jquery - JSON.parse: unexpected character when receiving assoc array from PHP json_encode -

-

update

so jquery.post() function receives valid json. know attribute "json" in function call should enough original array , .parsejson() not necessary. guess that's why syntax error when using function.

but somehow i still can't access array without .parsejson(). in fact, when use typeof(data) it's still string. can write console , it's still valid json.

how use array (originally associated php array encoded once via json_encode()) normal associated array in javascript?

original post

i've been getting syntax error days , it's driving me crazy. read lot of posts , know must super simple thing i'm missing. please help. in advance.

var institute = $.post("../libraries/load_content.php",     {         funct:   "getinstituteaddress",         ins_name: "institut für informatik",         ins_city: "kiel"     }, "json");     institute.done(function(data) {         alert(data);         var ins_data = $.parsejson(data); // <-- throws syntax error         $("#street").empty().val(ins_data['ins_street']);         $("#number").empty().val(ins_data['ins_number']);         $("#postalcode").empty().val(ins_data['ins_postal_code']);     }, "json");     institute.fail(function(data) {         console.log("retrieving institute data failed. returned:"+data);     });

the jquery.post() function calls php script, fetches required data db , returns associative array json_encode().

this works fine till point.

{"ins_name": "institut für informatik",  "ins_street": "hrsl",  "ins_number": "42",  "ins_postal_code": "24118",  "ins_city": "kiel"}

above alert returned string , jsonlint validator tells me it's valid json.

so copied string directly parsejson() call. worked fine. why not variable?

here's tried:

  • i read missing single/double quotes. no luck here. added them in multiple variations acound string.
  • i read parsejson function not required in such environment. dropped function call. syntax error of course disappears, can't read json normal array fields emptied.
  • i tried replacing .post() function .ajax(), adding missing arguments... same effect.
  • i changed datatype attributes html or text. again no luck.
