javascript - 我可以用 jQuery 代码模拟点击超链接吗？

Question

我看过一些 Stack Overflow 帖子，它们显然与我的问题有关，但似乎没有一个符合我的要求。

我有一个嵌套结构来在报告中显示层次结构(业务部门和品牌):

<tr class="BrandRow1">
    <td>

    </td>
</tr>
<tr class='BrandRow1 StoreRow1'>
...
</tr>
<tr class='BrandRow1 StoreRow2'>
...
</tr>

在此布局中，我使用 A 标签显示/隐藏“子”内容(通过使用 class 属性。

加载时，如果 $('.StoreRow2').length 小于 4，我想显示所有“节点”。

我使用一个函数来进行切换:

// Allow an item to toggle other items' visibility
$(".VisibilityToggle").click(function () {
    var ControlledClass = findClass($(this), "Toggles-");
    if (ControlledClass != "") {
        $("." + ControlledClass).toggle();
        var Text = $(this).attr("rel");
        if (Text != "") $(this).attr("rel", $(this).attr("rev")).attr("rev", Text).text(Text);
    }
    return false;
});

我想做的是通过从 JS 代码调用它来触发“切换”打开。

我认为像 '$(".VisibilityToggle").click()` 这样的东西会做我想做的事，但这在我的代码中似乎不起作用，但如果我调用它，会手动通过 Chrome 中的 JS 控制台。我怀疑这与我在事件绑定(bind)到页面之前运行的代码有关。

你能帮忙吗？

Answer 1

你可以使用触发器:

$(".ABrand").trigger('click');

这是你想要达到的目标吗？
