从日期字符串中删除零

Question

I have a string with the following format: '01/02/2016' and I am trying to get rid of the leading zeros so that at the end I get '1/2/2016' with regex.

Tried '01/02/2016'.replace(/^0|[^\\/]0./, ''); so far, but it only gives me 1/02/2016

Any help is appreciated.

Answer 1

Replace \\b0 with empty string. \\b represents the border between a word character and a non-word character. In your case, \\b0 will match a leading zero.

 var d = '01/02/2016'.replace(/\\b0/g, ''); console.log(d); 

Answer 2

You can use String.prototype.replace() and regular expression to replace the zero at the binning and the zero before / like this:

 var d = '01/02/2016'.replace(/(^|\\/)0+/g, '$1'); console.log(d);
