如何在span类中删除文本字符串的一部分 [英] How to remove a a part of a text string in a span class

问题描述

我在span类中有两个文本字符串，我需要使用jQuery或vanilla Javascript删除其中的一部分.字符串是#AAA和#AAB

I have a two text strings in a span class and I need to remove a part of it with either jQuery or vanilla Javascript. The string is #AAA and #AAB

为了达到这个结果，我使用了一些变体，但是在这个span类上，它似乎不起作用.

I have used a few variations before for achieving this result, but on this span class it doesn´t seem to work.

这是我尝试过的脚本:

$j('document').ready(
function() {
$j("span.sku").text(function() {
return $(this).text().replace(/(#AAA |#AAB)/g, "");
}).addClass("remove");
});

和

$j('body').ready(function(){
$j( "span.sku:contains('#AAA')" ).addClass( "remove" );
$j( "span.sku:contains('#AAB')" ).addClass( "remove" );
});

最后一个我试图设置一个我可以用CSS隐藏的类.

The last one I tried to just set a class that I could hide with CSS.

$ j用于站点正在使用的非冲突模式.

The $j is for non-conflict mode that the site is using.

html:

<div class="product_meta">
 <span class="sku_wrapper">SKU: <span class="sku" itemprop="sku">K1J2AEA#AAA</span></span>
    <meta itemprop="brand" content="HP">
    <meta itemprop="gtin14" content="">
    <meta itemprop="itemCondition" itemtype="http://schema.org/OfferItemCondition" content="http://schema.org/NewCondition">
 <span class="posted_in">Categorie: <a href="/category/computers/notebooks/" rel="tag">Notebooks</a></span>
</div>

推荐答案

对于字符串文字，您需要使用'或"，还需要删除正则表达式中的(space)

You need to use ' or " for string literals also need to remove the (space ) in the regex

var $j = jQuery.noConflict(true);

$j(function($) { //dom ready handler receives a jQuery object reference as its parameter so you can assign it ti $ and use it inside the handler
  $("span.sku").text(function(i, text) {
    return text.replace(/#AAA|#AAB/g, "");
  }).addClass('remove');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<div class="product_meta">
  <span class="sku_wrapper">SKU: <span class="sku" itemprop="sku">K1J2AEA#AAA</span></span>
  <meta itemprop="brand" content="HP">
  <meta itemprop="gtin14" content="">
  <meta itemprop="itemCondition" itemtype="http://schema.org/OfferItemCondition" content="http://schema.org/NewCondition">
  <span class="posted_in">Categorie: <a href="/category/computers/notebooks/" rel="tag">Notebooks</a></span>
</div>
