javascript - 如何将 JSON 数据显示到动态输入文本字段中？

标签 javascript jquery html json ajax

我有一个通过 AJAX GET 方法传入的 JSON 数据是:JsonData 存储在 var trDataSecondTable 中当我这样做时显示 console.log(trDataSecondTable) .

{  
   "assessCatAmount":[  
      {  
         "assessmentNo":1,
         "assessmentType":"PRE",
         "assessCatId":1,
         "assessReason":"A",
         "assessAmount":1,
         "assessPenalty":2,
         "entryBy":"PCS",
         "rStatus":"1"
      },
      {  
         "assessmentNo":1,
         "assessmentType":"PRE",
         "assessCatId":1,
         "assessReason":"D",
         "assessAmount":3,
         "assessPenalty":4,
         "entryBy":"PCS",
         "rStatus":"1"
      },
      {  
         "assessmentNo":1,
         "assessmentType":"PRE",
         "assessCatId":2,
         "assessReason":"B",
         "assessAmount":5,
         "assessPenalty":6,
         "entryBy":"PCS",
         "rStatus":"1"
      },
      {  
         "assessmentNo":1,
         "assessmentType":"PRE",
         "assessCatId":2,
         "assessReason":"E",
         "assessAmount":7,
         "assessPenalty":8,
         "entryBy":"PCS",
         "rStatus":"1"
      },
      {  
         "assessmentNo":1,
         "assessmentType":"PRE",
         "assessCatId":3,
         "assessReason":"C",
         "assessAmount":9,
         "assessPenalty":10,
         "entryBy":"PCS",
         "rStatus":"1"
      },
      {  
         "assessmentNo":1,
         "assessmentType":"PRE",
         "assessCatId":3,
         "assessReason":"F",
         "assessAmount":10,
         "assessPenalty":10,
         "entryBy":"PCS",
         "rStatus":"1"
      }
   ]
}

我的表单是这样的，是动态类型的(可以通过单击“+”添加或可以通过按“-”删除)

首次加载页面时我的表单如下所示:

enter image description here

我需要将这六个 JSON 数据显示到此表单中。如果有 3 个 JSON 数据，则总共应该有 3 行数据。如果有 12 个 json 数据，则需要显示 12 行数据。在输入字段中。

	function sumIt() {
  $("#formContainer [type=number]").each(function() {
    var $row = $(this).closest(".row");
    var $fields = $row.find("[type=number]");
    var val1 = $fields.eq(0).val();
    var val2 = $fields.eq(1).val();
    var tot = (isNaN(val1) ? 0 : +val1) + (isNaN(val2) ? 0 : +val2)
    $row.find(".sum").text(tot);
  });
  var total = 0;
  $(".sum").each(function() {
    total += isNaN($(this).text()) ? 0 : +$(this).text()
  });
  $("#tot").text(total);
  return total;
}

$(".customs-table .remove:lt(1)").hide();  
$(".vat-table     .remove:lt(1)").hide();  
$(".excise-table  .remove:lt(1)").hide();  

$("#formContainer").on("click", "button", function() {
  var selector = "div.row";
  var $div = $(this).closest(selector);
  if ($(this).is(".add")) {
    var $newDiv = $div.clone();
    $newDiv.find(":input").val(""); // clear all
    $newDiv.find("[type=number]").val(0); // clear numbers
    $newDiv.find(".sum").text(0); // clear total
    $newDiv.insertAfter($div)
  }
  else {
    $div.remove();
     sumIt(); 
  }
  $(".customs-table .remove:gt(0)").show();  
  $(".vat-table     .remove:gt(0)").show();  
  $(".excise-table  .remove:gt(0)").show();  
});


$("#formContainer").on("input", "[type=number]", sumIt);

$("form").submit(function() {
  event.preventDefault();
  var user_profile = [];
  $(".row").each(function() {
    var $fields = $(this).find(":input");
    if ($fields.length > 0) {
      var cat = $(this).find("div>label").eq(0).text(); // use the label of the row
      var catId = ["","Customs","VAT","Excise"].indexOf(cat)
      user_profile.push({
        assessmentType: "PRE",
        assessCatID : catId, 
        assessReason: $fields.eq(0).val(),
        assessAmount: $fields.eq(1).val(),
        assessPenalty: $fields.eq(2).val(),
        assessTotal: +$fields.eq(1).val() + +$fields.eq(2).val() // the leading + makes it a number
      });
    }
  });
  console.log(user_profile);
  
});

我尝试使用 for 循环进行操作，但无法将它们显示到那些动态字段中。我怎样才能实现这一点？

更新的代码:

由于有海关、增值税、消费税，我需要它们的每个数字，例如 1,2。每个数字都以 1,2,3 等开头。 enter image description here

所以这就是我尝试的: 我添加了customNo类。

<div class="col-md-1 customNo">
            <label>Customs</label>
          </div>

为了显示 1,2,3，我声明了 3 个不同的变量。

var showEmpty=true;
  var i=1,j=1,k=1;
  $.each(data.assessCatAmount, function(_,cat) {
    showEmpty = false; // there was data
    var type = types[cat.assessCatId];
    var $newDiv = $("#formContainer").find("."+type+"-table").eq(0).clone(); 
    $.each(cat,function(key,value) {
    $(".customNo").append("<div><label for="name"> i </label></div>");
       var fieldName = key.replace("assess",type);
       var $field = $newDiv.find("."+fieldName);
       if ($field) $field.val(value);
       i=i+1;
    });
    $("#formContainer").append($newDiv)

所以我尝试了$(".customNo").append("<div><label for="name"> i </label></div>");它没有向我显示 1,2。我怎样才能得到这个？

最佳答案

您需要复制克隆部分

var types = ["","customs","vat","excise"]; // 1,2,3 must match class names
$.each(data.assessCatAmount, function(_,cat) {
  var type = types[cat.assessCatId];
  var $newDiv = $("#formContainer").find("."+type+"-table").eq(0).clone(); // clone the FIRST one
  $.each(cat,function(key,value) {
     var fieldName = key.replace("assess",type);
     var $field = $newDiv.find("."+fieldName);
     if ($field) $field.val(value);
  });
  $("#formContainer").append($newDiv)
});

您可能需要隐藏或填充前 3 个 div，因为我没有填充它们，我只用它们来克隆

还将总计移至底部，就像我在提交时所做的那样

var types = ["", "customs", "vat", "excise"]; // 1,2,3
function getText(str) {
  return $.trim(/\s/.test(str)?str.split(/\s+/)[1]:str);

}
