Instance Methods

splitText(offset : Number) : Text

Splits this into 2 Text nodes at the specified offset into data. The first portion of data stays in this and the remainder is placed in a new Text that is returned by the call to splitText(). The remainder Text is inserted after this in this.parentNode.

Example:

<div id='foo'>Initial Text.</div>
<script>
  var foo = document.getElementById('foo');
  var initialText = foo.firstChild;

  console.log('length before split: ' + foo.childNodes.length);

  for (var i = 0; i < foo.childNodes.length; i++) {
    console.log('  ' + i +': "' + foo.childNodes[i].data + '"');
  }
  console.log();

  var remainder = initialText.splitText(3);
  console.log('initialText after split: "' + initialText.data + '"');
  console.log('remainder after split: "' + remainder.data + '"');
  console.log();

  console.log('length after split: ' + foo.childNodes.length);

  for (var i = 0; i < foo.childNodes.length; i++) {
    console.log('  ' + i +': "' + foo.childNodes[i].data + '"');
  }
