javascript - 使用 jQuery 添加/删除多个输入类型文本

Question

我试图有两个输入部分，用户可以在其中添加或删除文本框，这就是我的代码的外观。

$(document).ready(function(){
    var maxField = 10; //Input fields increment limitation
    var addButton = $('.add_button'); //Add button selector
    var wrapper = ('.field_wrapper'); //Input field wrapper
    var fieldHTML = '<div><input type="text" name="field_name[]" value=""/><a href="javascript:void(0);" class="remove_button" title="Remove field">remove</a></div>'; //New input field html 
    var x = 1; //Initial field counter is 1
    $(addButton).click(function(){ //Once add button is clicked
        if(x < maxField){ //Check maximum number of input fields
            x++; //Increment field counter
            $(wrapper).append(fieldHTML); // Add field html
			//$(wrapper).slideDown(800);
        }
    });
    $(wrapper).on('click', '.remove_button', function(e){ //Once remove button is clicked
        e.preventDefault();
        $(this).parent('div').remove(); //Remove field html
        x--; //Decrement field counter
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="field_wrapper">
    <div>
        <input type="text" name="field_name[]" value=""/>
        <a href="javascript:void(0);" class="add_button" title="Add field">add</a>
    </div>
</div>

 </br>
 
  <div class="field_wrapper">
    <div>
        <input type="text" name="field_name[]" value=""/>
        <a href="javascript:void(0);" class="add_button" title="Add field">add</a>
    </div>
</div>

“删除”链接有效，但是当我尝试添加文本框时，文本框都会添加到两个部分中。有没有办法将文本框仅添加到按下“添加”链接的div？谢谢。

$(this.parentElement).append(fieldHTML);//添加字段 html

已编辑答案，因此两者最多可以有 10 个:

`$(document).ready(function(){
var maxField = 10; //Input fields increment limitation
var addButton = $('.add_button'); //Add button selector
var wrapper = ('.field_wrapper'); //Input field wrapper
var fieldHTML = '<div><input type="text" name="field_name[]" value=""/><a href="javascript:void(0);" class="remove_button" title="Remove field">remove</a></div>'; //New input field html 
$(addButton).click(function(){ //Once add button is clicked
    var theWrapper = $(this).closest(wrapper);
    var numOfChildren = theWrapper.children().length;
    if( numOfChildren < maxField){ //Check maximum number of input fields
        theWrapper.append(fieldHTML);
    }
});
$(wrapper).on('click', '.remove_button', function(e){ //Once remove button is clicked
    e.preventDefault();
    $(this).parent('div').remove(); //Remove field html
    x--; //Decrement field counter
});

});`
