我怎樣才能讓冰API JSON例如工作

的例子，我可以得到alert0但這個例子不調用回調。

     } 

     errorsListItem.innerHTML += "<br />"; 
    } 
} 

</script> 

</head> 
<body onload="Search()"> 
Bing api test 
<div id="output"></div> 
</body> 
<script id="searchCallback" type="text/javascript" src=""></script> 

</html>

如果我手動請求requestStr我能得到迴應：

if(typeof SearchCompleted == 'function') SearchCompleted({"SearchResponse":{"Version":"2.0","Query":{"SearchTerms":"msdn blogs"},"Web":{"Total":2,"Offset":0,"Results":[{"Title":"MSDN Blogs","Description":"Integrated blog from the Microsoft Developer Network.","Url":"http:\/\/blogs.msdn.com\/","DisplayUrl":"blogs.msdn.com","DateTime":"2012-01-09T22:59:00Z"},{"Title":"Remote Desktop Services (Terminal Services) Team Blog - Site Home ...","Description":"All postings, articles, and other content on this blog are provided 」AS IS」 with with no warranties, and confer no rights. Any code, demo, or sample on this blog ...","Url":"http:\/\/blogs.msdn.com\/b\/rds\/","DisplayUrl":"blogs.msdn.com\/b\/rds","DateTime":"2012-01-11T17:59:00Z"}]}}} /* pageview_candidate */);

我不能看到的要求如何得到執行後，得到的投入「searchCallback」 SRC

我我試過了IE9 FF和Chrome，都不工作:(

如果你只是改變一個現有元素的來源，請求不會啓動，請嘗試以下操作，換行：

var requestScript = document.getElementById("searchCallback"); 
requestScript.src = requestStr;

有了：

var commScript = document.createElement("script"); 
commScript.src = requestStr; 
commScript.type = "text/javascript"; 
commScript.charset = "UTF-8"; 
//Find the head element such that we can append our communication script 
if(document.head) 
{ 
    head = document.head; 
} 
else if(document.getElementsByTagName) 
{ 
    head = document.getElementsByTagName('head')[0]; 
} 
else 
{ 
    document.write("An error occured"); 
} 
head.appendChild(commScript);
