javascript - how to deal with an if statement in a loop in AngularJS? -


मेरे पास यह 2 लूप हैं 

  & lt; आयन-सूची & gt; & Lt; ion-item ng- दोहराने = "श्रेणियों में श्रेणी" href = "#" & gt; {{Category.name}} {{category.id}} & lt; आयन-मद एनजी-दोहराने = "परीक्षणों में परीक्षण" href = "#" & gt; {{Test.name}} {{test.cat_id}} & lt; / आयन-आइटम & gt; & Lt; / आयन आइटम & gt; & Lt; / आयन सूची & gt;   
 मैं  परीक्षण करना चाहता हूं अगर (category.id === test.cat_id)  तब दूसरी सूची दिखाएं  
 मैं नहीं हूं  ngif  का उपयोग कैसे करें और कैसे करें, या अगर मुझे नियंत्रक में इसका ध्यान रखना चाहिए और मेरी ऑब्जेक्ट के लिए पहले से ही एक ऑब्जेक्ट फॉर्मेट किया गया है ..  
 कोई भी विचार?   
 
 
 अगर मैं सही ढंग से समझता हूं तो आप दूसरे एनजी-दोहराने को सशर्त रूप से दिखाना चाहते हैं। यदि ऐसा है तो आप इसका उपयोग कर सकते हैं:  
  & lt; आयन-सूची & gt; & Lt; ion-item ng- दोहराने = "श्रेणियों में श्रेणी" href = "#" & gt; {{Category.name}} {{category.id}} & lt; ion-item ng- दोहराने = "परीक्षणों में परीक्षण" href = "#" एनजी-अगर = "category.id === test.cat_id" & gt; {{Test.name}} {{test.cat_id}} & lt; / आयन-आइटम & gt; & Lt; / आयन आइटम & gt; & Lt; / आयन सूची & gt;   
 एक अन्य विकल्प इस तरह से एक फिल्टर का उपयोग करना होगा:  
  & lt; आयन-सूची & gt; & Lt; ion-item ng- दोहराने = "श्रेणियों में श्रेणी" href = "#" & gt; {{Category.name}} {{category.id}} & lt; आयन-मद एनजी-दोहराने = "परीक्षणों में परीक्षण: फ़िल्टर: {cat_id: category.id}" href = "#" एनजी-अगर = "श्रेणी। आईडी === test.cat_id "& gt; {{Test.name}} {{test.cat_id}} & lt; / आयन-आइटम & gt; & Lt; / आयन आइटम & gt; & Lt; / आयन सूची & gt;   
 मैं वास्तव में फ़िल्टर विकल्प सुझाएगा।
