<p class="p2" style="line-height:17pt"> 本節(jié)將向您介紹一個(gè)動(dòng)態(tài)濾鏡顯示的例子中,在這個(gè)例子中您可以隨意改變透明度的開始值、結(jié)束值和樣式(style)。

<p class="p2" style="line-height:17pt"> 這個(gè)例子先是在<head>中加入了一段JavaScript語(yǔ)句,代碼如下:</p>
<p class="p2" style="line-height:17pt"> <script language="javascript">
<br>
<!-- <br>
function setfilter(){<br>
myimage.filters.alpha.opacity=document.forms(0).opacity.value<br>
myimage.filters.alpha.finishopacity=<br>
document.forms(0).finishopacity.value<br>
myimage.filters.alpha.style=document.forms(0).setstyle.value } <br>
--> <br>
</script></p>
<p class="p2" style="line-height:17pt"> 這段代碼定義圖片的透明度等于表單中輸入的對(duì)應(yīng)的透明度的值。myimage是一個(gè)類<br>
,標(biāo)識(shí)圖片。它的CSS樣式是這樣定義的:</p>
<p class="p2" style="line-height:17pt"> <img id="myimage"
src="ss07075.jpg"<br>
style="filter:alpha();position:absolute;top:10;left:0;"></p>
<p class="p2" style="line-height:17pt"> 最后,在圖片下方加入三個(gè)表單,分別對(duì)應(yīng)輸入初始透明度、結(jié)束透明度和樣式值<br>
,通過(guò)透明度的改變,使隱藏在圖片下的文字顯示出來(lái)。</p>
<p class="p2" style="line-height:17pt"> 下一節(jié)將向您介紹一種特殊的濾鏡效果。</p>
