我是JavaScript新手,我真的很喜欢jQuery而且讨厌编写一些繁琐的代码来完成简单的事情。
我目前正在尝试动态加载外部JS并执行它(与Google Translate API进行通信)。
示例代码会创建一个script
代码,设置其src
并将其附加到文档的head
以执行它:
var newScript = document.createElement('script');
newScript.type = 'text/javascript';
var sourceText = escape(document.getElementById("sourceText").innerHTML);
var source = 'https://www.googleapis.com/language/translate/v2?key=INSERT-YOUR-KEY&source=en&target=de&callback=translateText&q=' + sourceText;
newScript.src = source;
// When we add this script to the head, the request is sent off.
document.getElementsByTagName('head')[0].appendChild(newScript);
我想知道jQuery中是否有任何单行代码。

HeadJS 是为此类用途而设计的,这是一种简单且优化的方式来包含脚本这将有助于您确定。
