1. 登入部落格 → 修改 HTML
2. Ctrl+F 寻找代码 </style>
3. 在 </style> 下面添加以下代码：
<script language="javascript" type="text/javascript">
/* toggle() checks to see if the images has already been faded
or not and sends the appropriate variables to opacity(); */
function toggle(el,milli) {
// Get the opacity style parameter from the image
var currOpacity = document.getElementById(el).style.opacity;
if(currOpacity != 0) { // if not faded
fade(el, milli, 100, 0);
} else { // else the images is already faded
fade(el, milli, 0, 100);
}
}
/* changeOpacity() uses three different opacity settings to
achieve a cross-browser opacity changing function. This
function can also be used to directly change the opacity
of an element. */
function changeOpacity(el,opacity) {
var image = document.getElementById(el);
// For Mozilla
image.style.MozOpacity = (opacity / 100);
// For IE
image.style.filter = "alpha(opacity=" + opacity + ")";
// For others
image.style.opacity = (opacity / 100);
}
/* fade() will fade the image in or out based on the starting
and ending opacity settings. The speed of the fade is
determined by the variable milli (total time of the fade
in milliseconds)*/
function fade(el,milli,start,end) {
var fadeTime = Math.round(milli/100);
var i = 0; // Fade Timer
// Fade in
if(start < end) {
for(j = start; j <= end; j++) {
// define the expression to be called in setTimeout()
var expr = "changeOpacity('" + el + "'," + j + ")";
var timeout = i * fadeTime;
// setTimeout will call 'expr' after 'timeout' milliseconds
setTimeout(expr,timeout);
i++;
}
}
// Fade out
else if(start > end) {
for(j = start; j >= end; j--) {
var expr = "changeOpacity('" + el + "'," + j + ")";
var timeout = i * fadeTime;
setTimeout(expr,timeout);
i++;
}
}
}
</script>
4. 然后，在 <head> 上面添加以下代码：
<div class="enter" onClick="javascript:toggle('wise', 3000); this.style.display='none';
document.getElementById('june').style.display=''">
<img src="http://img.juhife542d.com图片网址"
style="opacity:0.4;filter:alpha(opacity=40)"
onmouseover="this.style.opacity=1;this.filters.alpha.opacity=100"
onmouseout="this.style.opacity=0.7;this.filters.alpha.opacity=40"/>
</div>
<div id="wise" style="filter : alpha(opacity=0); -moz-opacity : 0; opacity : 0;">
<div id="june" style="display : none;">
5. Ctrl+F 寻找代码 <style type="text/css">，然后在下面添加以下代码：
6. 预览看看你的 Click 图片有没有出现，即可保存。

表示要大大大大大的撒花一下，这个充满考试的一个课程，终于xx的结束了 
而且一年半的时间，堆了许多废纸习题资料笔记那些，一叠一叠的纸张，丢掉的话，我复印那些纸也是一笔钱；带回家我嫌很麻烦，我真的不知道要怎么处置啊啊啊啊啊啊啊w(ﾟДﾟ)w 请理解一个住在二楼还要是距离宿舍门口最远的房间的我。到最后wo决定把资料笔记带回家收旧报纸去，至于历年考题
对于这个课程，我、没、有、丝、毫、的、留、念。
毕竟我是过来人嘛 :P
