【问题描述】：

如何从 JSON 格式搜索关键字。使用 jquery 或 javascript

我有一个 JSON 内容。从中我需要搜索并获取搜索关键字的 id。

Keyword: "authority" => 我想得到 id 为 4

Keyword: "basic" => 我想把 id 设为 3

 "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>"
    
  ]

【参考方案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;
        


    );

您只需在 returnContent() 函数中更改您要查找的关键字
