Question

有人可以帮助您删除重复的代码。

我有四个仪表板作为样本我在这里提到了两个。

对于所有仪表板，同样的逻辑适用但是当我尝试使用css类根据条件应用css时它不起作用。

所以，我使用过id，它运行正常。

但是我必须重复并写四次相同的条件。这使得48以及其他一点都没有好处继续下去。请帮忙。

Answer 1

var dashboard = Array("#div-dashboard1","#div-dashboard2","#div-dashboard3", "#div-dashboard4");
var i;

for (i=0; i<dashboard.length; i++)
{
  if(dashboard[i]!=null)
  {
    var status1 =$(dashboard[i] + ' dashboard-table tbody tr:nth-child(2) td:nth-child(1)').text();
    var status2 =$(dashboard[i] + ' dashboard-table tbody tr:nth-child(2) td:nth-child(2)').text();
    var status3 =$(dashboard[i] + ' dashboard-table tbody tr:nth-child(4) td:nth-child(1)').text();
    var status4 =$(dashboard[i] + ' dashboard-table tbody tr:nth-child(4) td:nth-child(2)').text();
  }
}

希望你现在能得到一个想法..只写一次你的代码的其余部分
