jquery nearest（）不起作用

Question

I am trying to grab the closest link with the class a.tariff-link and send it to a method, but looks like closest() cannot find it because it's always passing an undefined element.

$(".ui-icon-triangle-1-e").click(function () {

    GetRuleData($(this).closest("a.tariff-link"));

});

An example of HTML would be like this:

<h3 class="ui-accordion-header ui-helper-reset ui-state-default ui-corner-all" role="tab" aria-expanded="false" tabindex="-1">
<span class="ui-icon ui-icon-triangle-1-e"></span>
<a id="41965" class="tariff-link" href="#" tabindex="-1">
</h3>

Answer 1

You need .siblings() instead of .closest() . The latter checks the current element and its ancestors but your a is a sibling of the current element, not an ancestor.

If it's always the element right after the current element you could also use .next() .

Answer 2

尝试：

GetRuleData($(this).next("a.tariff-link"));
