我正在编写一个程序，其中当日期发生更改时会创建一个表。但这里的问题是，首先在选择日期时创建表，但是当我开始更改日期时，表不会创建，并且控制台中没有错误。下面是我的代码。

table.jsp

<html>
<head>
<link rel="stylesheet"
    href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<script src="jbPivot.min.js"></script>
<link rel="stylesheet" href="jbPivot.css">


</head>
<body>
    <marquee>
        <h1>This is an example of ajax</h1>
    </marquee>

    <p>
        Date: <input type="text" id="startDatePicker">
    </p>
    <p>
        Date: <input type="text" id="endDatePicker">
    </p>
    <span id="somediv"> <span id="err">Select Correct Dates</span>
    </span>
    <script type="text/javascript" src="tableGenerator.js"></script>

</body>
</html>

tableGenerator.js

var startDate = $("#startDatePicker").datepicker({
    dateFormat : 'yy-mm-dd',
    onClose : function(selectedDate) {
        $("#endDatePicker").datepicker("option", "minDate", selectedDate);
    }
});
var endDate = $("#endDatePicker").datepicker({
    dateFormat : 'yy-mm-dd',
    onClose : function(selectedDate) {
        $("#startDatePicker").datepicker("option", "maxDate", selectedDate);
    }
});
$(document).on('change', '#startDatePicker,#endDatePicker', function() {
    $('#somediv > table').remove();
    $.getJSON('Controller', {
        'startDate' : startDate.val(),
        'endDate' : endDate.val()
    }, function(searchList) {
        console.log(JSON.stringify(searchList));
        if (searchList.length < 1) {
            $('#err').show();
            $('#err').text("No Records found in Specified Dates");
        } else {
            $("#somediv").jbPivot({
                fields : {
                    caseOwner : {
                        field : 'caseOwner',
                        sort : "asc",
                        showAll : true,
                        agregateType : "distinct"
                    },
                    finalStatus : {
                        field : 'finalStatus',
                        sort : "asc",
                        showAll : false,
                        agregateType : "distinct"
                    },
                    status : {
                        field : 'status',
                        sort : "asc",
                        showAll : false,
                        agregateType : "distinct"
                    },
                    Count : {
                        agregateType : "count",
                        groupType : "none"
                    },
                },
                xfields : [ "caseOwner" ],
                yfields : [ "finalStatus" ],
                statfields : [ "status" ],
                zfields : [ "Count" ],
                data : searchList
            });

        }

    });
});

                    userBean.setFinalStatus(rs.getString("Final Status"));
                    list.add(userBean);
                } while (rs.next());
            }
        } catch (Exception e) {
            System.out.println(e + " DAO Error");
        }
        return list;
    }
}

请让我知道我该怎么做。我应该在不刷新页面的情况下获取数据。即，一旦我更改日期，更改就会反射(reflect)出来。

谢谢

最佳答案

我在您的代码中看到的问题是您总是尝试初始化 somediv 元素上的数据透视表小部件。我认为如果您尝试使用不同的数据一次又一次地在同一元素上初始化小部件，则数据透视表小部件将不会更新表。根据文档here ，如果您想替换表数据，您应该获取对数据透视表数据对象的引用，并使用新列表调用 insertRecords()。

 var $data = $("#pivot1").data('jbPivot');
 $data.reset();
 $data.insertRecords([--your-new--array--]);

这是一个示例 pen行动中。
