Question

我正在尝试重新创建https://jqueryui.com/autocomplete/#remote-jsonp 用我自己的数据库

test.php的内容

  <?php 
    $host = "localhost";
    $user = "root";
    $pass = "*";
    $databaseName = "easychartdb";
    $connect = mysqli_connect($host,$user,$pass,$databaseName);
    $sql = "Select * from `calendar`";
    $result = mysqli_query($connect,$sql);
    $json_array = array();  
    $array = mysqli_fetch_row($result);                                   
       while($row = mysqli_fetch_row($result))
          {
            $json_array[] = $row;
          }
    echo json_encode($json_array);
  ?>

tester.html的内容。从链接中更改的是源：test.php和错误函数

          $( "#log" ).scrollTop( 0 );
        }

    $( "#birds" ).autocomplete({
      source: function( request, response ) {
        $.ajax( {
          url: "test.php",
          dataType: "jsonp",

          success: function( data ) {
            response( data );
          }
            ,
          error: function (err) {
      console.error("error");
      console.log(err);
  console.log(err.stack);

}
        } );
      },
      minLength: 2,
      select: function( event, ui ) {
        log( "Selected: " + ui.item.value + " aka " + ui.item.id );
      }
    } );
  } );
  </script>
</head>
<body>

<div class="ui-widget">
  <label for="birds">Birds: </label>
  <input id="birds">
</div>

<div class="ui-widget" style="margin-top:2em; font-family:Arial">
  Result:
  <div id="log" style="height: 200px; width: 300px; overflow: auto;"                 
  class="ui-widget-content"></div>
</div>

控制台日志始终会引发错误

then: ƒ ( /* fnDone, fnFail, fnProgress */ )

任何人都可以帮助我解决这里的问题，谢谢！

Answer 1

您正在使用self.tFPeriodEndCurrent.inputView = self.datePicker，但没有返回回调。因此，有两种选择。将dataType更改为json或修正您的返回值：

tester.html：

//assume textfield contains 20/2/2019 , that should reflect in UIdatepicker when user Tap on textfield. 
how to acheive that! any help

test.php：

jsonp

代替

dataType: 'jsonp', jsonpCallback: 'callback',

Here，您可以找到有关jsonp的一些信息。
