Question

我想将PHP查询数据库中的值插入.js echart页面中，如何传输这些数据，以便可以绘制图形？

我要计算等待的请求，然后传输到负责创建图的Javascript

我是一名编程初学者，我喜欢学习，我不是专业人士，也没有在学校学习。感谢您的所有帮助和理解。

phpquery.php：

<?php
\\query get data from bd

$path = $_SERVER['DOCUMENT_ROOT'] . '\dist\includes\\';
$file = $path . 'db.connect.php';
include($file);
$tec=$_SESSION['nome'];
$permi = $_SESSION['permisson'];
if($permi == "Técnico"){ $sql = "SELECT * FROM npedido WHERE estado = 'Novo' and (tec1 ='$tec' or tec2 ='$tec')";}else if($permi == "Administrador"){ $sql = "SELECT * FROM npedido WHERE estado = 'Novo'";}
    $stmt = sqlsrv_query( $conn, $sql);
	 $contador_pedidos_novos = 0;
    while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_NUMERIC) ) {
       $contador_pedidos_novos++;
    }

     
    
    ?>

我想将结果放入值内：“ {value:**<--mydata-->**, name:'New'}”

/*****E-Charts function start*****/
var echartsConfig = function() { 
	

	if( $('#e_chart_3').length > 0 ){

		var option3 = {

				},
			],
			animationType: 'scale',
			animationEasing: 'elasticOut',
			animationDelay: function (idx) {
				return Math.random() * 1000;
			}	
		};
		eChart_3.setOption(option3);
		eChart_3.resize();
	}
}

答案是在php文件中创建变量，然后从查询中获取数据内容，然后添加此行。

<script type="text/javascript">var teste = "<?= $teste ?>";</script>

在.js文件上，只需将变量名称添加到数据字段中即可：

<--other code-->
data:[
      {value:25, name:teste},
      <--other code-->
