javascript - how to get the encoded data by json_encode in the java script file -

i encoding file data using json_encode , when send encoded data in javascript:

this php code (using codeigniter upload file):

$file_info = $this->upload->data(); echo json_encode($file_info); 

and use data in javascript file:

'onuploadsuccess' : function(file, data, response) {       alert('the file saved to: ' + data); } 

how can use file_name or other strings encoded?!

for example how can use:

'onuploadsuccess' : function(file, data, response) {   alert('the file name is: ' + file_name); } 

you have 3 variables in response. see each 1 when code executed, use console.log().

'onuploadsuccess' : function(file, data, response) {     console.log('\n"data" variable:')     console.log(data);     console.log('"file" variable:')     console.log(file);     console.log('\n"response" variable:')     console.log(response); } 

now open javascript log (f12 in chrome, shift+f5 think in firefox). json data should have been converted object. if it's in json form, add json.parse(data).

objects backbone of javascript. select information in object named data, use data.property. data.file_name should return "83274983279843.jpg", data.type return type, etc.

edit: after discussion in chat issue didn't parse json. incorrectly told reverse variable order.

here fixed code:

'onuploadsuccess' : function(file, data, response) {      data = json.parse(data)      alert('the file : ' + data.file_type);  }
