Internet Explorer 6, Part I: DOM Standards Support

Replacing DOM Strings

Internet Explorer 6 is richer in functionality than Internet Explorer 5.5, as far as text manipulation is concerned. The replaceData() method is one example. Operating on text nodes, it replaces a substring in the text node data. You can specify the offset of the substring and its length, as well as the new string to insert. Here is its syntax:

textObj.replaceData(offset, count, data);

where:

Let's create a text node at the document level. We put the following line in the header of this page:

txtObj = document.createTextNode
  ("Doc JavaScript BiWeekly Columns");

and then let's replace a substring that starts at offset 15 and of length 16, with "Daily Tips". Click this button to make it happen in both Netscape 6 and Internet Explorer 6 ("Doc JavaScript Daily Tips"). Click in Internet Explorer 5.x and get an error message:

Here is the definition of this button:

<FORM>
<INPUT TYPE="button" VALUE="Replace a Substring"
  onClick="javascript:handleClick()">
</FORM>

And here is the definition of the event handler above:

function handleClick() {
  txtObj.replaceData(15, 16, "Daily Tips");
  alert(txtObj.data);
}
