javascript split string by space, but ignore space in quotes (notice not to split by the colon too)
提问by Elad Kolberg
I need help splitting a string in javascript by space (" "), ignoring space inside quotes expression.
我需要帮助将 javascript 中的字符串按空格 (" ") 拆分，忽略引号表达式中的空格。
I have this string:
我有这个字符串：
var str = 'Time:"Last 7 Days" Time:"Last 30 Days"';
I would expect my string to be split to 2:
我希望我的字符串被拆分为 2：
['Time:"Last 7 Days"', 'Time:"Last 30 Days"']
but my code splits to 4:
但我的代码拆分为 4：
['Time:', '"Last 7 Days"', 'Time:', '"Last 30 Days"']
this is my code:
这是我的代码：
str.match(/(".*?"|[^"\s]+)(?=\s*|\s*$)/g);
Thanks!
谢谢！

s = 'Time:"Last 7 Days" Time:"Last 30 Days"'
s.match(/(?:[^\s"]+|"[^"]*")+/g)
// -> ['Time:"Last 7 Days"', 'Time:"Last 30 Days"']
Explained:
解释：
(?: # non-capturing group
[^\s"]+ # anything that's not a space or a double-quote
| # or…
" # opening double-quote
[^"]* # …followed by zero or more chacacters that are not a double-quote
" # …closing double-quote
)+ # each match is one or more of the things described in the group
Turns out, to fix your original expression, you just need to add a +on the group:
事实证明，要修复您的原始表达式，您只需要+在组上添加一个：
str.match(/(".*?"|[^"\s]+)+(?=\s*|\s*$)/g)
# ^ here.

ES6 solution supporting:
ES6 解决方案支持：
- Split by space except for inside quotes
- Removing quotes but not for backslash escaped quotes
- Escaped quote become quote
- 除内引号外，按空格分割
- 删除引号但不是用于反斜杠转义引号
- 转义报价成为报价
Code:
代码：
str.match(/\?.|^$/g).reduce((p, c) => {
if(c === '"'){
p.quote ^= 1;
}else if(!p.quote && c === ' '){
p.a.push('');
}else{
p.a[p.a.length-1] += c.replace(/\(.)/,"");
}
return p;
}, {a: ['']}).a
Output:
输出：
[ 'Time:Last 7 Days', 'Time:Last 30 Days' ]

This Works for me..
这对我有用..
var myString = 'foo bar "sdkgyu sdkjbh zkdjv" baz "qux quux" skduy "zsk"'; console.log(myString.split(/([^\s"]+|"[^"]*")+/g));
var myString = 'foo bar "sdkgyu sdkjbh zkdjv" baz "qux quux" skduy "zsk"'; console.log(myString.split(/([^\s"]+|"[^"]*")+/g));
Output:Array ["", "foo", " ", "bar", " ", ""sdkgyu sdkjbh zkdjv"", " ", "baz", " ", ""qux quux"", " ", "skduy", " ", ""zsk"", ""]
输出：数组 ["", "foo", " ", "bar", " ", ""sdkgyu sdkjbh zkdjv"", " ", "baz", " ", ""qux quux"", " ", " skduy", " ", ""zsk"", ""]
