Question

我有一个局部视图，打开一个对话框，用于输入一些数据。单击该按钮后，将执行Ajax调用以重置该部分视图和另一个视图。当我单步执行代码时，一切似乎都正常工作，但是当我打开局部视图备份时，数据仍然在框中。我在这个问题Caching issue with loading partial views into JQuery dialogs之后找到了一些成功，但是当我实现时，第二次使用它时按钮不起作用。我的代码如下：

jQuery和Ajax刷新包含其他部分视图的视图和视图：

<script type="text/javascript" charset="utf-8">
$(document).ready(function () {
    $('#ChangeHeatName').click(function (e) {
        var tdata = $('#form1').serialize();
        var origname = $('#HeatNameDiv').find('input[name="heatName"]').first().val();
        var newname = $('#HeatNameDiv').find('input[name="updatedHeat"]').first().val();
        $.ajax({
            type: "POST",
            data: {
                mCollection: tdata,
                heatName: origname,
                updatedHeat: newname
            },
            url: '@Url.Action("ChangeHeatName","Home")',
            //url: "/Home/ChangeHeatName",
            success: function (result) { success(result); }
        });
    });


    function success(result) {

        $('#HeatNameDiv').dialog('close');
        //Ajax with problem
        $.ajax({
            type: "GET",
            url: '@Url.Action("ButtonsPartial","Home")',
            success: function (result2) { $("#ButtonsPartial").html(result2); }
        });
        $("#Partial_Chem_Analysis").html(result);
    }
});
</script>

事件处理程序绑定到原始按钮，该按钮被部分视图加载替换。之后，在您再次注册或第一次将click处理程序注册到父DOM元素之前，它没有处理程序。

$(document).ready(function () {
    // instead of this
    $('#ChangeHeatName').click(function (e) {
        ...
    });

    // do this
    $("body").on("click", "#ChangeHeatName", function(e) {
        ...
    });
});

尝试将"body"替换为静态DOM元素，尽可能靠近重新加载的部分。

$("#ButtonsPartial").on("click", "#ChangeHeatName", function(e) {
    ...
});
