javascript - ASP.NET MVC 3 - Ajax 更新表 - 模型

Question

我正在尝试使用 ajax 更新记录列表，在表中表示，其中每条记录作为 javascript 删除链接。如果我预加载表格，RemoveLink 工作正常，但是一旦通过 ajax 更新了 div“RecordListPartialView”，它就不再工作了。

我用 firebug 检查生成的 html 代码对于每一行都是正确的。看起来浏览器并不知道新代码，因此它不会触发 javascript 链接。

谁能解释一下这是怎么回事？

(1) 下面是查看代码:

$(".RemoveLink").click(function () {
    var _id = $(this).attr("data-id");
    var recordToDelete = { id: _id };
    var json = $.toJSON(recordToDelete);
    $.ajax({
        url: '/MortagePayment/RemoveMortageRecord',
        type: 'POST',
        dataType: 'json',
        data: json,
        contentType: 'application/json; charset=utf-8',
        success: function (data) {
            $("#RecordListPartialView").empty();
            $("#RecordListPartialView").html(data.Message);
        }
    });
});
$(".AddLink").click(function () {
    var _year = $("#NewRecord_year").val();
    var _month = $("#NewRecord_month").val();
    var _mortageValue = $("#NewRecord_mortageValue").val();
    var newRecord = { year: _year, month: _month, mortageValue: _mortageValue };
    var json = $.toJSON(newRecord);
    $.ajax({
        url: '/MortagePayment/AddMortageRecord',
        type: 'POST',
        dataType: 'json',
        data: json,
        contentType: 'application/json; charset=utf-8',
        success: function (data) {
            $("#RecordListPartialView").empty();
            $("#RecordListPartialView").html(data.Message);

            $("#NewRecord_year").val(0);
            $("#NewRecord_month").val(0);
            $("#NewRecord_mortageValue").val(0);
        }
    });
});

<div id="RecordListPartialView">
    @Html.Partial("MortageRecordList", Model.MortageRecordList)
</div>

(2) 局部 View

<table id="mortageRecordListTable">
    <tr>
        <th colspan=4>Current reductions</th>
    </tr>
    <tr>
        <th>Year</th>
        <th>Month</th>
        <th>Value</th>
        <th></th>
    </tr>

    @foreach (var item in Model) {
        <tr id="row-@item.mortageRecordId">
            <td>
                @item.year
            </td>
            <td>
                @item.month
            </td>
            <td>
                @item.mortageValue
            </td>
            <td>                
                <p class="RemoveLink" data-id="@item.mortageRecordId">Remove</p>
            </td>
        </tr>
    }              
</table>

(3) 和 Controller :

[HttpPost]
public ActionResult AddMortageRecord(MortageRecord newRecord) {
    var mortageRecordSet = MortageRecordSet.GetMortageSet(this.HttpContext);
    if (ModelState.IsValid) 
        mortageRecordSet.AddMortageRecord(newRecord);
    string partialViewHtml = RenderPartialViewToString("MortageRecordList", mortageRecordSet.GetMortageItems());

    return Json(new { Success = true, Message = partialViewHtml });
}

[HttpPost]
public JsonResult RemoveMortageRecord(int id) {
    var mortageRecordSet = MortageRecordSet.GetMortageSet(this.HttpContext);
    mortageRecordSet.RemoveMortageRecord(id);              
    string partialViewHtml = RenderPartialViewToString("MortageRecordList", mortageRecordSet.GetMortageItems());

    return Json(new { Sucess = true, Message = partialViewHtml });
}

Answer 1

如果我没理解错的话。

If I preload the table, the RemoveLink works fine, but once the div "RecordListPartialView" is updated via ajax, It no longer works.

使用 .live 更改您的 .click 事件>

$(".RemoveLink").live("click",function(){
    //any click event code comes here
});
