我想显示“预测”

Answer 1

$.ajax({
   url: "http://weather.yahooapis.com/forecastjson?w=2295424",
   dataType: "json",
   success: function(data) {
      console.log( data.forecast[0].day );
      }
 });

在data.forecast [0] .day中，用你需要的任何属性替换“day”。

Answer 2

这应该是有效的：

console.debug("initYahooWeather starting");
    var urlYahooWeather = "http://weather.yahooapis.com/forecastjson?w=2295424";

    var urlFlickr = "http://weather.yahooapis.com/forecastjson?jsoncallback=?&w=2295424";
    jQuery.ajax({
        async: false,
        type: "POST",
        contentType: "application/json",
        dataType: "json",
        url: urlFlickr,
        success: function(data){
            console.dir(data);
            console.dir(data.forecast);
            // here you have to navigate the array 

        },
        error: function(msg){
            console.debug("error contacting JSON server side component...");
            console.debug(msg);
        }
    });

    console.debug("initYahooWeather stop");

我尝试了自己，但是使用jQuery 1.5我收到了一个解析错误：我不知道为什么，代码应该没问题。
