任何人都可以帮我解决这个问题吗？我是编程新手，现在我遇到了这个问题。 我在最终生成的PDF中有超链接（从RTF转换为PDF）。当我尝试单击PDF中的链接时，它们在同一个iframe窗口中打开，而不是打开新窗口。
我希望在新窗口中打开我的超链接每当用户点击链接时。我正在使用最新版本的Aspose PDF。我尝试使用以下代码。
/*
causes a promise returning function not to be called
untill less than max are active
usage example:
max2 = throttle(2);
functions = [fn1,fn2,fn3...fn100];//functions returning promise
params = [param1,param2,param3...param100]
Promise.all(//even though a 100 promises are created, only 2 are active
functions.map(
(fn,index)=>
max2(fn)(params[index])
.then(...)
)
)
*/
const throttle =
(max) =>{
var que = [];
var running = 0;
const wait = function*(resolve,fn,arg){
return resolve(fn(arg));
};
const nextInQue = ()=>{
const it = que[0];
que=que.slice(1);
if(it){
it.next();
}
return true;
};
const queItem = (fn,arg)=>
new Promise(
(resolve,reject)=>que.push(wait(resolve,fn,arg))

const p = queItem(fn,arg)
.then(x=>nextInQue() && x)

running++;
if(running<=max){
nextInQue();

return p;
