Internet Explorer 11使用javascript RegExp的正则表达式错误中的语法错误 [英] internet explorer 11 Syntax error in regular expression error with javascript RegExp

问题描述

我在Internet Explorer 11中收到一个Syntax error in regular expression错误，并且尝试了以下选项:

chars = text.split(/(?!$)/u),
chars = text.split(new RegExp("(?!$)", 'u'))
chars = text.split(new RegExp('/(?!$)/', 'u'));

我很好奇我在这里想念的东西. [插入评论这在其他浏览器中如何正常工作]

解决方案

您正尝试使用带有unicode标志("u")的正则表达式，该标志 XRegExp 的库.

I am receiving a Syntax error in regular expression error in Internet Explorer 11 and I have tried the following options:

chars = text.split(/(?!$)/u),
chars = text.split(new RegExp("(?!$)", 'u'))
chars = text.split(new RegExp('/(?!$)/', 'u'));

I am curious what I am missing here. [insert comment how this works fine in other browsers]

解决方案

You are trying to use a regular expression with the unicode flag ("u") which is not supported by any Internet Explorer <= 11.

You can try to use a library like XRegExp.
