jquery.post用法详解编程语言

callback:发送成功时回调函数。

type:返回内容格式，xml, html, script, json, text, _default。

$.post(admin/HhCheckVote.do?ids= + ${ids}, {}, function(flag) { 

 if(flag.isVote=="true"){ 

 document.getElementById("jvForm").action="admin/HhArticleVoteCommit.do"; 

 document.getElementById("jvForm").submit(); 

 }else{ 

 alert("您已经投过票！"); 

 });

struts.xml中action配置为：

 action name="HhCheckVote" method="checkVote" 

 result type="json" /result 

 /action 

Action

private String isVote; 

public String getIsVote() { 

 return isVote; 

 public void setIsVote(String isVote) { 

 this.isVote = isVote; 

public String checkVote(){ 

 try { 

 List Map String,Object list = aloneIMP.checkVote(ids,getCurrentUser()).search().getResultList(); 

 if(list.size()==0){ 

 isVote = "true"; 

 }else{ 

 isVote = "false"; 

 } catch (SQLException e) { 

 // TODO Auto-generated catch block 

 e.printStackTrace(); 

 return SUCCESS; 

 }
