我有这个简单的 JavaScript 代码,应该将 div 放入和 div 输出。它在滑入时工作完美。通过完美工作可以轻松滑动 div。但是,当您单击滑出时,div 就会从浏览器中消失。我不知道为什么,我找不到错误。我的代码在这里
<!DOCTYPE html>
<html>
<head></head>
<body>
<script>
function slideIt()
{
var stopPosition = 50;
var slidingDiv = "";
slidingDiv = document.getElementById("d3");
if (parseInt(slidingDiv.style.left) < stopPosition )
{
slidingDiv.style.left = parseInt(slidingDiv.style.left) + 2 + "px";
setTimeout(slideIt, 1);
}
}
function slideOut()
{
var startPosition =-150;
var slidingDiv = "";
slidingDiv = document.getElementById("d4");
if (parseInt(slidingDiv.style.left) > startPosition )
{
slidingDiv.style.left = parseInt(slidingDiv.style.left) - 2 + "px";
setTimeout(slideOut(), 1);
}
}
</script>
<div id="d1" onclick="slideIt();">Slide in</div>
<div id="d2" onclick="slideOut();">Slide out</div>
<div id="d3" style="position: absolute; left:-150px; top:300px" >horizontally sliding div</div>
<div id="d4" style="position: absolute; left:150px; top:300px">horizontally sliding div</div>
</body>
