好吧,我做了一些修改,解决了一些问题,但现在它没有通过所有字母,一些字母可见,然后脚本停止。另外,我怎么让这些字母淡入?我以为我有这个,但剧本不会因为某种原因暂停,你看不到褪色。

window.onload = function DOL() {
DoOnLoad()
}
function DoOnLoad() {
//alert("DoOnLoad");
/* Change the opacity of every letter randomly,
CAN CHANGE IN SMALL TAG */
if ($SwappedLets <= $TotalLetters + 1) {
$RanNum = Math.floor(Math.random()*17);
//alert(window["$L" + $RanNum]);
if (window["$L" + $RanNum] == false) {
window["$L" + $RanNum] = true;
OPIncre($RanNum);
}
}
}
function OPIncre(RN) {
if (document.getElementById("tL" + RN).style.opacity <= 1) {
document.getElementById("tL" + RN).style.opacity = $Holderval + 0.001;
$Holderval = $Holderval + 0.001;
window.setTimeout(OPIncre(RN),600);
}
else {
$SwappedLets = $SwappedLets + 1;
$Holderval = 0;
window.setTimeout(DoOnLoad,500);
}
}

---- OLD:
我是Javascript的新手,我无法让脚本随机更改html元素的不透明度。默认情况下,元素的不透明度在css中设置为0。我试过环顾四周,还没有找到解决方案。我在Firefox的Javascript错误控制台中没有收到任何错误。有什么明显错误的吗?

答案 0 :(得分:0)
不确定“tL”是什么类型的元素,但假设它们属于<p>
类型,以下脚本应该可以解决这个问题:
var $elements;
window.onload = function DOL() {
// Get all elements
$elements = $("p[id^='tL']");
// Loop through all of them
$elements.each(function(i, e) {
e.style.opacity = Math.random() + 0.17;
});
}
请注意,我在这里使用jQuery。由于您对变量使用了dollor符号,我假设您也在使用它。
