请帮助引导到json数组的标题我的尝试：

(function (jQuery){
    var json = {
        "news": [{
            "img": "http://static3.www.net/img/300x300/2257740.jpeg",
            "title": "qwerty1",
            "url": "http://news.net.www.ru/newdata/adclick?ad=674134&bl=80802&ct=adpreview&st=16&in=YK2NFgCJu2FWSQoAjkkKAIhJCgBhSQoAfkkKAGJJCgA%3D&ag=19",
            "id": "674134"
        }, {
            "img": "http://static5.www.net/img/300x300/2257778.jpeg",
            "title": "qwerty2",
            "url": "http://news.net.www.ru/newdata/adclick?ad=674190&bl=80802&ct=adpreview&st=16&in=YK2NFgCJu2FWSQoAjkkKAIhJCgBhSQoAfkkKAGJJCgA%3D&ag=19",
            "id": "674190"
        }, {
            "img": "http://static3.www.net/img/300x300/2257776.jpeg",
            "title": "qwerty3",
            "url": "http://news.net.www.ru/newdata/adclick?ad=674184&bl=80802&ct=adpreview&st=16&in=YK2NFgCJu2FWSQoAjkkKAIhJCgBhSQoAfkkKAGJJCgA%3D&ag=19",
            "id": "674184"
        }, {
            "img": "http://static2.www.net/img/300x300/2257748.jpeg",
            "title": "qwerty4",
            "url": "http://news.net.www.ru/newdata/adclick?ad=674145&bl=80802&ct=adpreview&st=16&in=YK2NFgCJu2FWSQoAjkkKAIhJCgBhSQoAfkkKAGJJCgA%3D&ag=19",
            "id": "674145"
        }, {
            "img": "http://static1.www.net/img/300x300/2257766.jpeg",
            "title": "qwerty5",
            "url": "http://news.net.www.ru/newdata/adclick?ad=674174&bl=80802&ct=adpreview&st=16&in=YK2NFgCJu2FWSQoAjkkKAIhJCgBhSQoAfkkKAGJJCgA%3D&ag=19",
            "id": "674174"
        }, {
            "img": "http://static3.www.net/img/300x300/2257750.jpeg",
            "title": "qwerty6",
            "url": "http://news.net.www.ru/newdata/adclick?ad=674146&bl=80802&ct=adpreview&st=16&in=YK2NFgCJu2FWSQoAjkkKAIhJCgBhSQoAfkkKAGJJCgA%3D&ag=19",
            "id": "674146"
        }]
    }
    //console.log(JSON.parse(json));
    jQuery.each(JSON.parse(json), function(idx, obj) {
       alert(idx + '__' + obj.news.title);
    });
})($);

因此，控制台显示以下错误消息：

未捕获的SyntaxError：意外的令牌

您可以看到代码jsfiddle 的在线版本

将最后一位更改为-

    jQuery.each(json.news, function(idx, obj) {
           alert(idx + '__' + obj['title']);
        });
    })($);

您必须迭代json 的新闻

它已经被解析。因此JSON.parse将抛出一个错误。修复是JSON.parse(json)应该是简单的json。

希望这能有所帮助。
