Step one introduce JS file
Copy Code code as follows:
<script language= "javascript1.2" src= "<s:url value="/js/jquery.js "includeparams=" false "/>" ></ Script>
<script language= "javascript1.2" src= "<s:url value="/js/dictionary.js "includeparams=" false "/>" ></ Script>
Step two public js file Dictionary.js
Copy Code code as follows:

* Function: Public method initialization
* Detailed: Common method initialization

/*1. Loss of focus verification ↓↓↓*/
$ ("#code"). blur (callback);//1.code is the control ID 2 for the unique flag you want to validate. You must have a control behind your control that receives the error message
/*2. Validate ↓↓↓*/at time of submission
$ ("#submit"). Click (callback)//The Submit button ID of your page
});
/**

var slef=$ ("#code");
var code=slef.val ();
var submit=$ ("#submit");
var flag=$ ("#flag"). Val ();
if (null==code| | "" ==code) {
Slef.next (). html ("Download package ID cannot be empty!");
Submit.attr ("Disabled", true);
Return
}else{
if (!code.match ("^\\w+$")) {

return;
}
Slef.next (). HTML ("*");
}
$.ajax ({

}else{
Submit.attr ("Disabled", true);
Return
}
}
},
Error:function () {
Alert (' Verify information error ');
}
});
}
Step three page section
Copy Code code as follows:
<s:hidden id= "Flag" value= "3"/> <!-flag what type of flag->
<tr>
<TD width= "40%" height= "class=" "ADDTABLETD1" > Download logo:</td>
<TD width= "60%" height= "class=" Addtabletd2 ><div "left" >
<s:textfield id= "code" name= "Yhaoportalsdownbean.downflag" cssclass= "Textfrom" cssstyle= "width:150px"; Maxlength= "/>"
<font id= "Codeinfo" color= "Red" >*</font>
</div></td>
</tr>
step four method in action
Copy Code code as follows:
/**
*
* @author Zhuangzi
* @class com.hzdracom.action.YhaoPortalsDictionaryAction
* @method checkcodeonly
* @Directions Validation Unique identification common method
* @date 2013-3-21 a.m. 10:09:04 void
*/
public void Checkcodeonly () {
String json= "";
try{
JSON = string.valueof (yhaodictionaryservice.checkcodeonly (bean));
Json=json.tojsonstring (JSON);
System.out.println ("json==" +json);
HttpServletResponse Response=servletactioncontext.getresponse ();
Response.setcontenttype ("text/html");
Response.setcharacterencoding ("Utf-8");
PrintWriter out;
out = Response.getwriter ();
OUT.PRINTLN (JSON);
Out.flush ();
Out.close ();
}catch (Exception e) {
E.printstacktrace ();
}
}
step five method in DAO
Copy Code code as follows:
<pre Class=java name= "code" > public int checkcodeonly (Dictionarybean bean) throws Dataaccessexception,exception {
object[] Sqlparams = new Object[4];
int index = 0;
String sql= "";
/* Verify that the page flag is unique * *
if (Bean.getflag (). Equals ("1")) {
sql = "SELECT COUNT (1) from yhao_portals_page where Page_flag =?";
Sqlparams[index]=bean.getcode ();
index++;

/* Verify that the type of log ID is unique * *
if (Bean.getflag (). Equals ("2")) {
