正则表达式：匹配单词和特殊字符，除非用引号引起来

Question

I've already had a look at other questions which are nearly identical, and with a little customization I've found a solution that works in RegExr . The problem is that it doesn't work in Javascript.

Expression: ([^\\s]*"[^"]+"[^\\s]*)|[^"]?\\w+[^"]?

Test string: +w1 @w2 (w3 (w4) @"w5 6"

Expected result: ['+w1', '@w2', '(w3', '(w4)', '@"w5 w6"']

Javascript code: console.log(/([^\\s]*"[^"]+"[^\\s]*)|[^"]?\\w+[^"]?/g.exec(test_str));

Javascript result: ["+w1 ", undefined] (tested in FF15 and Chrome 22)

I've looked up documentation on the MDN, but there are no other relevant flags than the global flag. Just to try I've added multiline and case-insensitive flags, but they were no use.

Any idea what makes it break in Javascript while it seems to work in RegExr? (And isn't Flash' Actionscript also ECMAScript, so shouldn't RegExr use the same regex engine?) In RegExr, the only enabled flag is the global flag.

Edit: Another issue is that "w1 \\"w2\\" w3" will be matched as two words while it should be one word. Any ideas?

尝试：

console.log('+w1 @w2 (w3 (w4) @"w5 6"'.match(/[^"\s]+(?:".*"\S*)?/g));
