在Wordpress中使用Jquery和CSS区分两个相同的HTML ID元素 [英] Distinguishing between two same HTML ID elements using Jquery and css in Wordpress

问题描述

我知道，拥有多个具有相同ID的HTML元素是一种不好的做法.但是在这种情况下，我需要专门修改它们中的任何一个.

I know that is a bad practice to have more than HTML elements having same ID. However such is my situation where I need to specifically modify either of them.

我已研究找到并找到关于 Jquery 方法'document.getElementByID'，该方法与第一个相似元素一起返回并让您可以使用 css 对其进行更改.使用该代码，我在下面编写了代码，但是没有用.

I researched around and found about Jquery method 'document.getElementByID' that returns with the first similar element and lets you change it using css. Using that I wrote the code below but it doesn't work.

$(document.getElementById('it_trending-3')).css({"display":"none"});

我已使用 CSS-JS-PHP在我的wordpress主题中添加了此代码wordpress插件，从中创建了一个快捷方式，然后添加了简码.有人可以指导我哪里以及哪里出了问题吗?

I have added this code in my wordpress theme using the CSS-JS-PHP wordpress plugin, created a shortcut from the same and then added the shortcode. Can someone please guide me what and where I went wrong?

还可以随意提出一个不同的功能，该功能可能会让我使用也许索引专门指向每个相同的ID元素.谢谢！

Also feel free to suggest a different function that would maybe let me specifically point to each of the same ID elements using maybe indexes. Thanks!

推荐答案

将一个类保留在要更改的div上:

Keep a class to the divs you want to change:

<div>
    <span id="a" class="test">1</span>
    <span id="b" class="test">2</span>
    <span>3</span>
</div>

Jquery会像这样:

The Jquery would go like this:

$(function() {
    var w = $("div");
    console.log($('#a').length);
    console.log($('body #a').length);
    console.log($('#a', w).length);
});

$(".test").first().css({"color":"orange"});
//or
$(".test:first").css({"color":"orange"});

但是，如果您想通过各种索引选择类中的任何特定元素，则需要这样做:

But if you want to select any specific element with the class via an index of sorts, then you would need to do it like this:

var x = $(".test");
$(x[1]).css({"color":"orange"});
