Question

我正在使用关闭按钮破坏模式的模态形式创建动态div，到目前为止效果很好。然后，我添加了一个按钮来添加新的div / forms项，但是这次不调用close按钮回调，而是关闭模式而不是破坏div本身。从 addNewRow 创建行时不调用回调函数。这是代码：

console.log("hello");

var myModal = $('#exampleModal'); 

var myForm = $('#exampleModal #myForm'); 
var value = $('#redactorArea3').val(); 
var result = jQuery.parseJSON(value); 

var recordsCounter = 0;

for (var index in result){

  var obj = result[index];
  var mydiv = '<div id="pepe'+index+'" class="input-group mb-3">';
  for (var property in obj){
    var attrName = property;
    var attrValue = obj[property]; 

   
   //myForm.append('<div class="form-group"><label>'+attrName+'</label><textarea class="form-control" id="exampleFormControlTextarea1" rows="1">'+ attrValue +'</textarea></div>');
   
    mydiv += '<div class="input-group-prepend"><span class="input-group-text">'+attrName+'</span></div><input type="text" class="form-control" id="field'+index+'"  value="'+attrValue+'">';

  }  
  mydiv += '<button id="remove' + index + '" class="btn btn-danger remove-me" >-</button></div>';
  myForm.append( mydiv);
  recordsCounter++;
}    
            
function addNewRow(){
    recordsCounter++;
    var mydiv = '<div id="pepe'+recordsCounter+'" class="input-group mb-3">';
    mydiv += '<div class="input-group-prepend"><span class="input-group-text"></span></div><input type="text" class="form-control" id="field'+recordsCounter+'">';
    mydiv += '<div class="input-group-prepend"><span class="input-group-text"></span></div><input type="text" class="form-control" id="field'+recordsCounter+'">';
    mydiv += '<button id="remove' + recordsCounter + '" class="btn btn-danger remove-me" >-</button></div>';
    myForm.append( mydiv);
  console.log("add row");
}

$('.remove-me').click(function(e){
                console.log("remove me");
                e.preventDefault();
                var fieldNum = this.id.charAt(this.id.length-1);
                var fieldID = "#field" + fieldNum;
                var pepeId = "#pepe" + fieldNum;
                $(this).remove();
                $(fieldID).remove();
                $(pepeId).remove();
                recordsCounter--;
            });

所以我上面的选择器不太正确，但这是一个有效的版本。另外，顺便说一下，您的addNewRow()方法不会添加名称和 Price 标签。

console.log("hello");

var myModal = $('#exampleModal'); 

var myForm = $('#exampleModal #myForm'); 
var value = $('#redactorArea3').val(); 
var result = jQuery.parseJSON(value); 

var recordsCounter = 0;

for (var index in result){

  var obj = result[index];
  var mydiv = '<div id="pepe'+index+'" class="input-group mb-3">';
  for (var property in obj){
    var attrName = property;
    var attrValue = obj[property]; 

   
   //myForm.append('<div class="form-group"><label>'+attrName+'</label><textarea class="form-control" id="exampleFormControlTextarea1" rows="1">'+ attrValue +'</textarea></div>');
   
    mydiv += '<div class="input-group-prepend"><span class="input-group-text">'+attrName+'</span></div><input type="text" class="form-control" id="field'+index+'"  value="'+attrValue+'">';

  }  
  mydiv += '<button id="remove' + index + '" class="btn btn-danger remove-me" >-</button></div>';
  myForm.append( mydiv);
  recordsCounter++;
}    
            
function addNewRow(){
    recordsCounter++;
    var mydiv = '<div id="pepe'+recordsCounter+'" class="input-group mb-3">';
    mydiv += '<div class="input-group-prepend"><span class="input-group-text"></span></div><input type="text" class="form-control" id="field'+recordsCounter+'">';
    mydiv += '<div class="input-group-prepend"><span class="input-group-text"></span></div><input type="text" class="form-control" id="field'+recordsCounter+'">';
    mydiv += '<button id="remove' + recordsCounter + '" class="btn btn-danger remove-me" >-</button></div>';
    myForm.append( mydiv);
  console.log("add row");
}

$('#myForm').on('click', '.remove-me', function(e){
debugger;
                console.log("remove me");
                e.preventDefault();
                var fieldNum = this.id.charAt(this.id.length-1);
                var fieldID = "#field" + fieldNum;
                var pepeId = "#pepe" + fieldNum;
                $(this).remove();
                $(fieldID).remove();
                $(pepeId).remove();
                recordsCounter--;
            });
