JS 中，一些東西不可用的三種展現(xiàn)方式。
我們?cè)赪EB項(xiàng)目中，有時(shí)候需要在用戶點(diǎn)擊某個(gè)東西的時(shí)候，一些東西不可用。如果在客戶端實(shí)現(xiàn)。最簡(jiǎn)單的就是利用disabled 。下面羅列的其中三種方式：依次是：不可用（disabled）；用一個(gè)空白來(lái)代替這個(gè)地方（Blank）；這個(gè)區(qū)域?yàn)榭?None)。具體可以查看這個(gè)Blog的源文件：
obj.disabled = false;

obj.style.visibility = "hidden";

obj.style.display = "none";

<SCRIPT language=javascript>
function ShowDisableObject(obj)
{
if(obj.disabled == false)
{
obj.disabled = true;
}
else{
obj.disabled = false;
}
var coll = obj.all.tags("INPUT");
if (coll!=null)
{
for (var i=0; i<coll.length; i++)
{
coll[i].disabled = obj.disabled;
}
}
}

function ShowBlankObject(obj)
{

{
obj.style.visibility = "visible";
}
else
{
obj.style.visibility = "hidden";
}

On this page I explain a simple DHTML example script that features invisibility, moving and the changing of text colour.

Example
Test TextMake test text invisible.
Make test text visible.
Move test text 50 pixels down.
Move test text 50 pixels up.
Change colour to red.
Change colour to blue.
Change colour to black.
Change the font style to italic.
Change the font style to normal.
Change the font family to 'Times'.
Change the font family to 'Arial'.

The script
The scripts work on this HTML element:

<DIV ID="text">Test Text</DIV>

#text {position: absolute;
top: 400px;
left: 400px;
font: 18px arial;
font-weight: 700;
}

These scripts are necessary for the three effects:

var DHTML = (document.getElementById || document.all || document.layers);

function getObj(name)
{
if (document.getElementById)
{
this.obj = document.getElementById(name);
this.style = document.getElementById(name).style;
}
else if (document.all)
{
this.obj = document.all[name];
this.style = document.all[name].style;
}
else if (document.layers)
{
this.obj = document.layers[name];
this.style = document.layers[name];
}
}

function invi(flag)
{
if (!DHTML) return;
var x = new getObj('text');
x.style.visibility = (flag) ? 'hidden' : 'visible'
}

var texttop = 400;

function move(amount)
{
if (!DHTML) return;
var x = new getObj('text');
texttop += amount;
x.style.top = texttop;
}

function changeCol(col)
{
