Trimming \n, \s, \t from javascript string
提问by JVG
I have a jQuery selector which gets the htmlwithin a selector, like so:
我有一个 jQuery 选择器，它在选择器中获取html，如下所示：
$('.pp-product-description .noindent').html()
Here's an example of the output, I've verified that it's a string:
这是输出的示例，我已经验证它是一个字符串：
<li class="standardBulletText">600 fill power down adds warmth without weight</li>
\r\n\t\t\t\t\t\t \t
<li class="standardBulletText">Matte shell with DriOff™ finish for water-resistant protection</li>\
r\n\t\t\t\t\t\t \t
<li class="standardBulletText">Snap-off, adjustable hood with removable faux fur trim</li>
\r\n\t\t\t\t\t\t \t<li class="standardBulletText">Hidden zip/snap closure except for top and bottom snaps</li>
I'm trying to trim this down so that the \r, \nand \tcharacters disappear. I'm currently using nodeJS' validatemodulewhich has a special sanitize(string).trim()command which should trim away white space. From the docs:
我正在尝试减少它，以便\r,\n和\t字符消失。我目前正在使用nodeJS'validate模块，它有一个特殊的sanitize(string).trim()命令，可以去除空白。从文档：
var str = sanitize(' \t\r hello \n').trim(); //'hello'
This has worked for me in the past, but here it isn't. I've also tried javascript's built in trim()method, as well as str.replace("\s+", "");, none are working.
这在过去对我有用，但在这里不是。我也试过 javascript 的内置trim()方法，以及str.replace("\s+", "");，都没有工作。
Any ideas on what I'm missing, or what I can do to get this working?
关于我缺少什么的任何想法，或者我可以做些什么来使它工作？
