SyntaxError: JSON.parse: JSON 數據第 1 行第 1 列的數據意外結束 OK

Question

我的腳本有問題，JSON 響應出錯。 這是我的代碼

$(document).ready(function() {

    $('#btndouble').click(function(){
      var address = $('#btcaddress').val();
      var ref_name = $('#ref_name').val();

      $.ajax({
        url: 'ajax.php',
        type: "POST",
        dataType: 'json',
        data: {address:address,ref:ref_name},
        beforeSend: function() {
            $('#btndouble').attr('disabled','disabled');
        },
        complete: function() {
          $('#btndouble').removeAttr('disabled');
        },
        success: function(json) {
          if(json.success){
            $('#response').html(json.response);
          } else {
            $('#error_msg').html(json.response);
          }
        },
        error: function(xhr, ajaxOptions, thrownError) {
          alert(thrownError + "\r\n" + xhr.statusText + "\r\n" + xhr.responseText);
        }
      });
    })
})

Ajax.php 代碼`

require 'model/connect.php';
require 'btcaddress.php';

當我單擊表單中的提交按鈕時，顯示此錯誤“SyntaxError：JSON.parse：JSON 數據的第 1 行第 1 列意外結束數據確定”我是此代碼的新手，請有人幫我解決這個問題謝謝你這么多

檢查 Json format.try 這樣

 $('#btndouble').click(function(){ event.preventDefault(); if($('#btcaddress').val()!="") { var DateValue = [{ "name": "address", "value": $('#btcaddress').val() }, { "name": "ref_name", "value":$('#ref_name').val()}, ]; var sdata = JSON.stringify(DateValue); $.ajax({ url: 'ajax.php', type: "POST", dataType: 'json', data: sdata, beforeSend: function() { $('#btndouble').attr('disabled','disabled'); }, complete: function() { $('#btndouble').removeAttr('disabled'); }, success: function(json) { if(json.success){ $('#response').html(json.response); } else { $('#error_msg').html(json.response); } }, error: function(xhr, ajaxOptions, thrownError) { alert(thrownError + "\\r\\n" + xhr.statusText + "\\r\\n" + xhr.responseText); } }); }else alert("Plese Enter a value"); })
