解决方案

下面是一个克隆机制，克隆事件以及 HTTP ：//jsfiddle.net/dg30gj27/

请注意，您在使用ASP标记在你的榜样，你应该在你的例子是使用HTML标签：
HTTP：//$c$c.runnable.com / UjB_wxmQpvw8AAAw / ASP净如何使用的，DropDownList的
点击运行和检查结果的HTML。

此方法presented这里克隆所有客户端的事件，则可能是事件处理上code后面的问题，您需要检查事件源以执行服务器上的正确动作。

  //原附加数据元素
变量$ ELEM = $（#destinations）。数据（改编，[1]），
    // withDataAndEvents（默认：false）类型：Boolean
    克隆= $ elem.clone（真）
    //深拷贝prevent数据共享
    。数据（改编，$ .extend（[]，$ elem.data（改编）））;cloned.attr（ID，cloned.attr（ID）+_cloned）;
cloned.find（*）。每个（函数（）{
    如果（$（本）.attr（ID）=不确定和放大器;！＆安培; $（本）.attr（ID）长度的方式＆gt; 0）
    {
        $（本）.attr（ID，$（本）.attr（ID）+_cloned）;
    }
}）;
的console.log（复制）;
克隆prependTo（包装）。
 

I have a div which contains a a dropdown with data bound to it and an input type text datepicker and a textbox. I want to make a clone of the div with a new id of clone, input type date picker, textbox and dropdownlist and bound data to cloned dropdown. How can I do this?

I'm using the below code it cloning it changing the id of div but not its child elements and the cloned input type text date picker gets disabled.

var toAddCloneCount = 0;
        
function AddDestination() {
    var clone = $("#toAdd").clone(true);
    clone.show();
    clone.attr('id', 'toAdd' + toAddCloneCount++).insertAfter("#toAdd");
    clone.find("#days").attr('id', 'days' + toAddCloneCount);
    clone.appendTo("#destinations");
}

<div id="destinations">
    <div id="toAdd">
        <table style="width: 100%;">
            <tr>
                <td class="auto-style8">To </td>
                <td>
                    <asp:DropDownList ID="dropDownList2" runat="server" onchange="CheckCity()" DataValueField="CityId" DataTextField="CityName" Height="100%" Width="95%"></asp:DropDownList>
                </td>
                <td>Days to Stay</td>
                <td>
                    <asp:TextBox ID="days" Width="30%" Height="100%"  onkeypress="return false" onKeyDown="return false" TextMode="Number" Min="1"  runat="server" Text="1"></asp:TextBox>
                </td>
                <td>
                    <p>
                        Date: 
                        <input type="text" class="getCurrentDate"  id="toDate" onkeypress="return false" onkeydown="return false" />
                    </p>
                </td>
                <td>
                    <asp:LinkButton ID="LinkButton2" OnClientClick="AddDestination(); return false;" CssClass="divshow" runat="server">+Add</asp:LinkButton>
                </td>
            </tr>
        </table>
    </div>
</div>

解决方案

Here is a clone mechanism, cloning events as well http://jsfiddle.net/dg30gj27/.

Note, you are using asp tags in your example, you should use HTML tags in your example as: http://code.runnable.com/UjB_wxmQpvw8AAAw/asp-net-how-to-use-dropdownlist click on run and inspect the resulted Html.

This method presented here clone all client events, you may have problems with events handling on code behind, you need to check event source in order to perform the correct action on server.

// Original element with attached data
var $elem = $( "#destinations" ).data( "arr", [ 1 ] ),
    //withDataAndEvents (default: false) Type: Boolean"
    cloned = $elem.clone( true )
    // Deep copy to prevent data sharing
    .data( "arr", $.extend( [], $elem.data( "arr" ) ) );

cloned.attr("id", cloned.attr("id") + "_cloned");
cloned.find( "*" ).each(function(){
    if ($(this).attr("id") != undefined && $(this).attr("id").length > 0)
    {
        $(this).attr("id", $(this).attr("id") + "_cloned");
    }
});
console.log(cloned);
cloned.prependTo(".wrapper");
