javascript - Using Ajax to read a csv/text file -


i want use ajax read text file , convert array fill in select box. problem cannot figure out why ajax code not work. every time test out code in chrome, error jquery:

xmlhttprequest cannot load file:///c:/filepath.../attributecategories.txt. cross origin requests supported protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource. 

here's html page:

<html> <head>     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>     <script type="text/javascript">     $(document).ready(function(){         $('#btn').click(function(){             $.ajax({                 type: "get",                 url: "attributecategories.txt",                 datatype: "text",                 success: function (data) {                     processdata(data);                 }             });          });          function processdata(data){             var attrcsv = data.split("\n"); //----------------------------------split csv rows             var ctgylist = attrcsv[0].split(","); //----------------------------split first row categories              for(var = ctgylist.length + 1; > 0; i--){//---------------------trim empty items off array                 if(isnan(ctgylist[i]) == true){ctgylist.splice(i,1);}             }              $('#sel')[0].options.length = 0;//----------------------------------clear select options             for(var = 0; < ctgylist.length; i++){//-------------------------build select array                 $('#sel').append($('<option>',{value:i + 1,text:ctgylist[i]}));             }         }     });     </script>   </head> <body>     <div>         <table>             <tr><td><button id="btn">click me!</button></td></tr>             <tr><td><select id="sel"></select></td></tr>         </table>      </div> </body> 

all of files (html , text file) in same folder. or clarification helpful, thanks.

the problem explained in error message. security reasons, browser not allow request asynchronously url different domain page running ("cross-origin request"). more information see https://en.wikipedia.org/wiki/same-origin_policy , https://developer.chrome.com/extensions/xhr.
