使用JavaScript清除HTML页面 [英] Clear HTML page using JavaScript
问题描述
有没有办法删除带有JavaScript功能的页面上现有内容的部分内容?
喜欢这样:
Is there any way to delete portions of existing content on a page with a JavaScript function?
Like this:
<I WANT THIS CLEARED>
<IS THERE ANY JAVASCRIPT OR HTML STATEMENT I CAN PUT HERE?>
<I WANT THIS DISPLAYED>
我应该把什么放在<是否有任何JAVASCRIPT或HTML声明我可以放在这里吗?>
?
我知道在零件之后加上< div style =display:none>< plaintext>
我想显示将隐藏页面的结尾,但如何清除开头?
I know putting <div style="display:none"><plaintext>
after the part I want displayed will hide the end of a page, but how do I clear the beginning?
推荐答案
您可以使用 document.body.innerHTML =
。只要浏览器处理页面,它就会取出正文中的所有内容。请参阅以下示例:
You can use document.body.innerHTML = ""
. It will take out everything in the body so far as the browser processes the page. See the following example:
<html>
<head></head>
<body>
<p>This should not appear</p>
<script type="text/javascript">
document.body.innerHTML = '';
</script>
<p>This should appear.</p>
</body>
</html>
然而,这并不是实现这一目标的好方法。如果你想隐藏一些文本,可以考虑其他人提到的jQuery。
This is, however, not a great way to accomplish this. If you want some text hidden, consider jQuery as others have mentioned.
