvalue[1];
}
if(keyvalue[0]=="nextUser"){
url += "&wkfParam.nextUser=" + keyvalue[1];
}
if(keyvalue[0]=="activityType"){
url += "&wkfParam.activityType=" + keyvalue[1];
}
if(keyvalue[0]=="isAssignNext"){
url += "&wkfParam.isAssignNext=" + keyvalue[1];
}
if(keyvalue[0]=="appNo"){
url += "&wkfParam.appNo=" + keyvalue[1];
}
if(keyvalue[0]=="wkfVpNo"){
url += "&wkfParam.wkfVpNo=" + keyvalue[1];
}
if(keyvalue[0]=="wkfModeNo"){
url += "&wkfParam.wkfModeNo=" + keyvalue[1];
}
}
return url;
}

此方法不用data去传值，直接通过url，action依然用spring注入方式。
