我觉得应该有这样的服务,但是找不到,所以来问一下:有没有直接把 ajax 才能读取的 json 转换成可以直接引用在网页中的的?

    这是一个创建于 3595 天前的主题,其中的信息可能已经有所发展或是发生改变。

    类似于把

    {"programmers":[{"firstName":"Brett","lastName":"McLaughlin","email":"aaaa"},
    {"firstName":"Jason","lastName":"Hunter","email":"bbbb"},
    {"firstName":"Elliotte","lastName":"Harold","email":"cccc"}
    ],
    "authors":[
    {"firstName":"Isaac","lastName":"Asimov","genre":"sciencefiction"},
    {"firstName":"Tad","lastName":"Williams","genre":"fantasy"},
    {"firstName":"Frank","lastName":"Peretti","genre":"christianfiction"}
    ],
    "musicians":[
    {"firstName":"Eric","lastName":"Clapton","instrument":"guitar"},
    {"firstName":"Sergei","lastName":"Rachmaninoff","instrument":"piano"}
    ]}

    变成这种的

    var people={"programmers":[{"firstName":"Brett","lastName":"McLaughlin","email":"aaaa"},
    {"firstName":"Jason","lastName":"Hunter","email":"bbbb"},
    {"firstName":"Elliotte","lastName":"Harold","email":"cccc"}
    ],
    "authors":[
    {"firstName":"Isaac","lastName":"Asimov","genre":"sciencefiction"},
    {"firstName":"Tad","lastName":"Williams","genre":"fantasy"},
    {"firstName":"Frank","lastName":"Peretti","genre":"christianfiction"}
    ],
    "musicians":[
    {"firstName":"Eric","lastName":"Clapton","instrument":"guitar"},
    {"firstName":"Sergei","lastName":"Rachmaninoff","instrument":"piano"}
    ]}

    这样就不需要考虑跨域问题,直接在dom里引用,然后在js中获取。
    对于只有静态的网页帮助很大

    @mcfog 已感谢。边用边学的中学生表示,虽然见过这个,但是不知道是可以跨域的。

    var str="{a:1,b:2}";
    var json=(new Function("return "+str))();
    console.log(json);

    要么就用JSONP

    jsonp需要服务器支持,不能达到我的要求,但是找到了“jsonp代理”,可用。
    附上我修改后的雅虎代理使用:
    src = 'http://www.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1&mkt=zh-CN'

    $.getJSON("http://query.yahooapis.com/v1/public/yql", {
    q: 'select * from json where url="' + src + '"',
    format: "json"
    },
    function(data) {
    console.log(data.query.results.json.images)
    })
