Examples
This example uses the getBoundingClientRect method to retrieve the coordinates of the bounds of the text rectangles within the element.
<SCRIPT>
function getCoords(oObject) {
oBndRct=oObject.getBoundingClientRect();
alert("Bounding rectangle = \nUpper left coordinates: "
+ oBndRct.left + " " + oBndRct.top +
"\nLower right coordinates: "
+ oBndRct.right + " " + oBndRct.bottom);
}
</SCRIPT>
</HEAD>
<BODY>
<P ID=oPara onclick="getCoords(this)">
Notes
Use this syntax to access the top coordinate of the second text rectangle of a TextRange object:
oRct = oTextRange.getClientRects();
oRct[1].top;
Note that the collection index starts at 0, so the second item index is 1. To access the top coordinate of the bounding rectangle of an object, use this syntax:
oBndRct = oElement.getBoundingClientRect();
oBndRct.top;
