javascript - 如何使用jquery删除onclick生成的多个div元素

Question

我可以使用单击添加一个 div 内容，并且可以生成多个或更多，但我也想在用户单击删除按钮时删除生成的 div。我已经尝试了一些，但它只删除了一次。如果我生成了一个点击然后当我点击删除时它被删除但是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>');
            $(this).after(domElement);
        });
    
});

 function clearBox(removechild)
    {
        document.getElementById('removechild').innerHTML = "";
    }
    $("#removechild").html("");

Answer 1

• 用类(子)将整个“部分”包裹在一个 div 中。
• 从一个 div 中删除了 id“removeChild”，因为你不应该有超过 1 个 id具有该值。
• 删除了内联的 onclick 事件并替换为一个事件，用于删除离您点击的按钮最近的部分。
• 向删除按钮添加了一个类 (removeChild)，以便我们可以使用该类轻松设置点击事件。

$(document).ready(function() {
       
        $("button[name='addDom']").click(function() {
            
            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>');
