javascript - Bootstrap-tour 不适用于表格行

Question

我正在尝试突出显示表格行。即使有了针对 z-indexes 等的 Bootstrap 修复 github issue link

看看这个 fiddle :jsFiddle

JavaScript

$("#dialog").dialog(); 
var t = new Tour({
 backdrop: true,
 onShown: function(tour) {
    var stepElement = getTourElement(tour);
    $(stepElement).after($('.tour-step-background'));
    $(stepElement).after($('.tour-backdrop'));
},
steps: [
    {
        element: "table tbody tr:first-of-type",
        title: "Title",
        placement: 'bottom',
        content: "Content"
    }        
]
}).restart();


function getTourElement(tour){
   return tour._options.steps[tour._current].element
}

HTML

<table>
    <thead>
        <tr>
            <th>Name</th>
            <th>Power</th>
            <th>Health</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>Superman</td>
            <td>Flying</td>
            <td>100%</td>
        </tr>
        <tr>
            <td>Superman</td>
            <td>Flying</td>
            <td>100%</td>
        </tr>
        <tr>
            <td>Superman</td>
            <td>Flying</td>
            <td>100%</td>
        </tr>
    </tbody>
</table>

CSS

table{
    width:100%;
}
.tour-step-background, 
.tour-backdrop {
    position: fixed;
}

.tour-step-background {
    background: #fff;
}

如您所见，仅当您将其 css 更改为:display:block; 时，它才会显示(表行“tr”)但那样它就会失去它的风格。

你可以通过添加规则来解决这个问题

.tour-step-backdrop>td
{
  position: relative;
  z-index: 1101;
}
