Javascript打印功能如何工作？可以使用javascript创建文档并将其打印出来吗？ [英] How does the Javascript print function work? Can I create a document using javascript and print it off?
问题描述
就像您可以将HTML / xml作为JavaScript对象一样，可以执行类似的操作：
var name =Matt;
var htmlDocumentToPrint =< html>< body>< div style ='width：300px; height：20px; background-color：＃000; text-align：center;'>我的名字是 + name +< / div>< / body>< / html>;
htmlDocumentToPrint.print（）;
我真的不在乎添加颜色 - 只是想格式化文档，用数据填充它，并将其打印出来。这是可能吗？
Print（）是一个窗口对象的方法。如果您使用javascript在窗口中创建文档，请在该窗口对象上调用print，它应该可以工作。
< script类型= 文本/ JavaScript的 >
var myWindow = window.open（''，''，'width = 200，height = 100'）
myWindow.document.write（this is'myWindow'）
myWindow 。打印（）;
< / script>
从 w3schools.com 窗口打开示例。
I know you can use window.print() to print the current page... but what I want to know is can I build a document using javascript in order to populate it with data and print it off?
Just like you can have html/xml as a javascript object, can you do something similar to this:
var name = "Matt";
var htmlDocumentToPrint = "<html><body><div style='width:300px; height:20px; background-color:#000; text-align:center;'>My name is " + name + "</div></body></html>";
htmlDocumentToPrint.print();
I don't really care about adding colors all that much-- just want to format a document, populate it with data, and print it off. Is this possible?
Print() is a method on the window object. If you create a document in a window using javascript, then call print on that window object, it should work.
<script type="text/javascript">
var myWindow = window.open('','','width=200,height=100')
myWindow.document.write("This is 'myWindow'")
myWindow.print();
</script>
Example modified from w3schools.com window open example.
