JavaScript沒有加載

Question

我試圖注入Chrome擴展一個javacript，但劇本的onload方法不叫......

var scriptURL = 'http://'+response.scriptUrl, 
    scriptTag = document.createElement('script'); 

scriptTag.type = 'text/javascript'; 
scriptTag.src = scriptURL; 

function onload() 
{ 
    alert('onload'); 
}; 

scriptTag.onload = onload; 
$('head').append(scriptTag); 

任何想法，爲什麼不提高了警惕？

請試試這個：在您的清單權限

var scriptURL = 'http://'+response.scriptUrl, 
    scriptTag = document.createElement('script'); 

scriptTag.type = 'text/javascript'; 
scriptTag.src = scriptURL; 

function onload() 
{ 
    alert('onload'); 
}; 

scriptTag.onload = onload; 
var head = document.getElementsByTagName('head')[0]; 
head.appendChild(scriptTag);
