在我的JavaScript中：

$(window).ready(function() {  
    $('#diff').html(diff);
});
var diff = calc("score","benchmark");
function calc(divID1,divID2) {
      div1 = document.getElementById(divID1);
      metric = div1.innerHTML;
      div2 = document.getElementById(divID2);
      benchmark = div2.innerHTML;
      c = Math.abs(a) - Math.abs(b);
// this is the difference here
      return String(c);  
};

我加载了D3和JQuery. div列中的数字是通过其他函数动态生成的,因此我无法对样式进行硬编码.
