Sets or retrieves the string identifying the object.
Syntax
| HTML | <element id="p" ... > |
|---|---|
| JavaScript | |
Property values
Type: String
any alphanumeric string that begins with a letter. The underscore (_) can also be used.
Remarks
The id should be unique throughout the scope of the current document. If a document contains more than one object with the same identifier, the objects are exposed as a collection that can be referenced only in ordinal position.
Examples
This example gets the id attribute of each cell of a table. When the user clicks a cell, the object of the cell is passed to a function which returns the object's ID.
<script type="text/javascript">
function getID(oObject)
{
var id = oObject.id;
console.log("This object's ID attribute is set to \"" + id + "\".");
}
</script>
<table border="">
<tr>
<td id="firstCell" onclick="getID(this);">Table Cell 1</td>
<td id="secondCell" onclick="getID(this);">Table Cell 2</td>
<td id="thirdCell" onclick="getID(this);">Table Cell 3</td>
</tr>
</table>
