因此,这是我的代码(不是全部,只是您需要了解的内容):

HTML:

<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,但是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,但是出于某些目的,我粘贴了CDN。
如果我将所有内容都上传到jsfiddle并将javascript代码放入javascript框中,则可以使用,但是从Dreamweaver中则无效。

最佳答案

尝试这个

<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});
            });
        });

关于javascript - jQuery可在Dreamweaver中使用,但不能在浏览器中使用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/28652595/
