[英]Remove invalid html tags from a string
Is there any way with javascript to remove invalid HTML tags from a string? javascript有什么方法可以从字符串中删除无效的HTML标签?
Ex: <div> <foo></foo> </div>
should be transformed to <div></div>
例如:
<div> <foo></foo> </div>
应该转换为<div></div>
It looks like you're trying to roll your own form of HTML sanitizer. 看来您正在尝试使用自己的HTML清理程序形式。 I would not recommend that.
我不建议这样做。 Instead, check out other questions that have already asked for a sanitizer: Sanitize/Rewrite HTML on the Client Side
相反,请检查其他已经要求使用消毒剂的问题: 在客户机上消毒/重写HTML
Specifically, there's one available for use here: https://code.google.com/p/google-caja/wiki/JsHtmlSanitizer 具体来说,可在此处使用一种: https : //code.google.com/p/google-caja/wiki/JsHtmlSanitizer
Try this: 尝试这个:
<!DOCTYPE html>
<html>
<body>
<p id="demo"><foo></foo></p>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction()
{
var str=document.getElementById("demo").innerHTML,
reg = /<foo>|<\/foo>/i;
str = str.replace(reg, " ");
document.getElementById("demo").innerHTML=str;
}
</script>
</body>
</html>
