我想了解如何使用JSON和在这个过程中,我试图从Struts2的行动JSON响应并显示报警响应。对于这个,我使用Ajax POST在JavaScript如下:
函数checkButtonClick(ID){
VAR btnSave ='saveAttendees';
VAR atNameList = $('#attName'+ id)的.VAL();
VAR ptNameList = $('#postName'+ id)的.VAL();
变种AID = $('#at_id'+ id)的.VAL();
警报(这里);
VAR ARR = {buttonName:btnSave,
attendeesNameList:atNameList,
attendeesPostList:ptNameList,
hidden_At_id:援助
};
$阿贾克斯({
数据:ARR,
键入:POST,
数据类型:JSON,
网址:meeting_record_form
成功:函数(结果){
警报(result.myMsg);
},
错误:函数(结果){
警报(错误);
}
});
}
我的动作类包含一个字符串
字段,我想在警报为JSON响应显示。但是,我发现问题这样做。我在想什么或者做错了吗?
我的动作类如下:
私人字符串myMsg;
公共字符串getMyMsg(){
返回myMsg;
}
公共无效setMyMsg(字符串myMsg){
this.myMsg = myMsg;
}
私人字符串updateAttendeesRecord(){
meetingRecordService.updateAttendeesRecord(attendeesListMethod(),meeting_record);
setMyMsg(更新成功!);
返回成功;
}
的struts.xml
文件:
<包名称=默认扩展=支柱默认,JSON-默认>
<结果类型>
<结果类型名称=JSON级=org.apache.struts2.json.JSONResult/>
< /结果类型>
<拦截>

< /拦截>
<作用NAME =meeting_record_form级=com.task.action.MeetingRecordAction方法=updateAttendeesRecord>
<结果名称=成功TYPE =json的/>
< /作用>

我通过JSON结果将myMsg解决我的问题。感谢所有帮助
I am trying to understand how to use JSON and in the process I'm trying to get a JSON response from Struts2 action and display an alert for the response. For this I'm using Ajax POST in JavaScript as follows:
function checkButtonClick(id){
var btnSave = 'saveAttendees';
var atNameList = $('#attName'+id).val();
var ptNameList = $('#postName'+id).val();
var aId = $('#at_id'+id).val();
alert("here");
var arr = {buttonName: btnSave,
attendeesNameList: atNameList,
attendeesPostList: ptNameList,
hidden_At_id: aId
};
$.ajax({
data: arr,
type: 'POST',
dataType: 'json',
url:"meeting_record_form",
success:function(result){
alert(result.myMsg);
},
error:function(result){
alert("error");
}
});
}
My action class contains a String
field that I'm trying to display in alert as JSON response. But I'm finding problem doing this. What am I missing or doing wrong?
My action class is as follows:
private String myMsg;
public String getMyMsg() {
return myMsg;
}
public void setMyMsg(String myMsg) {
this.myMsg = myMsg;
}
private String updateAttendeesRecord() {
meetingRecordService.updateAttendeesRecord(attendeesListMethod(), meeting_record);
setMyMsg("Update Successful!");
return SUCCESS;
}
struts.xml
file:
<package name="default" extends="struts-default, json-default">
<result-types>
<result-type name="json" class="org.apache.struts2.json.JSONResult" />
</result-types>
<interceptors>
<interceptor name="json" class="org.apache.struts2.json.JSONInterceptor" />
</interceptors>
<action name="meeting_record_form" class="com.task.action.MeetingRecordAction" method="updateAttendeesRecord">
<result name="success" type="json" />
</action>
</package>
My pom.xml
:
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-json-plugin</artifactId>
<version>2.3.15</version>
</dependency>
