我有以下标记:
<footer class="form__footer">
<div class="form__actions">
<div class="form__action form__action--primary">
<button class="button button--chevron-right button--primary"
name="next"
type="submit"
value="Next">Next
</button>
</div>
<div class="form__action form__action--secondary">
<button class="button button--chevron-left button--standout"
name="back"
type="submit"
value="Previous">Previous
</button>
</div>
</div>
</footer>
当下拉列表的值更改时,我想显示/隐藏下一个按钮。以下引发jquery语法错误:Syntax error, unrecognized expression: button, input[type='submit', name='next']
$( "footer.form__footer" ).find("button, input[type='submit', name='next']").hide();
以下内容隐藏了两个按钮:
$( "footer.form__footer" ).find("button, input[type='submit'][ name='next']").hide();
仅隐藏下一个按钮的正确语法是什么?

当您有按钮时为什么要引用输入,请使用:
$( "footer.form__footer" ).find("button[name='next']").hide();
setTimeout(function() {
$("footer.form__footer").find("button[name='next']").hide();
}, 500);

没关系,我已经知道了:
$( "footer.form__footer" ).find("button[name='next']").hide();

我假设您正在尝试从DOM中找到button
或input
元素。您可以尝试以下方法。这将从目标容器中隐藏匹配的元素
$( "footer.form__footer" ).find("button[type='submit'][ name='next'], input[type='submit'][ name='next']").hide();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<footer class="form__footer">
<div class="form__actions">
<div class="form__action form__action--primary">
<button class="button button--chevron-right button--primary"
name="next"
type="submit"
value="Next">Next
</button>
</div>
<div class="form__action form__action--secondary">
<button class="button button--chevron-left button--standout"
name="back"
type="submit"
value="Previous">Previous
</button>
</div>
</div>
</footer>

由于您的按钮仅包含特定单词,因此您也可以使用:contains
选择器来仅隐藏包含单词buttons
的{{1}}:
Next
$("footer.form__footer button:contains('Next')").hide();
