if else 語句在反應中顯示圖標

Question

我需要根據data.id值顯示圖標，（示例圖標顯示也在注釋代碼中。你能建議我如何根據data.id值給出一個else if條件來顯示這個圖標嗎？

Answer 1

更新

為了你的改變。 您可以將我的 function 與此一起使用。 它將為您返回一個圖標組件。

return(
    { 
      id: data.id, 
      name: data.name, 
      icon: loadIcon(data),
      childs: data.childs
    }
  )

舊答案

你可以試試這個方法

function loadIcon(data) {
   const icons = {
      ['1']: <Icons2.frock01 />,
      ['2']: <Icons2.frock02 />,
      ['3']: <Icons2.frock03 />,
      ['4']: <Icons2.frock04 />,
   }
   return icons[data.id]
}

用法

<>{loadIcon(data)}</>

Answer 2

那么，你可以做的是將你的item.icon div放在條件渲染中，如下所示。 並使用ternary operator

{data.id === '1' ? 
  (
    <div className="col-span-1">{data.icon}</div>
  ) 
  : 
  (
    // Anything else you want to render
  )   
}
