return value of ajax call

[hiral]

Hi All,

I have one function which is used to validate IPv4 address. Let me know what will be the return value of this function.

here as per my understanding if ipv4 address is not valid it will display me message but if it true then what it will do?

What will be the return value of this function?

My call of this function is like
,saveIp(ipv4){
   
   if(ipv4 != ""){
          this.validateIPv4();
   }
} // save Ip ends here


// function for validating IPv4 address 
    ,validateIPv4:function(IPvalue){
        
        Ext.Ajax.request({
            url: script_path + 'managedevice/managedevice.php', 
            params: {
               mode:"checkIpv4",
               ipv4:IPvalue
            }, 
            success: function(response){
              var o = Ext.decode(response.responseText);
              alert(o.success);             
              switch(o.success){
                  case true:  // Success                   
                      return;                                        
                  break;
                  case false:  // Fail    
                    Ext.MessageBox.alert('Error','Invalid Ipv4 address.');
                    return;                        
                  break;
              }
            },
            failure: function(response){
              var result=response.responseText;
              Ext.MessageBox.alert('error','could not connect to the database. retry later');      
            }
         });    
            
    } // eof of validateIPv4

You can't do that. Ajax is asynchronous

Hi Animal,

Can you give some idea to do this?

Is there any way that I can check something from server side and return like this way?

Thanks

It is possible to kludge Ajax to return synchronously. But not a good idea. See hendricd's Ajax UX.

The proper way it to chain events. Its always possible to do this, it just means unlearning a bit of ingrained procedural programming techniques and learning event driven techniques
