当谈到 javascript 时,我仍然是一个新手,但我无法为 div 设置动画,当用户将光标移到图像上时,我想从底部向上滑动图像。我已经成功使用几乎相同的代码将 div 淡入和淡出视图,但由于某种原因,它不想在这种情况下工作。这是它的 html/php 方面:
echo '
<div class="still" style="clear:left">
<div class="thumbnail" onmouseover="show_title('.$work['position'].');" onmouseout="hide_title('.$work['position'].');">
<div class="still_title" id="still_title'.$work['position'].'">
<br>'.$work['title'].'
</div>
<a href="'.$work['vimeo'].'" rel="shadowbox"><img src="'.$work['thumbnail'].'" class="still_img"></a>
</div>
<div class="description"><p>'.$work['description'].'</p>
</div>
</div>
';
这是我在正常运行时遇到问题的javascript..
var i = 0;
function show_title(position) {
var titledelay = setInterval(show_title_animation(position),30);}
function show_title_animation(position) {
still_id = "still_title" + position;
title_position = document.getElementById(still_id);
while (i<100) {
i++;
title_position.style.height = i + "px";
}
if (i==100) {
alert(title_position);
clearInterval(titledelay);
}
}
编辑:它现在可以工作,但在完成循环后它不会重置..
var i = 0;
function show_title(position) {
var titledelay = setInterval(function(){ show_title_animation(position); }, 10);
}
function show_title_animation(position) {
still_id = "still_title" + position;
title_position = document.getElementById(still_id);
while (i<50) {
i++;
title_position.style.height = i + "px";
break;
}
if (i==50) {
clearInterval(titledelay);
i=0;
}
}
