javascript - Populate second input text based on previous one -


i'm building form insert in text input, number, , in next input text, auto populate name matches number in db. i've tested many "solutions" saw here , on other sites none worked.

my script code is:

$("#numero").blur(function () {     $.post(convoc.php, { numero: $(this).val() }, function (data) {         $("#nome").val(data);     }); });

my convoc.php code:

if (@$_post['numero'] != "")         $numero = $_post['numero']; $query  = "select nome ******* numero = $numero";     $result = mysql_query($query);     $row = mysql_fetch_array($result);      echo json_encode($row['nome']);

(this working well, because i've tested echo , it's printing correct name)

the id of first input text is: "numero" , id of second input "nome".

is there i'm doing wrong in script function?

the html code is:

<body onload="load()" style="padding-top: 20px;">     <form action="convoc.php" method="post">         <div id="myform">         <table align="center"> <tr>             <td><input type="text" id="numero" name="numero"></td>             <td><input type="text" id="nome" name="nome"></td>         <td><input type="button" id="add" value="convocar" onclick="javascript:addrow()"></td>     </tr>  </table> </div>  </form> </body>

the js code is:

function addrow() {      var numero = document.getelementbyid("numero");     var nome = document.getelementbyid("nome");     var table = document.getelementbyid("mytabledata");       var rowcount = table.rows.length;     var row = table.insertrow(rowcount);      row.insertcell(0).innerhtml= '<input type="button" value = "delete" onclick="javacsript:deleterow(this)">';     row.insertcell(1).innerhtml= numero.value;     row.insertcell(2).innerhtml= nome.value; }  function deleterow(obj) {      var index = obj.parentnode.parentnode.rowindex;     var table = document.getelementbyid("mytabledata");     table.deleterow(index);  }  function load() {      console.log("page load finished");  }

(and no, i'm not receiving error in browser)

change script code below.

the first parameter convoc.php should 'convoc.php'.

$(function(){     $("#numero").blur(function () {         //use $.ajax     $.ajax({         url:'convoc.php',         datatype:'json', //the datatype should json because returning in json format         data : {numero: $(this).val()},         success:function(data){         $("#nome").val(data.result);         }     });     }); });

also change php code below.

echo json_encode(array("result"=>$row['nome']));
