能够在phonegap中发送和接收json数据的Javascript文件

Question

Which javascript files must be available either in client-side or server-side for you to be able to send and receive json data in your BlackBerry phonegap application.

I see this often omitted in all the solutions to json-related questions that have been posted.

I am completely new to phonegap and jQuery and so I need help also I am trying to send form details (like firstName and lastName) to a php file on the server-side.

So that the data would be processed by the php and the record would be stored on my database.

Can some one work me through how to send the data using json?

Answer 1

You can get detail on Json integration in phonegap from this blog .

this blog will explain through a simple example how you can use JSON to ease the client-server data transmission.

Don't bother about server site, server team (PHP/Java) will take care of it.
In phonegap app every logic is buid in javascript, so in your case if you want to send some information to server, you need to create json object and append it to $.ajax function and same function to receive the response from server:

$.ajax({  
   url:'stringURL',  
   beforeSend: function(x) {      
     x.setRequestHeader('Authorization','username/pwd');  
   },  
   dataType:"json",  
   contentType:'application/json',  
   timeout:10000,  
   type:'POST', 
   data : {
     //append json data here if you want to send some data to server
   }, 
   success:function(data) {  
     alert(data); // here you will get json data on success, parse it like key-value mechanism in js 
   },  
   error:function(XMLHttpRequest,textStatus, errorThrown) {     
     alert("Error status :"+textStatus);  
     alert("Error type :"+errorThrown);  
     alert("Error message :"+XMLHttpRequest.responseXML);  
   }
});

Please have a look at this blog to write php-web service or share with you server team.
