如何解决如何使内容从中间/顶部开始而不是从底部开始？
| 我正在使用此javascript使图像从底部垂直滚动到顶部，但是我不知道如何在填充框架时使图像开始滚动。现在，当网站/脚本加载时，它为空，我想更改它。 谢谢！ （对于较长的代码，我感到抱歉） 这是代码：<script>
step = 1
nextMessage = 1
counter = 20;
function initTSV1() {
tsvDisplay = document.getElementById(\"tsvcont\")
for (var i = 0; i < 2; i++) {
newDiv = document.createElement(\"DIV\")
newDiv.setAttribute(\"id\",\"tsvdiv\" + i)
/*newDiv.onmouseover=function(){
clearTimeout(timer);
counter = 40;
}
newDiv.onmouseout=function(){
counter = 20;
scrollTSV1();
}*/
newDiv.style.position = \"absolute\"
newDiv.style.padding = \"0 5 0 10\" // top right bottom left
tsvDisplay.appendChild(newDiv)
}
tsvDv0 = document.getElementById(\"tsvdiv0\")
tsvDv1 = document.getElementById(\"tsvdiv1\")
tsvDv0.innerHTML = info[0]
tsvDv1.innerHTML = info[1]
tsvDv0.style.top = tsvDisplay.offsetHeight
tsvDv1.style.top = tsvDisplay.offsetHeight + tsvDv0.offsetHeight + \"px\"
scrollTSV1()
}
function scrollTSV1() {
/*$(\"#tsvcont\").mouseover(function() {
counter = 40;
}).mouseout(function() {
counter = 20;
});*/
$(\"#tsvcont\").mouseout(function() {
counter = 20;
}).mouseover(function() {
counter = 40;
});
tsvDv0Pos = parseInt(tsvDv0.style.top)
tsvDv1Pos = parseInt(tsvDv1.style.top)
tsvDv0Pos -= step
tsvDv1Pos -= step
tsvDv0.style.top = tsvDv0Pos + \"px\"
tsvDv1.style.top = tsvDv1Pos + \"px\"
if (tsvDv0Pos < -tsvDv0.offsetHeight) {
nextMessage++
if (nextMessage == info.length) {
nextMessage = 0
}
tsvDv0.innerHTML = info[nextMessage]
if (tsvDv1.offsetHeight < tsvDisplay.offsetHeight) {
if (tsvDv1.offsetTop < tsvDisplay.offsetHeight - tsvDv1.offsetHeight) {
tsvDv0.style.top = tsvDisplay.offsetHeight + \"px\"
}
else {
tsvDv0.style.top = tsvDv1.offsetTop + tsvDv1.offsetHeight + \"px\"
}
}
else {
tsvDv0.style.top = tsvDv1.offsetTop + tsvDv1.offsetHeight + \"px\"
}
}
if (tsvDv1Pos < -tsvDv1.offsetHeight) {
nextMessage++
if (nextMessage == info.length) {
nextMessage = 0
}
tsvDv1.innerHTML = info[nextMessage]
if (tsvDv0.offsetHeight < tsvDisplay.offsetHeight) {
if (tsvDv0.offsetTop < tsvDisplay.offsetHeight - tsvDv0.offsetHeight) {
tsvDv1.style.top = tsvDisplay.offsetHeight + \"px\"
}
else {
tsvDv1.style.top = tsvDv0.offsetTop + tsvDv0.offsetHeight + \"px\"
}
}
else {
tsvDv1.style.top = tsvDv0.offsetTop + tsvDv0.offsetHeight + \"px\"
}
}
timer = setTimeout(\"scrollTSV1()\",counter);
}
// add onload=\"initTSV1()\" to the opening BODY tag
</script>
<style>
#tsvcont{
position:relative;
width:290px; /* width = target width - (border * 2) */
height:500px;
overflow:hidden;
text-align:left;
}
#tsvdiv0 {
position:absolute;
width:290px; /* width = tsvcont width - ((border + padding) * 2) */
padding:0px 0px 30px 0px;
height:600px;
}
#tsvdiv1{
position:relative;
width:290px; /* width = tsvcont width - ((border + padding) * 2) */
padding:30px 5 0px 5;
height:600px;
}
</style>
</HEAD>
<BODY onLoad=\"initTSV1()\">
<DIV id=\"tsvcont\" style=\"position:relative; width:290px; height:500px; overflow:hidden; text-align:left; left: 50px\";></DIV>
解决方法
而不是将函数放在正文中，因为您使用的是jQuery
尝试这个：
$(function(){
initTSV1();
});
