方法一:缺陷:打开的新链接非同源时,不生效
const newWindow = window.open(url)newWindow.onload = () => {newWindow.document.title = fileInfo.appendixName}
方法二缺陷:h5的android端不支持
openWindow (url, title) {const newWindow = window.open('about:blank', title);newWindow.document.title = title;let iframe = document.createElement('iframe');iframe.src = url;iframe.style.width = '100%';iframe.style.height = '100vh';iframe.style.margin = '0';iframe.style.padding = '0';iframe.style.overflow = 'hidden';iframe.style.border = 'none';newWindow.document.body.style.margin = '0';newWindow.document.body.appendChild(iframe);},this.openWindow(url, title)
