我不能讓我的if/else語句工作

Question

我想寫一個聲明，說如果＃process-description內有什麼東西顯示＃process-work其他的就隱藏它。

HTML

<div id="process-work"> 
     <h2 id="process-title">Process Work</h2> 
     <p id="process-description"></p> 
    </div> 

JS

  'zeckoshop' : { 
      'title' : 'zeckoShop', 
      'description' : 'An all-in-one ecommerce platform designed to seamlessly integrate with your business operations.', 
      'link' : 'http://darrenbachan.com/playground/zeckoshop/index.html', 
      'images': [ 
       '/images/zeckoshop/zeckoshop-1.jpg' 
      ], 
      'tags': [ 
       'Web Design', 
       'Web Development' 
      ], 
      'process-description' : 'An all-in-one ecommerce platform designed to seamlessly integrate with your business operations.', 
      'process-wireframes': [ 
       '/images/zeckoshop/zeckoshop-1.jpg' 
      ] 
     } 


if('#process-work') { 
      $('#process-description').html(projectData['process-description']).show(); 
     } else { 
      $('#process-work').hide(); 
     }

我認爲你正在尋找杉木這種變化中的代碼：

if($('#process-description').length) { 
      $('#process-description').html(projectData['process-description']).show(); 
     } else { 
      $('#process-work').hide(); 
     }
