json - How do I pass AJAX JSONP data into a function? -


i asked similar question already, discovered needed use ajax , jsonp, opened whole new world of hurt.

a company working has api privacy policy , terms of use. need create 2 different pages:

  • privacy policy
  • terms of use

so need search data them, find correct term in "tags" ('ext_privacy' , 'ext_member_terms', respectively), , use html code array rest of page.

the problem is, can't figure out how pass data ajax function, , @ point, don't know how drill down sections appropriately - thought external.data.results.tags, doesn't seem work.

here's site code:

<!doctype html> <html> <head>     <script src="http://code.jquery.com/jquery-latest.js"></script>     <title>privacy policy</title> </head> <body>     <div id="data">     </div>     <script>          $.ajax({             type: 'get',             url: 'http://guywhogeeks.com/test/test.json',             jsonpcallback: 'jsoncallback',             contenttype: 'application/json',             cache: 'true',             datatype: 'jsonp',             success: datafeed         });          function datafeed(external) {              //establishing htmlstring - testing see if function fires             var htmlstring = "hello, world!";              //i know way off - wanted add html htmlstring             /*$(external.data.results.tags).find(privacy).each(function() {                  $({                     text : external.data.results.html                 }).appendto(htmlstring)              });*/              $('#data').html(htmlstring);         }     </script> </body> </html>

here's (slightly modified) json - hosted here:

{"code":200,"status":"ok","data":     {"offset":0,"limit":20,"total":2,"target":"html_page","results":[         {             "id":"6",             "title":"privacy policy",             "description":"privacy policy",             "html":"<div class=\"right-rail\">\r\n<div class=\"module\">\r\n<h2 class=\"episode-guide-header\">web site privacy policy<\/h2>\r\n<div class=\"module-body corp-home-top\">\r\n<div class=\"corp-home-wrapper privacy\">\r\n<\/div>\r\n<!--corp-home-wrapper--><\/div>\r\n<!--module-body corp-home-top-->\r\n<div class=\"module-shadow\">&#160;<\/div>\r\n<\/div>\r\n<!--module--><\/div>\r\n<!--right-rail-->",             "tags":[                 "ext_privacy"             ]         },         {             "id":"66",             "title":"license , tou",             "description":"license agreement , terms of use",             "html":"<!doctype html>\r\n<html>\r\n    <head>\r\n        <title>license agreement , terms of use<\/title>\r\n    <\/head>\r\n    <body>\r\n       <div class=\"right-rail\">\r\n<div class=\"module\">\r\n<h2 class=\"episode-guide-header\"> license agreement , terms of use<\/h2>\r\n<\/div><\/body>\r\n<\/html>",             "tags":[                 "ext_member_terms"             ]         }     ]} }

i'd appreciate can give me.

you jsonp payload incorrect. server should return call "callback" function... in example, server should return:

jsoncallback( {"code":200,"status":"ok","data":     {"offset":0,"limit":20,"total":2,"target":"html_page","results":[         {             "id":"6",             "title":"privacy policy",             "description":"privacy policy",             "html":"<div class=\"right-rail\">\r\n<div class=\"module\">\r\n<h2 class=\"episode-guide-header\">web site privacy policy<\/h2>\r\n<div class=\"module-body corp-home-top\">\r\n<div class=\"corp-home-wrapper privacy\">\r\n<\/div>\r\n<!--corp-home-wrapper--><\/div>\r\n<!--module-body corp-home-top-->\r\n<div class=\"module-shadow\">&#160;<\/div>\r\n<\/div>\r\n<!--module--><\/div>\r\n<!--right-rail-->",             "tags":[                 "ext_privacy"             ]         },         {             "id":"66",             "title":"license , tou",             "description":"license agreement , terms of use",             "html":"<!doctype html>\r\n<html>\r\n    <head>\r\n        <title>license agreement , terms of use<\/title>\r\n    <\/head>\r\n    <body>\r\n       <div class=\"right-rail\">\r\n<div class=\"module\">\r\n<h2 class=\"episode-guide-header\"> license agreement , terms of use<\/h2>\r\n<\/div><\/body>\r\n<\/html>",             "tags":[                 "ext_member_terms"             ]         }     ]} });

in client, should define "jsoncallback" like:

jsoncallback(data) { // data regular javascript object @ point // can access 'data.data.results[0].html' without problem }

check more information: http://en.wikipedia.org/wiki/jsonp

hope helps.
