Scripting	object.disabled [ = bDisabled ]

DHTML可能的值

bDisabled

Boolean that specifies or receives one of the following values. false Default. Element is not disabled. true Element is disabled.

The property is read/write. The property has a default value of false.

Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see about dynamic properties.

remarks

when an element is disabled, it appears dimmed and does not respond to user input. disabled elements do not respond to mouse events, nor will they respond to the contenteditable property.

if an element's disabled property is set to false but it is contained within a disabled element, it cannot override the disabled state of its container.

DHTML代码范例

This example uses the disabled property to enable or disable a style object and a control.

<style id="ostyle">
.styletest{background-color: black; color: white;}
.styletest2{background-color: black; color: red;}
</STYLE>
<SCRIPT>
function fnSwitch(){
if(oParagraph.enablement == "enabled"){
// Use an arbitrary attribute to track the status.
oParagraph.enablement = "disabled";
oButton.value = "Set disabled to false";
oStyle.disabled = true;
oDisableMe.disabled = true;
}
else{
oButton.value = "Set disabled to true";
oParagraph.enablement = "enabled";
oStyle.disabled = false;
oDisableMe.disabled = false;
}
}
</SCRIPT>
...
<P enablement="enabled" ID="oParagraph" CLASS="styletest">
A paragraph of text.
<INPUT TYPE="button" ID="oDisableMe" CLASS="styletest"
VALUE="Demonstration Button" onclick="alert('Demonstration button')">
</P>
<INPUT TYPE="button" ID="oButton" VALUE="Set disabled to true"
onclick="fnSwitch()">
