QT script调用JS立即执行函数

[liuandsky]

问题是这样的，我在QT里读取本地一个JS文件，需要执行并得到结果，但是看了很久这个JS文件都不知道该怎么调用，网上查找得知这个JS文件是个立即执行文件，我尝试了很多方式都不行，所以我在代码里该怎么写呢？
这是我现在写的方式，但是不成功：
QScriptEngine engine;
QScriptValue js = engine.evaluate(contents); //contents为js文件内容
QScriptValue func = engine.globalObject().property("pa");
QString result = func.call(QScriptValue(), args).toString();


下面是JS文件全部内容：
(function() {
function Pa() {
if ( - 1 == G("RAIL_EXPIRATION")) for (var a = 0; 10 > a; a++) H(function() { (new ja).getFingerPrint()
},
20 + 2E3 * Math.pow(a, 2));
else(new ja).getFingerPrint();
H(function() {
r.setInterval(function() { (new ja).getFingerPrint()
},
3E5)
},
3E5)
}

这个几乎不会成功 因为有很多的函数 是只存在于 浏览器的 比如那些 DOM 操作
