当我们在textarea中粘贴代码时，是否有像ckeditor这样的脚本删除样式和脚本？ [关闭]

Question

Is there any script like ckeditor that removes css and script when we paste code in a textarea? I want to remove css and script when user copy text from some where else and pastes it in my website

Answer 1

$myHtml = // here is your html;
$doc = new DOMDocument();
$doc->loadHTML($myHtml);

removeElementsByTagName('script', $doc);
removeElementsByTagName('style', $doc);

$html = $doc->saveHtml();

function removeElementsByTagName($tagName, $document) {
  $nodeList = $document->getElementsByTagName($tagName);
  for ($nodeIdx = $nodeList->length; --$nodeIdx >= 0; ) {
    $node = $nodeList->item($nodeIdx);
    $node->parentNode->removeChild($node);
  }
}
