insertAdjacentHtml method - SvgElement class - dart:svg library (original) (raw)

void insertAdjacentHtml(

1. String where,
2. String text, {
3. NodeValidator? validator,
4. NodeTreeSanitizer? treeSanitizer, })

override

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 = '<div class="something">content</div>';
    // Inserts as the first child
    document.body.insertAdjacentHtml('afterBegin', html);
    var createdElement = document.body.children[0];
    print(createdElement.classes[0]); // Prints 'something'
