jQuery 对话框中的 Z-index.自动建议列表未正确显示

2022-01-15 00:00:00 dialog javascript css jquery-ui z-index

在 jQuery 对话框中显示自动建议框时出现问题.无论如何，自动建议列表都会显示在对话框下方.我尝试将 autosuggest 的 z-index 属性设置为 > 1004.但没有运气.

I have a problem displaying the autosuggest box inside a jQuery dialog. The auto suggest list is displayed under the dialog no matter what. I have tried setting up the z-index property of autosuggest to > 1004. But no luck.

下面是截图.

这是我用来设置自动建议列表样式的 CSS 类:

This is the CSS class I have used to style the autosuggest list:

ul.as-list {
    position: absolute;
    list-style-type: none;
    margin: 2px 0 0 0;
    padding: 0;
    font-size: 14px;
    color: #000;
    font-family: "Lucida Grande", arial, sans-serif;
    background-color: #fff;
    background-color: rgba(255,255,255,0.95);
    box-shadow: 0 2px 12px #222;
    -webkit-box-shadow: 0 2px 12px #222;
    -moz-box-shadow: 0 2px 12px #222;
    border-radius: 5px;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    z-index:6000;
}

li.as-result-item, li.as-message {
    margin: 0 0 0 0;
    padding: 5px 12px;
    background-color: transparent;
    border: 1px solid #fff;
    border-bottom: 1px solid #ddd;
    cursor: pointer;
    border-radius: 5px;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    z-index:6000;
}

我已经在 jsfiddle 页面上传了完整的代码.你可以清楚地看到那里的问题.我该如何解决?

I have uploaded the complete code in this jsfiddle page. You can see the problem there clearly. How can I fix it?

推荐答案

根本原因是最外面的两个元素有overflow: hidden.

The root cause is that the outermost two elements have overflow: hidden.

解决这个问题的最简单方法是:

The simplest way to fix that is:

.ui-dialog, .ui-dialog-content {
    overflow: visible !important
}

如果你对使用 !important 不满意(这不是好的做法)，你可以找到 overflow: hidden 实际应用的地方，并修复它在那里.

If you're not happy with using !important (it's not good practise), you can find the place where overflow: hidden is actually being applied, and fix it there.
