Question

我在链接上运行以下代码： -

$('#expertprofiles-category-filters .filterby > a').on("click", function () {
    // Figure out which category to show.
    var categoryId = $(this).attr('rel');

    // Hide the other subfilters.
    $("div.category-panel[rel!=" + categoryId + "]").slideUp(100);

    // Show the subfilters of the category.
    $("div.category-panel[rel=" + categoryId + "]").delay(100).slideDown(400);
});

此代码运行正常，但问题是我也想在页面加载时运行此代码，以便自动选择任何一个链接。

我试过这个： -

$("#expertprofiles-category-filters .filterby").find('a').trigger('click');

但它不起作用......

感谢。

Answer 1

使用相同的选择器

$('#expertprofiles-category-filters .filterby > a').trigger('click');

Answer 2

您也可以采取以下方式，

$('#expertprofiles-category-filters .filterby > a').on("click", function () {
    // Figure out which category to show.
    var categoryId = $(this).attr('rel');

    // Hide the other subfilters.
    $("div.category-panel[rel!=" + categoryId + "]").slideUp(100);

    // Show the subfilters of the category.
    $("div.category-panel[rel=" + categoryId + "]").delay(100).slideDown(400);
}).trigger("click"); // triggers click on DOM ready
