javascript - 使用 jQuery 添加删除输入字段

Question

我在单击按钮时添加输入字段，同时提供删除按钮以删除输入字段。但是我的删除按钮没有删除输入字段，而是将我带到页面顶部...

<div class="input_fields_wrap">
<div class="form-group">
<label class="col-md-3 control-label" for="example-text-input">Preferred Work Location</label>
<div class="col-md-3">
<input type="text" id="loc" name="Work_Location[]" class="form-control" >
</div>
<button class="add_field_button">Add More Locations</button>
</div>
</div>

下面是当我点击按钮时添加更多文本框的 jQuery

<script>
$(document).ready(function() {
    var max_fields      = 10; //maximum input boxes allowed
    var wrapper         = $(".input_fields_wrap"); //Fields wrapper
    var add_button      = $(".add_field_button"); //Add button ID

    var x = 1; //initlal text box count
    $(add_button).click(function(e){ //on add input button click
        e.preventDefault();
        if(x < max_fields){ //max input box allowed
            x++; //text box increment
            $(wrapper).append('<div class="form-group"><label class="col-md-3 control-label" for="example-text-input">Preferred Work Location</label><div class="col-md-3"> <input type="text" id="loc" name="Work_Location[]" class="form-control"  ></div><a href="#" class="remove_field">Remove</a></div>'); //add input box
        }
    });

    $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
        e.preventDefault(); $(this).parent('div').remove(); x--;
    })
});
</script>

我有一个例子给你，你可以做的更简单

function closeMe(element) {
  $(element).parent().remove();
}

function addMore() {
  var container = $('#list');
  var item = container.find('.default').clone();
  item.removeClass('default');
  //add anything you like to item, ex: item.addClass('abc')....
  item.appendTo(container).show();
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<ul id="list">
    <li class="default" style="display: none;">
        <input type="text" /><span style="cursor: pointer;" onclick="closeMe(this);">close</span>
    </li>
</ul>
<button onclick="addMore();">Add</button>
