更改ID和类在包含html代码jquery的变量中

Question

我正在尝试做的是单击AddMore按钮我正在获取按钮的ID

 <div id="MemberCountDiv">
                <div class="MemberDescriptionAdd" style="display:none;">
                    <select name="MemberCountType" id="MemberCountTypeX" class="MemberCountTypeX form-control ">
                        <option selected="selected" value="">Condition</option>
                        <option value="<">Less Than (&le;)</option>
                        <option value=">">Greater Than (&ge;)</option>
                        <option value="=">Equal</option>
                    </select>
                    <select name="MemberCount" id="MemberCountX" class="MemberCountX form-control ">
                        <option selected="selected" value="">Members</option>
                        <option value="1">1</option>
                        <option value="2">2</option>
                        <option value="3">3</option>
                        <option value="4">4</option>
                        <option value="5">5</option>
                        <option value="6">6</option>
                        <option value="8">7 Or More Than 7</option>
                    </select>
                    <button id="RemoveX" class="btn btn-blue" type="button">Remove</button>
                </div>
            </div>

我保留了这个div,我点击的是

$(".AddMoreButton").click(function () {
        var type = $(this).val();
        var idname = $(this).attr("id");
        var id = idname.replace("AddMore", "");
        alert(id);
        var adddiv = $('#MemberCountDiv').html();
        alert(adddiv);
        adddiv.find('.MemberDescriptionAdd').attr('id', 'your-new-id');
        alert(adddiv);
    });

我想要做的是将id附加到id和类

错误:

adddiv.find is not function

Answer 1

这是因为adddiv是html字符串而不是元素的jquery对象.使用:

var adddiv = $('#MemberCountDiv');
alert(adddiv.html());
adddiv.find('.MemberDescriptionAdd').attr('id', 'your-new-id');
alert(adddiv.html());
