var iframe = document.createElement('iframe');iframe.hidden = true;iframe.src = "jianshu://notes/" + Maleskine.note.slug;//喚起appdocument.body.appendChild(iframe);var startTime = new Date();window.setTimeout(function() { 600 > new Date() - startTime && (Maleskine.showDownloadHelp())//跳轉下載}, 400) window.setTimeout(function() { 600 > new Date() - startTime && (Maleskine.showDownloadHelp()) }, 400)特別這一段是怎樣工作的呢？
這段代碼中iframe與setTimeout是如何實現判斷APP是否喚起的？
