通过window.open打开窗口，并在加载时使用window.print打印它
[英]Open window by window.open and print it with window.print on load
问题描述
I have some code like 
我有一些像
var windowObject = window.open('','windowObject','arguments...');
windowObject.document.write("<html><body onload="alert(1);window.print();alert(2);"><div>some html</div></body></html>");
The problem is that everything works except the window.print event (on ie, on firefox, it's working). 问题是，除了window.print事件（在firefox上，它正在工作）之外，所有其他东西都可以工作。
Is there a workaround? 有解决方法吗？
Thanks in advance, Gaurav 在此先感谢Gaurav

It's a quotes issue: the double quote after onload= ends the string being written to the document. 这是一个引号问题： onload=之后的双引号结束了写入文档的字符串。 Change the onload quotes to single quotes. 将onload报价更改为单引号。 You also need to add a call to the close() method of the document: 您还需要添加对文档的close()方法的调用：
var windowObject = window.open('','windowObject','arguments...');
windowObject.document.write("<html><body onload='alert(1);window.print();alert(2);'><div>some html</div></body></html>");
windowObject.document.close();

In this line, it appears that you are trying to use nested double quotes: 在此行中，您似乎正在尝试使用嵌套的双引号：
windowObject.document.write("<html><body onload="alert(1);window.print();alert(2);"><div>some html</div></body></html>");
You more likely want to do: 您更可能想做：
windowObject.document.write('<html><body onload="alert(1);window.print();alert(2);"><div>some html</div></body></html>');

Chrome is not allowing us to do print in newly opened window/tab. Chrome浏览器不允许我们在新打开的窗口/标签中进行打印。 You can achieve your requirement by adding a new html file like this <body onload="window.print()"><div>Some html</div></body> and replace your code with var windowObject = window.open('<path_to_your_new_html>','windowObject','arguments...'); 您可以通过添加一个新的HTML文件（例如<body onload="window.print()"><div>Some html</div></body>并将其代码替换为var windowObject = window.open('<path_to_your_new_html>','windowObject','arguments...');
