问题描述

我通过AJAX GET方法获得的JSON数据是:JsonData存储在var trDataSecondTable中，并在我执行console.log(trDataSecondTable)时显示.

I have a JSON data coming through AJAX GET method is:The JsonData is stored in var trDataSecondTable and displayed when I did console.log(trDataSecondTable).

我的表单看起来像是动态类型(可以通过单击"+"添加，也可以通过按-"删除)

My form looks like this which is dynamic type (can be added by clicking "+" or can be deleted by pressing "-")

第一次加载页面时的表单如下:

My form when page is loaded first looks like :

我需要将这六个JSON数据显示为这种形式.如果有三个JSON数据，那么应该与数据一起总共三行;如果有十二个JSON数据，则需要与数据一起出现十二行在输入字段中.

	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() {

我尝试使用for循环进行操作，但无法将其显示到那些动态字段中.我如何实现这一目标?

I tried to manipulate using the for loop but not able to show them into those dynamic field.How can i achieve this?

更新代码:

由于有习俗，vats，excise，我需要他们的每个数字都像1,2.每个数字以1,2,3开头，依此类推.

Since there are customs,vats,excise i need their each number like 1,2.Each of their start with 1,2,3 so on.

这就是我尝试的方法:我添加了customNo类.

So here is what i try:i added customNo class.

<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.

and to show 1,2,3 i declared 3 different variable.

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>");，它没有显示1,2.我怎么能得到这个?

So i tried $(".customNo").append("<div><label for="name"> i </label></div>"); it is not displaying me 1,2. How can i get this?

推荐答案

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，我只使用它们从中进行克隆

You may need to hide or fill the first 3 divs since I do not fill them, I only use them to clone from

也像我对提交所做的那样将总数移到底部

Also move the total to the bottom like I did with the submit

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

}
var data = {
  "assessCatAmount": [{
