我有一个JSON内容。从那里我需要搜索并获取搜索关键字的ID。

关键字：＆＃34;权威＆＃34; =＆gt;我希望id为4

关键字：＆＃34;基本＆＃34; =＆gt;我希望得到id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>"
    }
  ]
 }
}

        $(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
