我正在创建一个HTML程序,它有一个包含12个小div的主div,它们向左移动,当它们有换行符时,它们应该位于main的位置(0,0) DIV。我无法重新定位小div,它总是在线的末尾换行。
<!DOCTYPE>
<html>
<head>
<title></title>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<style type="text/css">
div.micapa {
/* Decoration */
background-color: red;
width:100px;
height:100px;
border: 4px ridge orange;
font-size: 26px;
text-align: center;
color: purple;
font-weight: bold;
line-height: 100px;
margin-left: 3px;
margin-right: 3px;
/* Location */
float: left;
display: inline;
}
div#container {
white-space: nowrap;
width: 100%;
height: 108px;
border: 5px ridge cyan;
}
</style>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
$(document).ready(function(){
$(".micapa").hover(function (){
boxList = document.querySelectorAll(".micapa");
marginIzqAux = $(this).css("margin-left");
marginIzqLimit = parseInt($("body").css("width"));
marginIzq = (((parseInt(marginIzqAux) + 100) % marginIzqLimit).toString()) + "px";
$(".micapa:first-child").animate({
marginLeft: marginIzq,
marginTop: "0px"
}, 2500, function() {
i = boxList.length - 1;
while(i >= 0) {
if (marginIzqLimit < parseInt($(boxList[i]).css("margin-left"))) {
$(boxList[i]).css("margin-top", "-100px");
i = -1;
} else
--i;
}
});
});
});
</script>
</head>
<body>
<div id="container">
<div class="micapa">1</div>
<div class="micapa">2</div>
<div class="micapa">3</div>
<div class="micapa">4</div>
<div class="micapa">5</div>
<div class="micapa">6</div>
<div class="micapa">7</div>
<div class="micapa">8</div>
<div class="micapa">9</div>
<div class="micapa">10</div>
<div class="micapa">11</div>
<div class="micapa">12</div>
</div>
</body>
</html>
我该如何继续?

答案 0 :(得分:1)
试试这个
$(".micapa:first")
而不是
$(".micapa:first-child")
答案 1 :(得分:1)
试试这个:
$(".micapa:first")
或者:
$(".micapa").first()
这是因为.micapa
实际上不是first-child
。
