试图用Jquery.parseJson解析......第二部分

标签: jquery json parsing

我最近在这里发布了关于Jquery.parseJson的内容。现在,我已成为我成就的第二部分。我让这个脚本使用stackoverflow用户帮助。

<input type="text" id="query" /><button>search</button><br />
<div id="results">

</div>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function(){
        $('button').click(function(){
            $("#query").val(); // Do nothing with this value
            var json = eval('({"name":"John"})');
            $("#results").append('<p>' + json.name + '</p>');
            // $.getJSON('{"name":"John"}',function(json){
            //     $.each(json.results,function(i,obj){
            //         $("#results").append('<p>' + obj.name + '</p>');
            //     });
            // });
        });
    });

现在我已经有了这个代码了,我已经构建了一个真正的JSON来解析,这里是:

["http:\/\/guimaraes-braga.olx.pt\/seat-leon-1-9tdi-sport-111cv-iid-148286318",
 {"1":"http:\/\/static04.olx-st.com\/images\/v4\/logos\/logo-default.png"},
     {"2":"http:\/\/images03.olx.pt\/ui\/10\/71\/18\/t_1292857323_148286318_1.jpg"},
 {"3":"http:\/\/images04.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_2.jpg"},
        {"4":"http:\/\/images04.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_3.jpg"},
 {"5":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_4.jpg"},
 {"6":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_5.jpg"},
 {"7":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_6.jpg"},
 {"8":"http:\/\/images03.olx.pt\/ui\/10\/71\/18\/t_1292857323_148286318_1.jpg"},
 {"9":"http:\/\/images04.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_2.jpg"},
 {"10":"http:\/\/images04.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_3.jpg"},
 {"11":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_4.jpg"},
 {"12":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_5.jpg"},
 {"13":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_6.jpg"},
 {"14":"http:\/\/images01.olx.com\/images\/spinner.gif"},
 {"15":"http:\/\/images01.olx.pt\/ui\/10\/71\/18\/1292886514_148286318_1-Fotos-de--SEAT-LEON-19TDI-SPORT-111CV.jpg"},
 {"16":""}]

上面的这个JSON包含图像的URL,我试图像第一个脚本一样传递这个JSON,但它不起作用......下面的代码中有更多细节。

<?php $json = new img_json_output(); ?>
<?php $data = $json->get_img_tags_as_json($json->get_page('http://guimaraes-braga.olx.pt/seat-leon-1-9tdi-sport-111cv-iid-148286318')); ?>

<input type="text" id="query" /><button>search</button><br />
<div id="results">

</div>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function(){
        $('button').click(function(){
            $("#query").val(); // Do nothing with this value
            var json = eval(<?php echo $data; ?>);
            $("#results").append('<p>' + json.1 + '</p>');
        });
    });
</script>

PHP变量$ data返回JSON。

如何让它发挥作用?问题出在我的JSON格式上吗?

这不是你问题的真正答案,只是一个建议。你试过json2库吗?它非常好并且处理解析和序列化json。这是一个链接json.org。当缩小时,它是2.5k,因此没有多少额外的开销。

答案 1 :(得分:0)

        var json = eval( "(" + '<?php echo $data; ?>' + ")" );

尝试检查:
1. JSON字符串不包含回车符 2.方法链。最外面的结构是一个数组。它应该是json [0]或json [1] [“1”]。

以下脚本适合我。

 <body>
     <input type="text" id="query" /><button>search</button><br />
     <div id="results">

     </div>

     <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
     <script type="text/javascript">
         $(document).ready(function(){
             $('button').click(function(){
                 var json = eval('(' + '["http:\/\/guimaraes-braga.olx.pt\/seat-leon-1-9tdi-sport-111cv-iid-148286318", {"1":"http:\/\/static04.olx-st.com\/images\/v4\/logos\/logo-default.png"}, {"2":"http:\/\/images03.olx.pt\/ui\/10\/71\/18\/t_1292857323_148286318_1.jpg"}, {"3":"http:\/\/images04.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_2.jpg"}, {"4":"http:\/\/images04.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_3.jpg"}, {"5":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_4.jpg"}, {"6":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_5.jpg"}, {"7":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_6.jpg"}, {"8":"http:\/\/images03.olx.pt\/ui\/10\/71\/18\/t_1292857323_148286318_1.jpg"}, {"9":"http:\/\/images04.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_2.jpg"}, {"10":"http:\/\/images04.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_3.jpg"}, {"11":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_4.jpg"}, {"12":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_5.jpg"}, {"13":"http:\/\/images02.olx.pt\/ui\/10\/71\/18\/t_1292886514_148286318_6.jpg"}, {"14":"http:\/\/images01.olx.com\/images\/spinner.gif"}, {"15":"http:\/\/images01.olx.pt\/ui\/10\/71\/18\/1292886514_148286318_1-Fotos-de--SEAT-LEON-19TDI-SPORT-111CV.jpg"}, {"16":""}]' + ')');
                 for (var i=1; i<json.length; i++){
                     $("#results").append('<p>' + json[i][i] + '</p>');
                 }
             });
         });
     </script>

 </body>

答案 2 :(得分:0)

var json = eval(<?php echo $data; ?>); // Will not work

摆脱eval功能。在此上下文中,JSON是有效的JavaScript,它将服务器生成的JavaScript代码分配给变量。然后它应该工作正常:

var json = <?php echo $data; ?>; // Works fine

您确实需要修复此行:

$("#results").append('<p>' + json.1 + '</p>');

尝试json[1]["1"]而不是json.1
