Javascript在对象间循环时打印页面
我有一个网页，我正在使用它通过笔记本电脑上的firefox“打印到文件”打印机将“页面”数据打印成PDF文件。我调用的代码如下所示：Javascript在对象间循环时打印页面,javascript,firefox,printing,Javascript,Firefox,Printing,我有一个网页，我正在使用它通过笔记本电脑上的firefox“打印到文件”打印机将“页面”数据打印成PDF文件。我调用的代码如下所示： document.body.controls.cmdPrint.click = function () // Create a function that will be called when this object is clicked upon {if (parseInt(document
document.body.controls.cmdPrint.click = function () // Create a function that will be called when this object is clicked upon
{if (parseInt(document.body.controls.page.innerHTML) !== 0) // If we are not on the Front Cover
{return false;} // Function complete: Abnormal Termination
document.body.controls.style.pointerEvents = 'none'; // Lock down the controls so they cannot be interfered with
do // Do...
{window.print(); // Print this page
// document.body.sleep(); // Removed as this does not work as expected (see below...)
} while (document.body.controls.cmdNext.click()) // ...while we are able to advance.
document.body.controls.style.pointerEvents = ''; // Release the controls lockout
this.blur(); // Blur the focus
return true;}; // Function complete: Normal Termination
document.body.sleep = function (delay) // Create a new function
{delay = delay || 1; // Default to a delay of 1 second
var timestamp = new Date(); // Get current time
timestamp = new Date(timestamp.getTime() + (delay * 1000)); // Add in the delay (in seconds)
while (new Date() < timestamp) {} // While we are waiting for the delay, do nothing
return true;}; // Function complete: Normal Termination
document.body.sleep=function（delay）//创建一个新函数
{delay=delay | | 1；//默认延迟1秒
var timestamp=new Date（）；//获取当前时间
timestamp=新日期（timestamp.getTime（）+（delay*1000））；//添加延迟（秒）
while（new Date（）如果window.print（）在这种情况下确实返回了一个错误，我可以重新运行命令…在我的实验中，我发现了这个解决方法…这被认为是一个相当复杂的问题，但是在没有更优雅的解决方案的情况下，它是有效的
