如何使用JavaScript获取HTML文档“所需”的最小宽度？

Question

I am using "wkhtmltoimage" to render images of HTML pages. Due to bugs in "wkhtmltoimage" (where it sometimes sets the page width to 32768 pixels), I need to be able to accurately establish how much the ideal page width should be.

Things like headers can stretch to fill available width, so straightforward document body width values are not helpful.

Is there any means with JavaScript (or jQuery) to determine what the best width should be?

Answer 1

使用screen.availWidth和screen.availHeight
