Answer 1

 $(document).ready(function(){ 
     var content = { 
     "data": { 
      "1":[ 
      { 
      "id":"3", 
      "title":"my title", 
      "content":"this is very basic sample content" 
      }, 
      { 
      "id":"4", 
      "title":"My sample title and text", 
      "content":"renewed by a licensing authority may be signed by such officer by the State Government.<p></p>" 
      } 
      ] 
     } 
     }; 

     alert(returnContent("basic")); 

     function returnContent(keyword) 
     { 
      var returnValue = null; 
      $.each(content.data, function(key, value){ 
       $.each(value, function(key2, value2){ 
        if(value2.content.toString().indexOf(keyword) != -1) 
        { 
         returnValue = value2.id.toString(); 
        } 
       }); 
      }); 
      return returnValue; 
     } 


    }); 

你只需要在returnContent（）函数中更改关键字你正在寻找
