在Javascript中删除字符串的第一个字符 [英] Delete first character of a string in Javascript

问题描述

如果第一个字符是0，我想删除字符串的第一个字符.0可以不止一次。

I want to delete the first character of a string, if the first character is a 0. The 0 can be there more than once.

是否有一个简单的检查第一个字符并删除它的函数是否为0？

Is there a simple function that checks the first character and deletes it if it is 0?

现在，我正在尝试使用JS slice（）函数但它非常笨拙。

Right now, I'm trying it with the JS slice() function but it is very awkward.

推荐答案

var s = "0000test";
while(s.charAt(0) === '0')
{
 s = s.substr(1);
}

这会杀死字符串开头的任何0。

This will kill any 0's at the start of the string.
