Sencha touch 2 for cross-origin access

When you see thisArticleI believe you also know why cross-origin access is required! I will not talk about it here. In sencha touch 2, cross-origin access can be implemented using ext class library to provide our class Ext. data. jsonp. If you want to submit a request, you can use the request () method as follows:

When submitting a request, you can write it like this

 1 Ext. Data. jsonp. Request ({
 2 URL: 'http: // api.xxx.com ',
 3 Params :{
 4           //  PASS Parameters  
  5 },
 6 Timeout: 30000,//  Timeout  
  7 Callbackkey :'', //  The callback function name. The default value is callback.  
  8 Callback: Function (){
 9           //  The callback function is executed no matter whether the request is successful or not.  
  10 },
 11 Success: Function (Result ){
 12           //  Run catch when the request is successful.  
  13 },
 14 Failure: Function (){
 15           //  Perform the operation when the request fails.  
  16 }
 17 });
