Retrieves whether client-side cookies are enabled in the browser.

Syntax

Scripting [ bEnabled = ] clientCaps.cookieEnabled

Possible Values

The property is read-only. The property has no default value.

Example

This example displays all the properties available through the clientCaps behavior.

<HTML xmlns:IE>
<HEAD>
<STYLE>
@media all {
IE\:CLIENTCAPS {behavior:url(#default#clientCaps)}
}
</STYLE>

<SCRIPT>
function window.onload()
{
sTempStr = "availHeight = " + oClientCaps.availHeight + "\n" +
"availWidth = " + oClientCaps.availWidth + "\n" +
"bufferDepth = " + oClientCaps.bufferDepth + "\n" +
"colorDepth = " + oClientCaps.colorDepth + "\n" +
"connectionType = " + oClientCaps.connectionType + "\n" +
"cookieEnabled = " + oClientCaps.cookieEnabled + "\n" +
"cpuClass = " + oClientCaps.cpuClass + "\n" +
"height = " + oClientCaps.height + "\n" +
"javaEnabled = " + oClientCaps.javaEnabled + "\n" +
"platform = " + oClientCaps.platform + "\n" +
"systemLanguage = " + oClientCaps.systemLanguage + "\n" +
"userLanguage = " + oClientCaps.userLanguage + "\n" +
"width = " + oClientCaps.width + "\n" ;

oPre.innerText = sTempStr;
}
</SCRIPT>

</HEAD>
<BODY>
<H1>clientCaps Behavior Sample</H1>

<P>This example shows how to use the new <B>clientCaps</B>
behavior, introduced in Microsoft Internet Explorer 5, to obtain
client capabilities information. The following is a sampling of the
information that can be obtained:</P>

<IE:CLIENTCAPS ID="oClientCaps" />

<PRE id="oPre"></PRE>
</BODY>
</HTML>
