当数据通过ajax

Question

我想通过使用if else条件在一个变量（check）中添加两个变量（类textbox和hiddentxtbox）值，并且我想在ajax中传递那个变量（check）。我想如果有人选择数据库头选项之类的话firstname，lastname然后下拉值通过复选框，否则textbox值通过复选框。在我的脚本中，我已经传递了检查变量，如下所示： -  data：{check：textbox，oldval：textbox1，hiddentxtbox：hiddentxtbox，olddropval：textbox2} 如上面的代码，只有check变量有一个值textbox。我想如果有人选择数据库标题选项，如firstname，lastname，则下拉值通过复选框，如check：hiddentxtbox else check：textbox

<script>
  $(document).ready(function(){
    $('#submit').click(function(){

    var  hiddentxtbox=[];
    var textbox = [];
    var textbox1 = [];
    var textbox2= [];

    var check = [];
    $('.check').each(function() {
      if ($(this).is(':checked')) {
        var current = $(this).val();

        //alert(current);
        textbox.push($(this).parents("tr").find(".textbox").val())
        textbox1.push($(this).parents("tr").find(".textbox1").val())
        textbox2.push($(this).parents("tr").find(".textbox2").val())
        hiddentxtbox.push($(this).parents("tr").find(".newhiddenBox").val())
      }
      check.push($(this).val());
    });
    $.ajax({
      url: 'practice.php',
      type: 'post',
      data: {check: textbox, oldval: textbox1, hiddentxtbox: hiddentxtbox, olddropval: textbox2},
      success: function (data) {
          alert(data);
      }
    });
    return false;
  });
});
</script>
