javascript导航问题消失了

Question

我正在为一位朋友(他在一家律师事务所工作)进行一些网站更改,他的网站左侧有一个导航栏.在悬停时,这些显示子菜单.不幸的是,他试图取出其中一个子菜单项并丢失了子菜单导航的所有功能.现在,它不显示子菜单,而只显示错误.

这是以前的代码(它的工作原理):

<script language="JavaScript">
<!--
function mmLoadMenus() {
    if (window.mm_menu_0327091831_0) return;

    window.mm_menu_0327091831_0 = new Menu("root",225,30,"Optima, Verdana, Helvetica Neue, sans-serif",14,"#FFFFFF","#FFFFFF","#7E7D7D","#B3B3B3","left","middle",8,0,250,-5,7,true,false,true,0,true,true);

    mm_menu_0327091831_0.addMenuItem("HARRY&nbsp;GRIFF,&nbsp;P.C.","location='harry-griff.html'");
    mm_menu_0327091831_0.addMenuItem("DOUGLAS&nbsp;E.&nbsp;LARSON,&nbsp;P.C.","location='doug-larson.html'");
    mm_menu_0327091831_0.addMenuItem("STEPHEN&nbsp;L.&nbsp;LAICHE,&nbsp;P.C.","location='stephen-laiche.html'");
    mm_menu_0327091831_0.addMenuItem("BRAD&nbsp;R.&nbsp;WRIGHT,&nbsp;P.L.L.C.","location='brad-wright.html'");
    mm_menu_0327091831_0.hideOnMouseOut=true;
    mm_menu_0327091831_0.bgColor='#555555';
    mm_menu_0327091831_0.menuBorder=1;
    mm_menu_0327091831_0.menuLiteBgColor='#FFFFFF';
    mm_menu_0327091831_0.menuBorderBgColor='#777777';

    mm_menu_0327091831_0.writeMenus();
} // mmLoadMenus()
//-->?????
</script>

这是以下代码:

<script language="JavaScript">
<!--
function mmLoadMenus() {
    if (window.mm_menu_0327091831_0) return;

    window.mm_menu_0327091831_0 = new Menu("root",225,30,"Optima, Verdana, Helvetica Neue, sans-serif",14,"#FFFFFF","#FFFFFF","#7E7D7D","#B3B3B3","left","middle",8,0,250,-5,7,true,false,true,0,true,true);

    mm_menu_0327091831_0.addMenuItem("HARRY&nbsp;GRIFF,&nbsp;P.C.","location='harry-griff.html'");
    mm_menu_0327091831_0.addMenuItem("DOUGLAS&nbsp;E.&nbsp;LARSON,&nbsp;P.C.","location='doug-larson.html'");
    mm_menu_0327091831_0.addMenuItem("STEPHEN&nbsp;L.&nbsp;LAICHE,&nbsp;P.C.","location='stephen-laiche.html'");
    mm_menu_0327091831_0.addMenuItem("BRAD&nbsp;R.&nbsp;WRIGHT,&nbsp;P.L.L.C.","location='brad-wright.html'");
    mm_menu_0327091831_0.addMenuItem("BRAD&nbsp;R.&nbsp;WRIGHT,&nbsp;P.L.L.C.","location='rob-zentner.html'");
    mm_menu_0327091831_0.hideOnMouseOut=true;
    mm_menu_0327091831_0.bgColor='#555555';
    mm_menu_0327091831_0.menuBorder=1;
    mm_menu_0327091831_0.menuLiteBgColor='#FFFFFF';
    mm_menu_0327091831_0.menuBorderBgColor='#777777';

    mm_menu_0327091831_0.writeMenus();
} // mmLoadMenus()????
//-->
</script>

继承人正在运作的网站:

第一个站点(这是有效的,但是需要一些更新的页面

继承人网站不工作:

第二个网站(这不起作用,将鼠标悬停在律师资料按钮上)

我刚刚粘贴了更改过的javascript,因为我认为问题出在那里,但如果需要,我可以发布更多内容.

谢谢大家的帮助!

你有2个不同的版本mm_menu.js.其中一个有语法错误.注意StackOverflow的语法突出显示在下面的2个片段中.

看到问题了吗？在错误版本顶部的标题中,注释未正确关闭.多行Javascript评论以/*&结尾开头*/.但是,此标题注释已被破坏,它没有结束注释标记.因此整个文件被注释掉并且Menu不存在.

正确地关闭那个评论,我打赌事情会好起来的.

所以你知道如何成为一个更好的开发者,这就是我如何解决这个问题.

我只是在Chrome中打开了开发人员工具,并查看了JS控制台.在鲜红的地方,我看到了这个:

这立即告诉我语法错误,以及错误所在的文件和近似行.查看该文件,然后看到Chromes语法突出显示样式的整个文件,如注释(绿色),使得它很明显是什么.
