insertAdjacentHtml method

void insertAdjacentHtml (String where, String html, { NodeValidator validator, NodeTreeSanitizer treeSanitizer })

Parses text as an HTML fragment and inserts it into the DOM at the specified location.

The where parameter indicates where to insert the HTML fragment:

'beforeBegin': Immediately before this element.
'afterBegin': As the first child of this element.
'beforeEnd': As the last child of this element.
'afterEnd': Immediately after this element.

var html = '
content
'; // Inserts as the first child document.body.insertAdjacentHtml('afterBegin', html); var createdElement = document.body.children0; print(createdElement.classes0); // Prints 'something'

Implementation

void insertAdjacentHtml(String where, String html,
    {NodeValidator validator, NodeTreeSanitizer treeSanitizer}) {
  if (treeSanitizer is _TrustedHtmlTreeSanitizer) {
    _insertAdjacentHtml(where, html);
  } else {
    _insertAdjacentNode(
        where,
        createFragment(html,
            validator: validator, treeSanitizer: treeSanitizer));
  }
}
