Question

如何在父级内部调用父元素？

例如，我在页面上有多个这些

<div class="parent">
    <div class="some-text">text</div>
    <div class="some-image">image</div>
    <div class="some-btn">btn</div>
</div>
<div class="parent">
    <div class="some-text">text</div>
    <div class="some-image">image</div>
    <div class="some-btn">btn</div>
</div>
<div class="parent">
    <div class="some-text">text</div>
    <div class="some-image">image</div>
    <div class="some-btn">btn</div>
</div>

当我点击.some-btn时，我只想知道那个.parent元素，其中.some-btn是一个孩子/点击。

我的jquery现在看起来像这样

$(".some-btn").click(function() {
    $(".some-text").toggleClass("active",1000,"easeInOutQuad");
    $(".some-image").toggleClass("active",1000,"easeInOutQuad");
    $(".some-btn").toggleClass("active");
})

但这当然会激活所有.parent元素。

Answer 1

选择单击元素的父元素，然后在此元素内选择：

$(".some-btn").click(function() {
    var that = $(this);
    var par = that.closest('.parent');
    par.find(".some-text").toggleClass("active",1000,"easeInOutQuad");
    par.find(".some-image").toggleClass("active",1000,"easeInOutQuad");
    that.toggleClass("active");
})

Answer 2

您需要遍历最近的父div，然后在其中找到元素：

$(".some-btn").click(function() {
  var _this = $(this);
  var closestparent = _this.closest('.parent')
  closestparent.find(".some-text,.some-image").toggleClass("active",1000,"easeInOutQuad");
 _this.toggleClass("active");
});

＆＃13;

 $(".some-btn").click(function() {
      var _this = $(this);
      var closestparent = _this.closest('.parent')
      closestparent.find(".some-text,.some-image").toggleClass("active",1000,"easeInOutQuad");
      _this.toggleClass("active");
    });

＆＃13;

.active{
color:red;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="parent">
    <div class="some-text">text</div>
    <div class="some-image">image</div>
    <div class="some-btn">btn</div>
</div>
<div class="parent">
    <div class="some-text">text</div>
    <div class="some-image">image</div>
    <div class="some-btn">btn</div>
</div>
<div class="parent">
    <div class="some-text">text</div>
    <div class="some-image">image</div>
    <div class="some-btn">btn</div>
</div>
