Javascript如何在replace（）函数中跳过$＆

Question

如何跳过在replace（）函数中替换特殊的$＆

我尝试添加\（$ \＆），但没有任何结果

var url = 'http://www.example.com/?a=b&c=c&d=$cid$&e=e';
var txt = 'Lorem ipsum dolor sit amet, {link} consectetur adipiscing elit. {link} id porttitor quam rhoncus in.';
var output = txt.replace(/{link}/gi, url);
console.log(output);

.as-console-wrapper { max-height: 100% !important; top: auto; }

Answer 1

使用$$代替$

或使用此url.replace(/\$/g, '$$$$')

修复网址本身

var url = 'http://www.example.com/?a=b&c=c&d=$cid$&e=e';
var txt = 'Lorem ipsum dolor sit amet, {link} consectetur adipiscing elit. {link} id porttitor quam rhoncus in.';
var output = txt.replace(/{link}/gi, url.replace(/\$/g, '$$$$'));
console.log(output);
