jQuery:如果此HREF包含 [英] jQuery: If this HREF contains

问题描述

为什么我不能使它正常工作?

Why can't I get this to work??

$("a").each(function() {
    if ($(this[href$="?"]).length()) {
        alert("Contains questionmark");
    }
});

Ps .:这只是一个简化的示例，以使您更容易获得概述.

Ps.: This is just at simplifyed example, to make it easier for you to get an overview.

推荐答案

您可以直接选择感兴趣的元素.

You could just outright select the elements of interest.

$('a[href*="?"]').each(function() {
    alert('Contains question mark');
});

请注意，您使用的是上面的 attribute-ends-with选择器代码使用 attribute-contains选择器，这听起来像是您实际上瞄准.

Note that you were using the attribute-ends-with selector, the above code uses the attribute-contains selector, which is what it sounds like you're actually aiming for.
