Example
Use The Evaluator to experiment with the setEndPoint() method. Begin by creating
two independent text ranges, one for the myP element and one for myEM:
a = document.body.createTextRange()
a.moveToElementText(myP)
b = document.body.createTextRange()
b.moveToElementText(myEM)
Before moving any end points, compare the HTML for each of those ranges:
a.htmlText
b.htmlText
Now, move the start point of the a text range to the end point of the b text range:
a.setEndPoint(“StartToEnd”, b)
If you now view the HTML for the a range,
a.htmlText
TextRange.setEndPoint()
you see that the tag of the original a text range is nowhere to be found. This
demonstration is a good lesson to use the setEndPoint() method primarily if you
are concerned only with visible body text being inside ranges, rather than an element
with its tags.
