从引导选项卡捕获“显示"事件 [英] Capturing 'shown' event from bootstrap tab

问题描述

我的页面上有一些静态" HTML:

I have some 'static' HTML on my page:

<div id="DIVISIONS">
    <ul class="nav nav-tabs" id="DIVISIONTABS">
        @* <li> nodes will be injected here by javascript *@
    </ul>
    <div class="tab-content" id="DIVISIONTABPANES">
        @* <div class="tab-pane"> nodes will be injected here by javascript *@
    </div>
</div>

在页面加载时，我会创建一个标签框架"，即创建引导标签和标签内容容器.

On page load, I create a tab 'framework', i.e. create the bootstrap tabs and tab content containers.

我通过以下方式触发该过程

I trigger the process with:

$(window).bind("load", prepareDivisionTabs);

"prepareDivisionTabs"会执行以下操作:

And "prepareDivisionTabs" does this:

function prepareDivisionTabs() {
    // Retrieve basic data for creating tabs
    $.ajax({
        url: "@Url.Action("GetDivisionDataJson", "League")",
        cache: false
    }).done(function (data) {
        var $tabs = $('#DIVISIONTABS').empty();
        var $panes = $('#DIVISIONTABPANES').empty();
        for (var i = 0; i < data.length; i++) {
            var d = data[i];
            $tabs.append("<li><a href=\"#TABPANE" + d.DivisionId + "\" data-toggle=\"tab\">" + NMWhtmlEncode(d.Name) + "</a></li>");
            $panes.append("<div id=\"TABPANE" + d.DivisionId + "\" class=\"tab-pane\"></div>")
        }
        renderDivisionTabPaneContents(data);
    }).fail(function (err) {
        alert("AJAX error in request: " + JSON.stringify(err, null, 2));
    });
}

有关信息，上面的"renderDivisionTabPaneContents"是这样做的:

For info, the "renderDivisionTabPaneContents" in the above does this:

function renderDivisionTabPaneContents(data) {
    for (var i = 0; i < data.length; i++) {
        var d = data[i];
        renderDivisionTabPaneContent(d.DivisionId);
    }
}

function renderDivisionTabPaneContent(id) {
    var $tabPane = $('#TABPANE' + id);
    $tabPane.addClass("loader")
    $.ajax({
        url: "/League/GetDivisionPartialView?divisionId=" + id,
        cache: false
    }).done(function (html) {
        $tabPane.html(html);
    }).fail(function (err) {
        alert("AJAX error in request: " + JSON.stringify(err, null, 2));
    }).always(function () {
        $tabPane.removeClass("loader")
    });
}

到目前为止一切顺利.我的页面已加载，我的标签内容已呈现，当我单击其他标签时，将显示相关内容.

All good so far. My page loads, my tab contents are rendered, and when I click the different tabs, the relevant content is shown.

现在，我不想在开始时加载所有内容，而是希望通过使用选项卡的显示"事件来实时加载选项卡内容.为了对此进行测试，我只想确保在显示选项卡时可以收到JavaScript警报.因此，我创建以下代码来触发标签显示事件的附件:

Now, rather than loading all content at the start, I want to load tab content just-in-time by using the 'shown' event of the tabs. To test this, I've wanted to just make sure I could get a javascript alert when the tab was shown. So, I create the following to trigger the attachment of tab shown events:

$(function () {
    attachTabShownEvents();
})

哪个调用:

function attachTabShownEvents() {
    $(document).on('shown', 'a[data-toggle="tab"]', function (e) {
        alert('TAB CHANGED');
    })
}

因此，我希望在更改标签后看到"TAB CHANGED"警报.但是...我没有看到任何警报.

I'd therefore expect so see the "TAB CHANGED" alert after the change of tab. But ... I see no alerts.

有人可以帮我吗?

推荐答案

选项卡更改的正确事件绑定是shown.bs.tab.

The correct event binding for tab change is shown.bs.tab.

$(document).on('shown.bs.tab', 'a[data-toggle="tab"]', function (e) {
    alert('TAB CHANGED');
})
