javascript - 如何使用 jquery 将从服务器文件获取的 JSON 值填充到创建的 HTML 表单中？

Question

仅供引用:我没有使用引导模态框来弹出窗口。

我的表格每行都有按钮，用于在弹出的模式框中显示详细信息。

我附上了 dashboard.html、modal.js、modal.css 和 modal.php 所需的部分代码.

我缺乏jquery的概念来将元素添加到表单并通过PHP分配返回的JSON文件的值，然后将表单添加到div标签类modal-content。弹出模式框的 CSS 在按钮单击时也不起作用。

此外，我想删除 class modal-content 中以前的 html 表单标签，因为每次新行单击都会弹出新表单，用户可以在其中编辑和更改行的值。

您可以通过查看下面的屏幕截图获得更清晰的图片。

文件dashboard.html，该文件有调用modal.js的按钮

此 modal.js 文件将在每次单击新按钮时获取行 ID，并构建 HTML 表单，以便使用该 HTML 表单弹出模式框。

$(document).ready(function() {

    $('[name="leadidclick"]').click(function(e){

      e.preventDefault();
      // var leadid = $('[name="leadidclick"]').val();

      var leadid = $(this).val();

      alert("You clicked Leadid: " + leadid);

      $.ajax({

        type: "POST",
        url: './server/modal.php',
        data: {

          'leadid': leadid

        },        
        success: function(data){

           var result = $.parseJSON(data);
           console.log(result);

           console.log(result.length)
          //Modal Box to POP UP HERE

           $.each(result, function(key, value) {

                    $form = $("<form action='' method='POST'></form>").attr("id", value['Lead_Id']);


                   //This value assigning based on JSON Key value pair is also not working


                    $form.append('<label>Lead Id: </label><input type="text" name="leadid" ').attr("id", value['Lead_Id']);

                    $form.append('<label>Lead Name: </label><input type="text" name="leadname">').attr("value", value['FirstName']+" "+value['LastName']); 

                    $form.append('<label>Company: </label><input type="text" name="company" ').attr("value", value['Company']);


                    $form.append('<input type="button" value="button">'); 

                    i = i + 1;

                });


          $( ".modal-content" ).append( $form );

          //This change in CSS is not working

          $('#myModal').css("display", "show");         


        }

      });

    });

});

用于显示模态的文件modal.css

/* The Modal (background) */
.modal {
  display: none; /* Hidden by default */
  position: fixed; /* Stay in place */
  z-index: 1; /* Sit on top */
  left: 0;
  top: 0;
  width: 100%; /* Full width */
  height: 100%; /* Full height */
  overflow: auto; /* Enable scroll if needed */
  background-color: rgb(0,0,0); /* Fallback color */
  background-color: rgba(0,0,0,0.4); /* Black w/ opacity */

}

/* Modal Content/Box */
.modal-content {
  background-color: #fefefe;
  margin: 15% auto; /* 15% from the top and centered */
  padding: 20px;
  border: 1px solid #888;
  width: 80%; /* Could be more or less, depending on screen size */
}

/* The Close Button */
.close {
  color: #aaa;
  float: right;
  font-size: 28px;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: black;
  text-decoration: none;
  cursor: pointer;
}

@特鲁普蒂·巴拉德我收到模式框弹出显示的控制台错误，并且我无法弹出模式框(我正在使用不带 Bootstrap 的模式框)。

Answer 1

在文件中dashboard.html您必须在模型代码 ex 中给出 div。 <div id="formapp">

<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">&times;</span>

    <p>This is Modal Box</p>                                        
    <div id="formapp">
    </div>
  </div>

</div> 

在ajax中

 $.ajax({

        type: "POST",
        url: './server/modal.php',
        data: {

          'leadid': leadid

        },        
        success: function(data){

           var result = $.parseJSON(data);
           console.log(result);

           console.log(result.length)
          //Modal Box to POP UP HERE

            $('#formapp').empty(); // first empty division content 
            var form=''; //declare var
           $.each(result, function(key, value) {

                    form = $("<form action='' method='POST'></form>").attr("id", value['Lead_Id']);


                   //This value assigning based on JSON Key value pair is also not working


                    form.append('<label>Lead Id: </label><input type="text" name="leadid" value="'+value['Lead_Id']+'">');

                    form.append('<label>Lead Name: </label><input type="text" name="leadname" value="'+value['FirstName']+" "+value['LastName']+'">');

                    form.append('<label>Company: </label><input type="text" name="company" value="'+value['Company']+'">');


                    form.append('<input type="button" value="button">'); 

                    i = i + 1;

                });


          $( "#formapp" ).html( form );

          //This change in CSS is not working

          $('#myModal').show();         


        }

      });

或者不需要$.each()对于单个记录只需使用 result[0]['Lead_Id']

还有$form被视为引用。在jquery中使用var声明变量
