insertData (W3C DOM Core method)

Example

var sentence = document.createTextNode
  ("When you're smiling, the whole world smiles with you.");

sentence.insertData(21, "yes when you're smiling, ");

In the example above we create a Text node with the value When you're smiling, the whole world smiles with you., then we use the insertData method to insert the string yes when you're smiling, at character offset 21.

The final result is a single Text node with the data (and nodeValue) When you're smiling, yes when you're smiling, the whole world smiles with you., that has a length of 78.
