我想將“txtDATE”文本框中的文本放入變量 press_date 中。當(dāng)前的 AJAX 帖子運(yùn)行良好。（除了它是靜態(tài)的，我想要變量）。我整天都在尋找答案并嘗試一切。任何幫助表示贊賞。<td>     <asp:TextBox ID="txtDATE" runat="server" AutoPostBack="true" Width="75px" ></asp:TextBox></td>var press = "'1000'";var press_date = "'2020-08-01'";$.ajax({ type: "POST", url: "1000TIOT.aspx/GetChartData", data: "{ press: " + press +  ", press_date: " + press_date + " }", contentType: "application/json; charset=utf-8", dataType: "json", success: function (r) {     var data1 = google.visualization.arrayToDataTable(r.d);     var chart = new google.visualization.BarChart($("#chart")[0]);     chart.draw(data1, options); }, failure: function (r) {     alert(r.d); }, error: function (r) {     alert(r.d); }});
