Question

我在加载jquery datetime picker时遇到问题。我使用了bootstrap以及nv.d3图表。请帮助我。

这里当我点击输入然后日历没有显示以及它在javascript中的更改功能由于某些问题而无效。请帮我显示该日历。

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">

 </div>
 </asp:Content>

My javascript code

window.onload = nv.addGraph;
var chart = nv.models.pieChart();
var startDate;
var endDate;

$('#dp2').datepicker().on('changeDate', function (ev) {    
    $("#chart svg").html('');
    nv.addGraph();
});

$('#dp1').datepicker().on('changeDate', function (ev) {    
    $("#chart svg").html('');
    nv.addGraph();
});

nv.addGraph(function () {

    var startDate = $("#dp2 input").val();
    var endDate = $("#dp1 input").val();

    $.ajax({
        type: "POST",
        url: ("Default.aspx/GetData"),
        data: "{startDate:'" + startDate + "',endDate:'" + endDate + "'}",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (result) {


            var data = $.parseJSON(result.d);
           // console.log(data);


            chart.x(function (d) { return d.label });
            chart.y(function (d) { return d.value });
            chart.showLabels(false);


            d3.select("#chart svg")
            .datum(data)
            .transition().duration(1200)
            .call(chart);

            return chart;

        },
        error: function (xhr, txt, err) {
            alert("error connecting to data: " + txt);
        }

    });
});
