Question

我可以使用点击添加div内容，并且可以生成多个或更多但我还想在用户单击删除按钮时删除生成的div。我尝试了一些，但它只删除一次。如果我生成一个点击，然后当我点击删除它，但当我生成两个或更多时，它不起作用。

$(document).ready(function() {
       
        $("button[name='addDom']").click(function() {
            
            var domElement = $('<div class="row " id="removechild"><hr><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">First Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="first_name" placeholder="First Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Last Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="last_name" placeholder="Last Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Gender</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"> <option value="">Male</option><option value="">Female</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Date of Birth</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input type="date" class="form-control" id="exampleInputDOB1" placeholder="Date of Birth" required="required" style="width:124%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Class Coordinator (if applicable)</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="class_coordinator" placeholder="Class Coordinator Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div></div><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">School Currently Attending</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="school" placeholder="School Currently Attending" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Relation with child</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span> <input name="relation" placeholder="Relation with child" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Types of soccercric</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"><option value="">Soccer</option><option value="">Cricket</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Child medical condition <br> <span style="font-size:10px">Please indicate any relevant medical conditions or allergies your child may have (not required if your child has no relevant medical issues)</span></label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="relation" placeholder="Child medical condition" class="form-control" type="text" required="required" style="width:200%"></div></div></div</div</div><br><br><br><button onclick="clearBox()" class="btn btn-danger">Remove Child</button><hr>');

Answer 1

包裹整个＆＃34;部分＆＃34;在一个有班级（孩子）的div中。
删除了ID＆＃34; removeChild＆＃34;来自div，因为你不应该有超过1个id 有这个价值。
删除了您的内联onclick事件并替换为一个事件删除最靠近您单击按钮的部分。
在删除按钮中添加了一个类（removeChild），以便我们可以使用该类轻松设置click事件。

Answer 2

在addDom中点击添加此代码

   var domElement = $('<div class="child"><div class="row "><hr><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">First Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="first_name" placeholder="First Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Last Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="last_name" placeholder="Last Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Gender</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"> <option value="">Male</option><option value="">Female</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Date of Birth</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input type="date" class="form-control" id="exampleInputDOB1" placeholder="Date of Birth" required="required" style="width:124%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Class Coordinator (if applicable)</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="class_coordinator" placeholder="Class Coordinator Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div></div><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">School Currently Attending</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="school" placeholder="School Currently Attending" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Relation with child</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span> <input name="relation" placeholder="Relation with child" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Types of soccercric</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"><option value="">Soccer</option><option value="">Cricket</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Child medical condition <br> <span style="font-size:10px">Please indicate any relevant medical conditions or allergies your child may have (not required if your child has no relevant medical issues)</span></label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="relation" placeholder="Child medical condition" class="form-control" type="text" required="required" style="width:200%"></div></div></div</div</div><br><br><br><button class="removeChild" class="btn btn-danger">Remove Child</button><hr></div>');
$(this).after(domElement);

除此之外粘贴

$(document).on('click','button.removeChild',function(){
     $(this).closest('div.child').hide();
 });

它会起作用！

Answer 3

试试这个：

$('addBtn').click(function(){
    var $div = $('<div class="test">...</div>');
    $(this).after($div);
})

$('.removeBtn').click(function(){
    var $div = $('.test').last();
    $div.length && $div.remove();
})

Answer 4

您应该将表单包装成div然后删除div，如下所示：

＆＃13;

var id = 0;
$(document).ready(function() {
       
        $("button[name='addDom']").click(function() {
            
            var domElement = $('<div class="rowItem"><div class="row" id="removechild"><hr><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">First Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="first_name" placeholder="First Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Last Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="last_name" placeholder="Last Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Gender</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"> <option value="">Male</option><option value="">Female</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Date of Birth</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input type="date" class="form-control" id="exampleInputDOB1" placeholder="Date of Birth" required="required" style="width:124%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Class Coordinator (if applicable)</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="class_coordinator" placeholder="Class Coordinator Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div></div><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">School Currently Attending</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="school" placeholder="School Currently Attending" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Relation with child</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span> <input name="relation" placeholder="Relation with child" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Types of soccercric</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"><option value="">Soccer</option><option value="">Cricket</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Child medical condition <br> <span style="font-size:10px">Please indicate any relevant medical conditions or allergies your child may have (not required if your child has no relevant medical issues)</span></label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="relation" placeholder="Child medical condition" class="form-control" type="text" required="required" style="width:200%"></div></div></div</div</div><br><br><br><button onclick="clearBox(this)" class="btn btn-danger">Remove Child</button><hr></div>');
            $(this).after(domElement);
        });
    
});

 function clearBox(removeChild)
    {
        $(removeChild).parentsUntil('.rowItem').html('');
    }

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button name="addDom" class="btn btn-warning"> Add Child</button>

＆＃13;

我正在使用jQuery的parentUntil来获取包装div并删除div中的所有项目。

Answer 5

您需要分配一个唯一ID，然后在clearBox函数中提供此唯一ID。

$(document).ready(function() {
    var count = 0;

    $("button[name='addDom']").click(function() {
        var uniqueID = "removechild-" + count,
            html = '<div class="row" id="' + uniqueID + '">row of stuff<button onclick="clearBox(\'' + uniqueID + '\')" class="btn btn-danger">Remove Child</button></div>';

        $(this).after(html);

        count++;
    });
});

function clearBox(idToRemove) {
    document.getElementById(idToRemove).innerHTML = "";
}

Answer 6

正如我和@guradio在评论中提到的，您的ID应该是唯一的。最简单的方法是使用一个全局整数变量，该变量附加到每个元素ID然后递增：

var elemIndex = 0;
createElement(){
    var newId = "someElement" + elemIndex;
    var domElement = '<div id="'+ newId +'"'>...</div>';
}

您的删除按钮单击应该调用clearBox方法，填充唯一ID（看起来您的方法已经开始支持参数）：

clearBox(elementId){
    document.getElementById(elementId).innerHtml = "";
}

按钮（在构建元素字符串时会出现）：

var domElement = '...<button type="button" onclick="clearBox('+ newId +')">Clear</button>...';
