正则表达式匹配不以特定字符串结尾的组

Question

I'm using javascript regex engine, and I have difficulties using a regex :

Here is a Sample (it's an ugly js script extraction of what I have to match):

{data = function() {[{id:"1441-aeze",name:"theme1"},{id:"1441-aezb",name:"theme2"},{id:"1441-aezc",name:"theme3-a"},{id:"1441-aezd",name:"theme1-mtr"},{id:"1441-aezf",name:"theme4"}]}}

My regex try :

id:"([^"]+)",name:"(?![^"]*mtr$)[^"]*"

Expected result for matching group 1:

Match[1] : 1441-aeze
Match[1] : 1441-aezb
Match[1] : 1441-aezc
Match[1] : 1441-aezf

But it's matching every portion of my sample. I don't understand why

Here is reg101 : Regex101 example

I'm not sure, what the $ in your lookahead is supposed to do, but unescaped it matches at the end of the string (or end of the line with m-Modifier) - but there is no end of a line at the end of your match. In your pattern, the " signals the end of the match, so you can just replace the $ with " to get it working, like id:"([^"]+)",name:"(?![^"]*mtr")[^"]*"
