javascript - Jquery 替换有前缀的单词

Question

我想问一下jquery中如何替换仅以$开头的单词，例如:

//$example and $friend here means nothing just a regular string
var txt = "This is just an $example my $friend";

我想替换字符串中以 $ 开头的所有单词将在 html 标记中替换，如下所示:

This is just an <span class="php-var">$example</span> my <span class="php-var">$friend</span>

我想在客户端执行此操作，以便节省服务器性能

Answer 1

如下:

var txt = "This is just an $example my $friend";
var txt = txt.replace(/\$\S+/g,  '<span class="php-var">$&</span>');
