I guess, at first, you should output that variable into your HTML/JavaScript code, something like this:
我想，首先，您应该将该变量输出到您的 HTML/JavaScript 代码中，如下所示：
<script type="text/javascript">
var myvariable = "${myvariable}";
function myfunction(){
alert(myvariable);
}

You can use FreeMarker code in JavaScript straight away. Here's a sample code where FreeMarker supplies the data of a Morris.js chart. I think you'll get the idea.
您可以立即在 JavaScript 中使用 FreeMarker 代码。这是 FreeMarker 提供 Morris.js 图表数据的示例代码。我想你会明白的。
new Morris.Area({
element: 'searchTrend',
resize: true,
data: [
<#list searchCount as sc>
{day: '${sc.date!?string("yyyy-MM-dd")}', count: ${sc.searches}} <#sep>,
</#list>
],
xkey: 'day',
ykeys: ['count'],
labels: ['Count'],
xLabelFormat: function (x) { return x.getDate(); }
});
