Examples

View live exampleThis example uses the onfocus event to make INPUT_text and label objects more accessible. When the INPUT_text object has focus, the onfocus event fires and the backgroundColor, fontSize, and fontWeight properties are changed to give the control more prominence.

...
<style type="text/css">
.normal {
	background-color: white;
	color: black;
	font-weight: normal;
	font-size: 8pt;
	font-family: Arial;
}
.accessible {
	background-color: silver;
	font-weight: bold;
	font-size: 10pt;
}
</style>
<script type="text/javascript">
function fnSetStyle(){
   event.srcElement.className="accessible";
   var oWorkLabel=eval(event.srcElement.id + "_label");
   oWorkLabel.className="accessible";
}
</script>
<label for="oInput" class="normal" id="oInput_label">Enter some text</label>
<input type="text" class="normal" onfocus="fnSetStyle()" id="oInput">

Notes

Remarks

Note Using the setActive method has no effect on document focus. Using the focus method on an individual element causes the element to gain focus and become the active element. When one object loses activation and another object becomes the activeElement, the onfocus event fires on the object becoming the activeElement only after the onblur event fires on the object losing activation. Use the focus events to determine when to prepare an object to receive input from the user. Elements cannot receive focus until the document is finished loading. For Microsoft Internet Explorer 5.5 and later, focus on a document, and the active element of a document can be managed separately. The synchronous events onactivate and ondeactivate provide better control for managing activation changes. As of Microsoft Internet Explorer 5, elebrowserments retain focus within the current history when the user returns to a page. To avoid firing the onfocus event unintentionally for an element when the document loads, invoke the focus method on another element. As of Internet Explorer 5, you can force elements that do not implicitly receive focus to receive focus by adding them to the document tabbing order using the TABINDEX attribute. Sets focus to an object. To invoke this event, do one of the following:

Click an object.
Use keyboard navigation.
Invoke the focus method.
Invoke the setActive method.
