我有一个带有前导点的 javascript 字符串.我想使用javascript替换功能删除前导点.我尝试了以下代码.

I have a javascript string which have a leading dot. I want to remove the leading dot using javascript replace function. I tried the following code.

var a = '.2.98»';
document.write(a.replace('/^(\.+)(.+)/',"$2"));

但这行不通.有什么想法吗?

But this is not working. Any Idea?

推荐答案

以下内容将字符串开头的点替换为空字符串，字符串的其余部分保持不变:

The following replaces a dot in the beginning of a string with an empty string leaving the rest of the string untouched:

a.replace(/^\./, "")
