Testing if a character exists with Regex

Question

I have a few strings that I am trying to match against

Cafe Team Member: Grovedale (Featured)
Cafe Team Member: Barwon Heads (Featured)
Cafe Team Member: Barwon Heads

What I have been able to come up with is /(?<=\:\s)(.+)(?=\s\()/g which will work for options one and two but 3 (because I am looking for an open bracket after the location) it will not work. I am stumped about how else I could go about this.

Where i have been testing

Edit:

Figured all i needed to add was |$ so it now looks like /(?<=\:\s)(.+)(?=\s\(|$)/g but when testing it in codepen it still isn't capturing the string correctly. Where regexr is saying it should work.

// vue stuff
new Vue({
    el: "#app",
    data: {
        titles: [
          "Cafe Team Member: Grovedale (Featured)",
          "Cafe Team Member: Barwon Heads (Featured)",
          "Cafe Team Member: Barwon Heads",
        ]
    }
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <template v-for="title in titles">
    <p>{{ title.match(/(?<=\:\s)(.+)(?=\s\(|$)/g) }}</p>
  </template>
</div>

Try using this regex:

(?<=:\s)[^(\r\n]+

Click for Demo

Explanation:

(?<=:\s) - positive lookbehind to match the position immediately preceded by a : followed by a white-space
[^(\r\n]+ - matches 1+ occurrences of any character that is neither a ( nor the newline characters. This will make sure to match all the characters until ( is found in the same line. If ( is not found, it matches till end of line.

Your regex doesn't match just because .+ must be followed with ?, which match as few times as possible. Without it, (.+) will match until the end of line and your positive lookahead will not match anything.

// vue stuff
new Vue({
    el: "#app",
    data: {
        titles: [
          "Cafe Team Member: Grovedale (Featured)",
          "Cafe Team Member: Barwon Heads (Featured)",
          "Cafe Team Member: Barwon Heads",
        ]
    }
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <template v-for="title in titles">
    <p>{{ title.match(/(?<=\:\s)(.+?)(?=\s\(|$)/g) }}</p>
  </template>
</div>
