用破折号替换空格的正则表达式

I'm trying to work out what regular expression I would need to take a value and replace spaces with a dash (in Javascript)?

我想弄清楚需要使用什么正则表达式来获取值，并用破折号(在Javascript中)替换空格?

So say if I had North America, it would return me North-America ?

如果我有北美，它会把我送回北美吗?

Can I do something like var foo = bar.replace(' ', '-') ?

我能做点什么吗?替换(',' - ')?

It's better to use:

最好使用:

var string = "find this and find that".replace(/find/g, "found");

to replace all occurrences.

将所有事件。

Yes, you can. Why didn't you try this before asking?

是的,你可以。你为什么不问之前不试试这个?

The best source of information for regular expressions in various languages that I've found is Regular-Expressions.info (and I linked directly to the Javascript section there).

在我所发现的各种语言中，正则表达式的最佳信息来源是正则表达式。info(和我直接链接到那里的Javascript部分)。

As for your particular question, yes, you can do something like that. Did you try it?

至于你的问题，是的，你可以这么做。你试一试吗?

var before = 'North America';
var after = before.replace(/ +/g, '-')
alert('"' + before + '" becomes "' + after + '"');

Use the site I showed you to analyze the regex above. Note how it replaces one or more spaces with a single hyphen, as you requested.
