Question

我使用库d3.js创建了一个交互式树形图，我现在尝试添加这样的功能，无论何时单击某个节点，它都会将您重定向到该元素的页面（对应于一个节点）

以前，我只有类型＆＃34;产品＆＃34;并使用了这个功能：

function clack(d) {
  if (d.name != "Product Catalog"){
    window.location.href = "http://1XX.XX.1.XX/App/redirect?entity_type=product&field_name=itemId&field_value=" + d.id;
  }
}

它完美无缺！

然而，我现在添加了另一种名为＆＃34; risk_coverages＆＃34;这是产品的子项，但希望被重定向到这两个元素的路径。

实际上，我的新实体类型的功能＆＃34; risk_coverages＆＃34;只会是：

 function clack(d) {
  if (d.name != "Product Catalog"){
    window.location.href = "http://1XX.XX.1.XX/App/redirect?entity_type=risk_coverages&field_name=itemId&field_value=" + d.id;
  }
}

我的问题是我不知道如何制定条件：

IF＆＃34; entity_type = product＆amp; field_name = itemId＆amp; field_value =＆＃34; + d.id，然后将我重定向到我的产品页面

OR

IF＆＃34; entity_type = risk_coverages＆amp; field_name = itemId＆amp; field_value =＆＃34; + d.id，然后将我重定向到我的风险承保页面

在英语中，它将是：

如果它是产品，请查找此产品并显示其页面

OR

如果它是风险承保范围，那么请查找此风险承保范围并显示其页面

我希望我足够清楚。

非常感谢任何帮助!!

非常感谢，

使用＆＃34; window.location.href＆＃34;添加两个可能的路径;在相同的条件下
