jquery - 菜单悬停效果在 IE 中不起作用

Question

我正在从事使用悬停菜单的元素。这在 Chrome 和 FF 中运行良好。但现在在 IE7 和 IE8 中工作。此菜单动态绑定(bind)到表单。如下所示。

您看到的任何菜单效果都在 Chrome 中正常运行。但不是在 IE 中，如下所示。

我的 CSS 文件如下。

/* reset  list style */
.cbp-tm-menu,
.cbp-tm-menu ul {
    list-style: none;
}

/* set menu position; change here to set to relative or float, etc. */
.cbp-tm-menu {
    font-family: "Bebas Neue";
    font-size: 16px;
    color: #FFFFFF;
    text-decoration: none;
    text-transform: uppercase;
    background-color:#2b343b;
    margin:0;

}

/* first level menu items */
.cbp-tm-menu > li {
    display: inline-block;
    position: relative;
    padding-left:21px;

}

.cbp-tm-menu > li > a {
    line-height: 3em;
    padding-right:1em;
    font-size: 23px;
    display: block;
    color: #fff;

}

.no-touch .cbp-tm-menu > li > a:hover,
.no-touch .cbp-tm-menu > li > a:active {
    color: #e82c5c;
}

/* sumbenu with transitions */
.cbp-tm-submenu {
    position: absolute;

    visibility: hidden;
    opacity: 0;
    padding: 0;
    text-align: left;
    pointer-events: none;
    -webkit-transition: visibility 0s, opacity 0s;
    -moz-transition: visibility 0s, opacity 0s;
    transition: visibility 0s, opacity 0s;

}

.cbp-tm-show .cbp-tm-submenu {
    width: 10em;
    left: 30%;
    margin: 0 0 0 -8em;
    opacity: 1;
    visibility: visible;
    pointer-events: auto;
    -webkit-transition: visibility 0s, opacity 0.3s;
    -moz-transition: visibility 0s, opacity 0.3s;
    transition: visibility 0s, opacity 0.3s;
}

.cbp-tm-show-above .cbp-tm-submenu {
    bottom: 100%;
    padding-bottom: 10px;
}

.cbp-tm-show-below .cbp-tm-submenu {
    top: 100%;
    padding-top: 10px;
}
.cbp-tm-menu > li:hover
{
    background-color: Gray;

}


/* extreme cases: not enough space on the sides */
.cbp-tm-nospace-right .cbp-tm-submenu {
    right: 0;
    left: auto;
}

.cbp-tm-nospace-left .cbp-tm-submenu {
    left: 0;
}

/* last menu item has to fit on the screen */
.cbp-tm-menu > li:last-child .cbp-tm-submenu {
    /*right: 0;*/
}

/*  
arrow: depending on where the menu will be shown, we set 
the right position for the arrow
*/

.cbp-tm-submenu span {
    border: solid transparent;
    content: " ";
    height: 0;

您缺少 IE 的 CSS 渲染引擎。不同的浏览器有不同的渲染引擎。

1. Chrome-webkit
2. Firefox -moz
3. Opera -据我所知，opera已经改用开源-webkit渲染引擎。
4. Internet 浏览器。我认为 Internet Explorer 使用 Trident Rendering Engine。

-webkit-transition: 可见性 0s，不透明度 0.3s;

-moz-transition: 可见度0s，不透明度0.3s；

您应该在您的 CSS 中使用 Trident 引擎，就像您在 chrome 中使用 webkit 引擎一样。
