如何从 JavaScript 中的字符串中删除空白字符？
A trim is very easy, but I don't know how to remove them from insidethe string. For example:
修剪很容易，但我不知道如何将它们从字符串内部移除。例如：
222 334 -> 222334
222 334 -> 222334

Nick Craver has a good response, if you're OK with regex, go for it.
Nick Craver 有一个很好的回应，如果你对正则表达式没问题，那就去做吧。
I just want to add that you can do this without Regex as well. You can just use a normal JavaScript replace(), using the parameters (" ", "") to replace all whitespace with empty strings.
我只想补充一点，您也可以在没有 Regex 的情况下执行此操作。您可以使用普通的 JavaScript replace()，使用参数 (" ", "") 将所有空格替换为空字符串。
Update: Whoops, this won't work with multiple whitespaces.
更新：糟糕，这不适用于多个空格。

You can use a regex, like this to replace all whitespace:
您可以使用正则表达式，像这样替换所有空格：
var oldString = "222 334";
var newString = oldString.replace(/\s+/g,"");
Or for literally justspaces:
或者实际上只是空格：
var newString = oldString.replace(/ /g,"");

You can also do this without a regular expression or a replace-
您也可以在没有正则表达式或替换的情况下执行此操作
var string= string.split(' ').join('');
