如何将动态数据提供给静态jquery函数?

[英]How to feed dynamic data to static jquery function?

My source code is here below. 我的源代码在下面。 The chart it creates made by using chartist.js . 它使用chartist.js创建的图表。

<html>
<head>

    <link rel="stylesheet" href="chartist.min.css">

</head>
<body>
<h3>Chartist Test</h3>
<br>

<div id="ct-chart5" class="ct-perfect-fourth"></div>

<script src="chartist.min.js"></script>
<script src="jquery-2.1.4.min.js"></script>
<script>
    $(document).ready(function(){

        var data = {
            series: [5, 3, 4]
        };

        var sum = function(a, b) { return a + b };

        new Chartist.Pie('#ct-chart5', data, {
            labelInterpolationFnc: function(value) {
                return Math.round(value / data.series.reduce(sum) * 100) + '%';
            }
        });
    });
</script>

</body>
</html>

There is a var called data inside scripts tags below. 下面的脚本标签中有一个称为数据的变量。 But the thing is it has predefined values and chat is creating by those static values. 但事实是它具有预定义的值,而聊天是由这些静态值创建的。 How i can post some dynamic data into that variable? 我如何将一些动态数据发布到该变量中? lets say we have some data retrieving from mysql db. 可以说我们有一些从mysql db检索的数据。 i want to know how to feed those retrieving data into the predefined variable dynamically. 我想知道如何将那些检索数据动态地输入到预定义变量中。

I think you are talking about ajax calls, well you declare that variable globally make and ajax call, get dynamic data and update the variable. 我认为您是在谈论ajax调用,因此您可以全局声明该变量进行make和ajax调用,获取动态数据并更新该变量。

var data;
//some code

$.ajax({
  url: some_URL,
  data: some_data,
  dataType: some_datatype
  //other options,
  success:function(jqXHR){
    data=jqXHR;//assuming jqXHR is the dynamic data 
  }

})
