Question

我这里有问题。我试图在高图实例中显示我的数据。对数据的查询包含 WHERE 子句。因为 where 子句我需要序列化需要进入我的PHP的数据，然后调用函数将数据显示到高图。我尝试了许多代码，但我的代码都没有为它工作。

我使用此代码来调用数据。有关获取值的表单的信息，我正在使用#form_input10

$(function () {
			var chart;
			$(document).on('click','#display',function(e) {
				var json = $("#form_input10").serialize();
				$.getJSON("../php/termocouple/line_termocouple.php", function(json) {
				
					chart = new Highcharts.Chart({
						chart: {
							renderTo: 'chart1',
							type: 'line'
							
						},
						exporting: { 
						enabled: false 
						},
						title: {
							text: 'Termocouple Graph Result'
							
						},
						subtitle: {
							text: ''
						
						},
						xAxis: {
							title: {
								text: 'Sensor'
							},
							categories: ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12']
						},
						yAxis: {
							title: {
								text: 'Temperature (°C)'
							},
							plotLines: [{
								value: 0,
								width: 1,
								color: '#808080'
							}]
						},
						tooltip: {
							formatter: function() {
									return '<b>'+ this.series.name +'</b><br/>'+
									this.x +': '+ this.y;
							}
						},
						legend: {
							layout: 'vertical',
							align: 'right',
							verticalAlign: 'top',
							x: -10,
							y: 120,
							borderWidth: 0
						},
						exporting: { 
						enabled: false 
						},
						series: json
					});
				});
			
			});
	
		});

我也尝试使用此代码，但我的数据仍未显示

$(function () {
			
			$(document).on('click','#display',function(e) {
				var data = $("#form_input10").serialize();
	  
       			$.ajax({

				dataType: 'JSON',
                url: "../php/termocouple/line_termocouple1.php",
                success: function(data){					
  				var list = JSON.parse(data);
				chart = new Highcharts.Chart({

$.getJSON()执行 GET 请求。要获取 POST 数据，请使用$.post()。

$.post("../php/termocouple/line_termocouple.php", json, function(json) {

同样，第二个代码段正在发送 GET 请求。要让它发送 POST 请求，请更改类型：

$.ajax({
    data: data,
    type: "POST",

我上周碰巧看了your other similar question，并准备展示它的运作情况。我为它保留了我的试验性PHP代码，并且可以显示上述变化的示例。看看this PHPFiddle。请注意：

将PHP代码简化为对array_map()的2次调用，以生成数字。我无权访问您的数据库，因此无法运行查询。
AJAX请求的URL已更新为`因为PHPFiddle只允许一个PHP文件
我在调用json_encode()之前添加了行header('Content-Type: application/json');，以确保jQuery代码将响应解释为JSON。

单击标有运行 - F9 的按钮以查看该页面，然后单击标有“显示数据”的按钮以触发表单序列化和AJAX请求。

下面是我在Firefox中打开网络选项卡并观察带有参数的POST请求（即 POST 数据）的屏幕截图。

如何使用按钮onclick从表单序列化数据显示高清数据？
