Question

我无法使用jquery和pug将变量传入Highcharts函数，这是我需要的，以便串行设置数据。我在index.js文件中创建了一个名为getData的函数，该函数以下列格式输出信息

{＆＃39;健康与人类服务＆＃39;：1788131，＆＃39;人力资源＆＃39;：107285，＆＃39;公共部门部门＆＃39;：228969，＆＃39;财政部＆＃39;：27500，＆＃39;文化服务＆＃39;：23600，＆＃39; MARIN COUNTY PARKS＆＃39;：28380，＆＃39; MARIN COUNTY FIRE＆＃39;：9600，＆＃39; MARIN COUNTY FREE LIBRARY＆＃39;：2672，提示：0，＆＃39;农业加权措施＆＃39;：20000}

然后我将对象分配给变量，然后将其推入数组。我的问题是当我将它传递给函数时访问变量data_output2。我不太了解Javascript，所以这真的是一个黑客工作。任何帮助都会非常感激！

index.pug文件

        } else {
          // data is already parsed as JSON:
        }
        //do the calculation to return sum value of one department with one time

         var data_output = getData(data,6, 2016);
         var array = [];
         array.push(data_output);
         console.log(data_output);
         console.log(array);

        //uses the templating engine pug to display information
        res.render('index', { title: 'Hey', message: 'Hello there!', message2:responseText, data_output: data_output, data_output2: array });
    });

})

Answer 1

试试这个剧本。

var data_output2 =!{data_output2}
$(function(){
  //your code stuff
})
