Javascript equivalent of PHP's list()

由 烈酒焚心 提交于 2020-01-18 04:57:28
问题 Really like that function. $matches = array('12', 'watt'); list($value, $unit) = $matches; Is there a Javascript equivalent of that? 回答1: There is, in 'newer' versions of Javascript: Destructuring assignment - Javascript 1.7. It's probably only supported in Mozilla-based browsers, and maybe in Rhino. var a = 1; var b = 3; [a, b] = [b, a]; EDIT: actually it wouldn't surprise me if the V8 Javascript library (and thus Chrome) supports this. But don't count on it either Now supported in all

strptime in Javascript

由 拥有回忆 提交于 2019-12-11 03:37:32
问题 I have a date input field that allows the user to enter in a date and I need to validate this input (I already have server side validation), but the trick is that the format is locale dependent. I already have a system for translating the strptime format string to the the user's preference and I would like to use this same format for validating on the Javascript side. Any ideas or links to a strptime() implementation in Javascript? 回答1: After a few days of googling I found this implementation

preg_match_all JS equivalent?

由 不问归期 提交于 2019-12-03 11:24:09
问题 Is there an equivalent of PHP's preg_match_all in Javascript? If not, what would be the best way to get all matches of a regular expression into an array?
