차트를 처리하고 키 매개 변수에 textbox, button을 처리 할 사람이 있습니다.json 데이터를 검색 한 후에 자바 스크립트가 채워지지 않습니다
<asp:TextBox ID="txtDate" CssClass="form-control" runat="server"></asp:TextBox>
<asp:TextBox ID="txtSearchTerm" runat="server" Width="200px" class="form-control" placeholder="Terminal Number" spellcheck="false"></asp:TextBox>
<asp:Button ID="btnSearchTerm" runat="server" Text="Search" class="btn btn-primary" />
나는 데이터베이스에서 데이터를 쿼리 뒤에 코드를 작성 : 코드 위
<WebMethod()>
Public Shared Function GetChart(ByVal Tdate As String, ByVal Term As String) As List(Of Object)
Dim BizFunc As New BizFunction.UtilFormat
Dim chartData As New List(Of Object)()
Dim TabName As String = "TA" & Tdate
Dim TodayDate As String = BizFunc.Date2YYMM(Today.Date)
Dim labels As New List(Of String)()
If Tdate = Mid(TodayDate, 1, 4) Then
TabName = "(select * from " & TabName & " union all select * from TA" & TodayDate & ") TA "
End If
Dim query As String = "WITH t1 AS (SELECT dt,DATEADD(MONTH,DATEDIFF(MONTH,'1900-01-01',dt),'1900-01-01') AS firstInMonth,DATEADD(DAY,-1,DATEADD(MONTH,DATEDIFF(MONTH,'1900-01-01',dt)+1,'1900-01-01')) AS lastInMonth,amount " &
" FROM(SELECT CONVERT(DATE, tran_date) AS dt,COUNT(*) AS AMOUNT FROM " & TabName & " WHERE TERM Like '%" & Term.PadRight(16, " ") & "%' and (TRANS = '05' or TRANS = '06') GROUP BY TRAN_DATE) AS st " &
"Group BY dt, amount), " &
"Calendar " &
" AS (SELECT DISTINCT DATEADD(DAY, c.number,t1.firstInMonth) AS d FROM t1 JOIN master..spt_values AS c On type = 'P' AND DATEADD(DAY,c.number,t1.firstInMonth) BETWEEN t1.firstInMonth AND t1.lastInMonth) " &
" Select DatePart(dd, d) Date, Case When amount Is NULL Then 0 Else amount End As amount FROM calendar As c LEFT JOIN t1 On t1.dt = c.d;"
Dim dtbal As DataTable = GetData(query)
Dim series1 As New List(Of Integer)()
For Each row As DataRow In dtbal.Rows
labels.Add(Convert.ToString(row("Date")))
Next
chartData.Add(labels)
For Each row As DataRow In dtbal.Rows
series1.Add(Convert.ToInt32(row("AMOUNT")))
Next
chartData.Add(series1)
Return chartData
End Function
완벽하게 노력하고 있습니다.
문제는 Javascript에 : 나는 모든 행에 경고하려고이 $.Ajax에 붙어
$(function() {
$("[id*=btnSearchTerm]").click(function() {
LoadChart();
});
});
function LoadChart() {
var tdate = $("[id*=txtdate]").val();
var term = $("[id*=txtSearchTerm]").val();
$.ajax({
type: "POST",
url: "MonthlyBalancing.aspx/GetChart",
data: "{TDate: '" + tdate + "', term: '" + term + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (r) {
var labels = r.d[0];
var series1 = r.d[1];
var data = {
labels: labels,
datasets: [
{
label: "Dataset1",
backgroundColor: "rgba(38, 185, 154, 0.31)",
borderColor: "rgba(38, 185, 154, 0.7)",
pointBorderColor: "rgba(38, 185, 154, 0.7)",
pointBackgroundColor: "rgba(38, 185, 154, 0.7)",
pointHoverBackgroundColor: "#fff",
pointHoverBorderColor: "rgba(220,220,220,1)",
pointBorderWidth: 1,
data: series1
}]
};
$("#LineSumbalance").html("");
var canvas = document.createElement('canvas');
$("#LineSumbalance")[0].appendChild(canvas);
//Fix for IE 8
if ($.browser.msie && $.browser.version == "8.0") {
G_vmlCanvasManager.initElement(canvas);
}
var ctx = canvas.getContext('2d');
var lineChart = new Chart(ctx).Line(data, {
bezierCurve: false
});
},
failure: function (response) {
alert('There was an error.');
}
});
}
. 그것은 실패조차도 실행하지 않습니다.
