How does Sublime3 detect regular expressions?

1 I want to get the code with the rule. The key is that if you have spaces, you can"t detect all the code.
2 Code:

onclick="_msq.push(["trackEvent", "81190ccc4d52f577-AA20194+2_58_1_333", "//item.mi.com/product/10000064.html", "pcpid", "31pchomephone_right_0001019-sharpt=normal&page=home&act=other&bid=3185161.1&pid=2174100024&adm=4849"]);">

3 my following rules do not get spaces, only ,"/ / item.mi.com/product/10000064.html" are detected, and

is not found before and after.
