I want to continue one task because my head has some problem with a regular expression. How can it be done with a regular expression and jQuery?
我想继续执行一项任务,因为我的头部对正则表达式有一些问题。如何使用正则表达式和jQuery?
I have this HTML:
我有这个HTML:
<div class="test"> > > Presentation Text </div>
And I want to get just this text from all this string, every time at the beginning I have
而且我希望每次开始时都能从这个字符串中得到这个文本
" > > " + Some text ... these special character are not changing every time at the begin .
“ > > ” +有些文字......这些特殊字符在每次开始时都不会改变。
One way is:
一种方法是:
$('.test').html($('.test').html().replace(/&[^;]+;/g, ''));
It works, but I realized that I have at the end some bad characters and I have to remove "\n\n\n" as well
它有效,但我意识到我最后有一些不好的角色,我必须删除“\ n \ n \ n”以及
My output:
Presentation Text\n\n\n
But I need the clean text without "\n" or something else, just "Presentation Text"
但我需要没有“\ n”或其他东西的干净文本,只需要“演示文稿”
What can I do to solve this problem?
我该怎么做才能解决这个问题?

Since you're using jQuery, you can use $.trim to remove white-spaces from the beginning and end of your string.
由于您使用的是jQuery,因此您可以使用$ .trim从字符串的开头和结尾删除空格。

$('.test').html($('.test').html().replace(/&[^;]+;|\s+$/g, ''));
This will remove all the whitespace characters (\n, \t, space etc) from the end of the text.
这将删除文本末尾的所有空白字符(\ n,\ t,空格等)。
