如何使用amchary URL传递javascript变量

Question

 function custom(vall)
 {

   var chart;


  // create chart
   AmCharts.ready(function() {
    alert(vall);
  // load the data
 var chartData =   AmCharts.loadJSON('http://localhost/vivek/daydata.php?data=vall');                                                   

  // SERIAL CHART    
 chart = new AmCharts.AmSerialChart();
 chart.pathToImages = "http://www.amcharts.com/lib/images/";
 chart.dataProvider = chartData;
chart.categoryField = "hrs";
 chart.theme = "none";
 chart.type = "serial";
}

var chartData = AmCharts.loadJSON（'http://localhost/vivek/daydata.php?date=vall'）; 我希望在这个网址中传递vall，但它不是值，在url中只显示vall变量而不是值。

Answer 1

我认为下面应该适合你。取出val变量形式的引号。

AmCharts.loadJSON（ “http://localhost/vivek/daydata.php?data=” +瓦尔）;
