Cross-domain access agent Api-yahooapis

Do you have a problem with using AJAX to access some public-network APIs, but you don't want to set up your own proxy service, because sometimes I don't plan to involve any of the server's code, but the annoying browser's Sanyuan strategy blocks our Ajax calls.

For example I would like to visit a weather Restfull API if I go straight to get:

$.get ("http://m.weather.com.cn/data/101010100.html");

See this problem believe that everyone will not be unfamiliar, will naturally get the solution, but I really do not want to touch any service-side code, with Jsonp bar, but the server did not implement the contract.

It's time for me to introduce the main character Yahoo provides JSONP agent: HTTP://QUERY.YAHOOAPIS.COM/V1/PUBLIC/YQL

Implementing Cross-domain Access code is: http://jsfiddle.net/whitewolf/4UDpf/9/

Html:

<script type= "Text/javascript" src= "Http://ajax.cdnjs.com/ajax/libs/json2/20110223/json2.js" ></script >   
<center id= "Content" >   
</center>   
JS:   
$ (function () {   
    $.getjson ("http:// Query.yahooapis.com/v1/public/yql ", {   
    Q:" SELECT * from JSON where url= "http://m.weather.com.cn/data/101010100. HTML "",   
    Format: "JSON"   
}, function (data) {   
    var $content = $ ("#content")   
    if (data.query.results) {   
        $content. Text (json.stringify (data.query.results));   
    else {   
        $content. Text (' No such code: ' + code ';}});   

Effect:

Much needless to say, the principle of jsonp I believe that we are also very clear.
