JS Regex - 替换字符串中的多个实例(JS Regex - Replace multiple instances in a string)

 我有这个字符串： 
 
var str = '"testFN, II testLN, II" < test1@test.com>, "testFN, Cal testLN, Cal" < test2@test.com>';
 
 而我在做 
 
str.replace(/(".*?),(.*?")/g, '$1__comma_$2');
 
 用字符串（__ comma_）替换多个逗号（，），仅在“”内。 
 
 事件虽然我给它/ g它没有替换所有实例。 它仅替换每个实例的第一个匹配项。 
 
 实际结果：“testFN__comma_ II testLN，II”<test1@test.com>，“testFN__comma_ testLN，Cal”<test2@test.com>预期结果：“testFN__comma_ II testLN__comma_ II”<test1@test.com>，“testFN__comma_ Cal testLN__comma_ Cal“<test2@test.com> 
 
 你能否提出任何我错过的建议？ 

I have this string:
 
var str = '"testFN, II testLN, II" < test1@test.com>, "testFN, Cal testLN, Cal" < test2@test.com>';
 
and I am doing
 
str.replace(/(".*?),(.*?")/g, '$1__comma_$2');
 
to replace multiple commas(,) with in a string(__comma_), only inside "".
 
Event though I given /g its not replacing the all instances. It replace only first match of each instance.
 
Actual Result: "testFN__comma_ II testLN, II" < test1@test.com>, "testFN__comma_ testLN, Cal" < test2@test.com> Expected Result: "testFN__comma_ II testLN__comma_ II" < test1@test.com>, "testFN__comma_ Cal testLN__comma_ Cal" < test2@test.com>
 
Can you please give any suggestions that I am missing anything ?
