jQuery Remove specific span based on id
提问by Э?ad Дьdulя?мaи
I want to be able to remove only spans which has an id that stars with the key word "junk_"
我希望能够仅删除具有以关键字“junk_”开头的 id 的跨度
for example if I have
例如，如果我有
<span id="junk_8345">A</span>
<span id="valid_2972">B</span>
<span id="junk_9249">C</span>
The output should look like
输出应该看起来像
<span id="valid_2972">B</span>
I've tried to use
我试过用
$("span:has(junk)").remove();
but it does not seem to work. I'm open to use regex expression with the replace function if I can accomplish the same goal. Any help would be greatly appreciated!
但它似乎不起作用。如果可以实现相同的目标，我愿意将正则表达式与替换函数一起使用。任何帮助将不胜感激！

use the startswithselector.
使用startswith选择器。
$('span[id^="junk"]').remove();

Based on what the API page give about "selectors" ( http://api.jquery.com/category/selectors/), I suggest you trying to use the start with ^=.
根据 API 页面提供的关于“选择器”（http://api.jquery.com/category/selectors/）的内容，我建议您尝试使用^=开头。
