所以,这是我的代码(不是全部代码,只是你需要理解的代码):

<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js">
jQuery(document).ready(function(){
jQuery("nav ul ul").each(function(){
var navWidth=jQuery(this).width();
var liWidth=jQuery(this).closest("li").width();
var gaps=navWidth-liWidth;
var moveLeft=-gaps/2;
jQuery(this).css({"margin-left":moveLeft});
})
})
</script>
</head>

我不知道为什么,但jQuery仅在Dreamweaver中工作...为了在Dreamweaver中工作,我必须下载jQuery并将其添加到contains文件夹中,但对于一些pourposes,我粘贴了一个CDN。 如果我将所有内容上传到jsfiddle并将javascript代码放入javascript框中,它可以正常工作,但是从Dreamweaver中它并没有。

试试这个
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js" />
<script>
jQuery(document).ready(function(){
jQuery("nav ul ul").each(function(){
var navWidth=jQuery(this).width();
var liWidth=jQuery(this).closest("li").width();
var gaps=navWidth-liWidth;
var moveLeft=-gaps/2;
jQuery(this).css({"margin-left":moveLeft});
});
});

创建一个新文档并将以下内容粘贴到其中:
$(document).ready(function () {
$("nav ul ul").each(function () {
var navWidth = $(this).width();
var liWidth = $(this).closest("li").width();
var gaps = navWidth - liWidth;
var moveLeft = -gaps / 2;
$(this).css({
"margin-left": moveLeft
});
});
});
接下来,将其保存为包含文件夹中的global.js,然后将以下内容添加到头部:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script type="text/javascript" src="contain/global.js"></script>
这应该可以解决问题。 希望这会有所帮助。
