获取指定的父元素，然后找到指定的子元素

I have this HTML structure

我有这个HTML结构

<div class="parent_wrapper">
    <div class="child_element_one">
    </div>
    <div class="child_element_two">
        <p></p>
    </div>
    <div class="child_element_three">
        <a href="#">Click to test</a>
    </div>

and the script that I tried to work with it (my attempt so far)

以及我尝试使用它的脚本(我的尝试到目前为止)

$('.child_element_three a').click(function(e){
    $(this).parents('parent_wrapper').find('.child_element_two p').text("added to the div that has a class of child_element_two paragraph");
});

Problem: added to all div that has a class of child_element_two paragraph, what I want is only add text to the .child_element_two paragraph of the same group that has the current triggered link or the current group of the click link. How to do that?

问题:添加到具有class_element_two段的所有div中,我想要的只是将文本添加到具有当前触发链接的同一组的.child_element_two段或点击链接的当前组。怎么做?

4 个解决方案

#1

You are missing the class selector in parent_wrapper, you have used it as a element selector.

您缺少parent_wrapper中的类选择器,您已将其用作元素选择器。

Also change .parents() to closest() since you want only the first parent matching the selector

同时将.parents()更改为nearest(),因为您只需要匹配选择器的第一个父级

$(this).closest('.parent_wrapper').find('.child_element_two p').text("added to the div that has a class of child_element_two paragraph");

Demo: Fiddle

#2

I think you can use .siblings in this task:

我想你可以在这个任务中使用.siblings:

$('.child_element_three a').click(function (e) {
     $(this).parent().siblings('.child_element_two').find('p').text("added to the div that has a class of child_element_two paragraph");
});

#3

 $('.child_element_three a').click(function(e){
     $(this).parents('.parent_wrapper').find('.child_element_two p').text("added to    the div that has a class of child_element_two paragraph");
 });

U missing the. in parents('.parent_wrapper').

你错过了。在父母('.parent_wrapper')中。

#4

you can try:

你可以试试:

$('.child_element_three a').click(function(e){
    $(this).parent().find('.child_element_two p').text("added to the div that has a class of child_element_two paragraph");
});
