使用纯JS删除所有内容 [英] Remove all content using pure JS
问题描述
我正在寻找一种方法来使用纯Javascript删除整个网页内容 - 没有库。
我试过了：
document.documentElement.innerHTML =whatever;
但不起作用：它取代了< html /> 元素。我正在考虑替换整个文档，包括可能的 doctype 和<？xml 声明。 p>
我认为浏览器正确地假定页面的内容类型为 text / html 将永远是一个网页 - 所以虽然你可以做一些像... ...
document.body.innerHTML ='' ;
它仍然会有一些HTML挂起。
您可以尝试...
document.documentElement.innerHTML ='';
...给我留下了< html>< / html> ; 。
window.location ='about：blank';
这将带您到一个空白页面 - 我相信大多数浏览器提供的内部机制。 p>
我认为最好的解决方案是使用 document.open（）来清除屏幕。
I'm looking for a way to remove the entire content of a web page using pure Javascript -- no libraries.
I tried:
document.documentElement.innerHTML = "whatever";
but that doesn't work: it replaces the inside of the <html/> element. I'm looking at replacing the entire document, including if possible the doctype and <?xml declaration.
I think a browser rightfully assumes a page with content-type text/html will always be a web page - so whilst you may do something like...
document.body.innerHTML = '';
It will still have some HTML hanging around.
You could try...
document.documentElement.innerHTML = '';
...which left me with <html></html>.
Yi Jiang did suggest something clever.
window.location = 'about:blank';
This will take you to a blank page - an internal mechanism provided by most browsers I believe.
I think however the best solution is to use document.open() which will clear the screen.
