我一直试图这样做无济于事:(从我研究的内容来看,有两种方法可以改变JavaScript中声明的类值:
的document.getElementById(ⅴ).setAttribute(属性,值);
或
document.getElementById(v).className = value;
但是,我试过了两个,他们正在做深蹲:(我昨天浪费了一整天才弄清楚这一点无济于事:(
这是我的代码:

我知道有很多粗糙的边缘代码,但是我很紧张,而且我还没精通JavaScript语法。
以下是我的代码的具体内容以及我要完成的内容:
我为网站使用全局css代码,因此我的大多数声明都存储在那里。我现在已经在内部制作了javascript代码(可以这么说)。但是,如果这样可行,我计划将其添加到我的站点的全局JavaScript存储库( styles.js 一个)。我添加了jQuery,以便稍后使用它(我还没有,因为我现在只是想学习它)。
好的,现在从你看到的,这段代码只是一个标签界面。这是我的标签的CSS代码:
/* CSS Tabs */
#navlist {
padding: 3px 0;
margin-left: 0;
border-bottom: 1px solid #778;
font: bold 12px Verdana, sans-serif;
}
#navlist li {
list-style: none;
margin: 0;
display: inline;
}
#navlist li a.active {
padding: 3px 0.5em;
margin-left: 3px;
border: 1px solid #778;
border-bottom: none;
background: #DDE;
text-decoration: none;
}
#navlist li a:link { color: #448; }
#navlist li a:visited { color: #448; }
#navlist li a.active:hover {
color: #000;
background: #AAE;
border-color: #227;
}
#navlist li a.current {
padding: 3px 0.5em;
margin-left: 3px;
border: 1px solid #778;
border-bottom: 1px solid white;
text-decoration: none;
background: white;
cursor: text;
}
#navlist li a.current:hover {
background: white;
border-bottom: 1px solid white;
cursor: text;
color: #448;
}
#navlist div #content {
font-size: 1em;
}
选项卡应该在点击时更改iframe的内容。有问题的JavaScript代码的工作就是简单地改变点击标签的外观。在上面的CSS代码中,这是名为“current”的类,而默认样式是“active”类。
应该处理更改的代码是changeTab(tab)。首先,我将所有选项卡设置为默认类“active”。当我单击选项卡时,changeTab应该启动(也是onLoad,但我没有先添加)。这就是我遇到问题的地方。目标选项卡上的类值没有变化。
首先,我添加了一些catch代码,以查看onClick事件是否正常运行(我在changeTab函数中添加警报代码的原因)。然后,我添加了一个代码,让我可以看到类属性的最终值( test(tab)函数)。它应该显示标签的Id和它的类属性的值。
当我试用它时,我确实在changeTab中获取了传递的参数,它告诉我onClick正在运行。但是测试告诉我标签是未定义的。因此,无论我点击哪个标签,“当前”类都将应用于最后一个标签(“month1”)。
我的工作浏览器是IE8,由于这是一个公司内部网站点,因此我不需要它与其他浏览器兼容,因为我们公司希望我们将IE专门用于与工作相关的任务。
请帮助:(另外,如果您可以推荐我正在做的替代品,请随时给他们:)
非常感谢,

我已经忘记了使用jQuery已经很久了,但是在setAttribute之前尝试调用removeAttribute。
